Rhytidectomy, also known as facelift, is a surgical procedure that aims to rejuvenate facial soft tissues to achieve a more youthful and harmonious appearance. Now a common procedure, it was relatively unknown in the early 20th century because of negative public perceptions towards cosmetic surgery and secrecy among surgeons guarding their techniques . The first documented facelift was performed in 1901 by Eugene von Hollander, which involved excision and reapproximation of excess skin with minimal undermining. After World War I ended in 1918, the demand for reconstructive surgeries increased and so did the cultural acceptance of plastic surgery as a whole. However, it was not until after World War II, with the advent of antibiotics and the evolution of anesthesia, that a more aggressive approach to face lifting became practical.
In 1969, Swedish plastic surgeon Tord Skoog was the first to report a facelift procedure by dissecting along the superficial fascia of the face, leading to a longer-lasting outcome. This fascia was later termed the superficial musculoaponeurotic system (SMAS) described in anatomical studies by Mitz and Peyronie, which ultimately led to the surgical technique now known as “SMAS rhytidectomy." This approach involves either plication or imbrication of the SMAS, the former consisting of folding and suspending the SMAS, while the latter involves excision of excess SMAS and closure of the gap with suspension of the fascia.
The “tri-plane rhytidecomy” was introduced by Hamra in 1983 to include subcutaneous elevation of cervical skin to improve neck contouring. These approaches, however, do not address the melolabial fold or laxity of midface soft tissues. In 1990, Hamra introduced “deep-plane rhytidectomy” to further dissect zygomaticus musculature and ligaments in order to reposition the malar fat pad and hence efface the melolabial fold (MLF). In 1991, Hamra further modified his technique into the “composite rhytidecomy” to include the orbicularis oculi muscle in the dissection for improvement of the eyelid and cheek profile, allowing repositioning of the suborbicularis oculi fat (SOOF) to correct hollowing of the orbits from previous facelift procedures . Today, there are myriad variations of facelift techniques designed to address patient-specific priorities, from jowls to melolabial folds, platysmal banding, and length of the scar.
Anatomy and Physiology
Facial aging is due to the gravitational effect on soft tissues and weakening of suspensory ligaments, along with skin laxity, lipoatrophy, and bony resorption. This process results in the classic appearance of hollowing in the temporal, infracomissural, prejowl, and cheek areas. Sagging facial fat pads and surrounding anchoring ligaments deepen the MLFs, prejowl sulci, and nasojugal folds. Preferential bony resorption in the maxilla and periorbital bones also accentuates the palpebral-malar groove and causes sagging of lower eyelid soft tissues. Jowl formation from the descent of the buccal fat pad distorts the mandibular border and is a common reason for people to seek rhytidectomy. Jowls can often be addressed with SMAS rhytidectomy alone; however, if midface structures such as nasojugal folds or MLFs require rejuvenation, a deep-plane or composite rhytidectomy may be more appropriate.
A thorough understanding of anatomy, in particular the relationship of fascial planes to one another, is critical to the success of any surgery and the avoidance of complications. This is especially true in the face, where important structures are in close proximity and damage may alter the aesthetic appearance in a way that is not easily hidden or reversed. The elucidation of the SMAS in particular has had a huge impact on rhytidectomy, affecting both the current understanding of the facial aging process and the evolution of techniques to combat it. The SMAS is a fibrofatty layer of soft tissue overlying the parotid gland in the lateral face that invests the muscles of facial expression medially. It is contiguous with the platysma inferiorly and the temporoparietal fascia (TPF) or superficial temporal fascia superior to the zygomatic arch, and the SMAS attaches to the deep investing fascia of SCM posteriorly .
Another major consideration in any facial surgery is the location of the facial nerve. The facial nerve exits the temporal bone of the skull via the stylomastoid foramen and travels through the parenchyma of the parotid gland, where it divides into its main branches at the pes anserinus, so called because its branching appearance resembles that of a goose's foot. Classically, the facial nerve branches are described as 5 major divisions: frontal/temporal, zygomatic, buccal, marginal mandibular, and cervical, although several different branching patterns have been described . The nerve runs deep to SMAS and its contiguous layers, and innervates the mimetic muscles from their deep surfaces with the exception of the levator anguli oris, buccinator and mentalis muscles. During rhytidectomy, the frontal and marginal mandibular branches are the most commonly injured motor nerves, although the great auricular nerve (GAN) is still more frequently injured .
Cervicoplasty, or neck lift, is often performed at the same time as face lifting to achieve a balanced, rejuvenated appearance. The Dedo classification of the aging neck is often used to assess the condition of the skin, submental adipose tissue, platysma, and bone positioning . The goal of cervical rhytidectomy is to restore a youthful contour with a cervicomental angle of 90 to 105 degrees, and often to reduce excess submental fat and/or reduce the appearance of vertical platysmal bands.
Surgical Landmarks and Considerations
Pitanguy'sline: Approximates the course of the frontal branch of facial nerve: a line drawn from 0.5 cm below the tragus to 1.5 cm superior to the lateral brow. The nerve travels deep to the TPF and superficial to the superficial layer of deep temporal fascia .
McKinney’s point: Identifies the location of the GAN: 1/3 of the distance from the mastoid tip to the clavicular head of the sternocleidomastoid muscle (SCM). The GAN can be consistently found at this location at the posterior border of SCM before branching into anterior and posterior segments. The external jugular vein can also be found consistently 1 cm anterior to this location, parallel to the nerve .
Transverse facial artery: A branch of the superficial temporal artery, can be consistently found 2.5 cm lateral and 3 cm inferior to the lateral canthus. Injury to this vessel may contribute to necrosis of skin flaps and delay healing. There are usually buccal branches of the facial nerve superior and inferior to this vessel, and Stensen's duct from the parotid gland lies inferior to it but in the same fascial plane as well as the nerve branches.
Zuker’spoint: Used to identify the motor branch to the zygomaticus major muscle: midway along a line between the root of the helix and the oral commissure, and the nerve that crosses this point is typically the branch lying superior to the transverse facial artery .
Facial nerve arborization: In general, injuries to facial nerve medial to a vertical line through the lateral canthus may be less apparent due to redundancy and anastomoses of buccal and zygomatic branches in the midface, and do not generally warrant nerve exploration or repair.
Marginal mandibular nerve: Located superficial to facial vessels, often closely associated or even wrapping around the facial verin. The nerve can be found 1 to 2 cm below the inferior border of the mandible, just deep to the platysma .
Rhytidectomy is only one of many treatment modalities available to the aging face patient, serving to reposition soft tissue that has descended over time and reducing the amount of excess skin present. The type of facelift performed will be based on the patient’s aesthetic concerns. A thorough assessment of skin quality, rhytids, scars, fat descent and atrophy, and skeletal resorption must be performed during the pre-operative consultation to establish realistic expectations of surgical outcomes. Facial analysis and photography (frontal, lateral, oblique, and base view) with special attention to facial asymmetries, contour irregularities, and hairlines must be documented to ensure the patient and surgeon share expectations.
Patients primarily concerned with jowls or a sagging neck with or without platysmal banding may be offered a SMAS rhytidectomy and cervicoplasty. If deep MLFs or malar fat descent are a major feature, a deep-plane rhytidectomy or adjunctive mid-face lift is indicated. Composite rhytidectomy, which involves a deep-plane approach with additional repositioning of the SOOF, is indicated to further improve the lid-cheek junction.
Thus, the surgical approach will be dictated by the patient’s aesthetic concerns. Various rhytidectomy techniques can be combined with adjuvant therapies such as brow lift, blepharoplasty, cervicoplasty, subcutaneous fillers or fat transfer, and laser resurfacing to manage the aging face with a multi-level treatment approach.
Major medical comorbidities such as diabetes, immunocompromise, steroid requirements, bleeding diatheses, and connective tissue disorders can hamper wound healing. Smoking is also a major risk factor for skin flap necrosis because of the adverse impact it has on perfusion; radiation therapy can have a similar effect, and operating on these patients should be avoided . It is recommended that smoking cessation take place at least 2-4 weeks prior to surgery and be maintained for a month after surgery to allow optimal healing. In some cases, an history of severe sun exposure with multiple burns can also predispose patients to wound healing difficulties. Bleeding diatheses or requirements for blood thinners can be particularly problematic because they raise the risk of hematoma formation, which is already one of the more common complications in rhytidectomy. The use of medications and herbal supplements with anticoagulation properties should also be stopped, if possible, 2 weeks prior to surgery. Pre-operative assessment of any psychiatric history is also important to assess the patient’s motivation in seeking surgery. Patients with body dysmorphic disorder should undergo evaluation by a qualified mental health professional prior to considering surgery. Additionally, any major comorbidities that can be mitigated preoperatively should be addressed before undertaking a cosmetic procedure; patients who are poor candidates for surgery in general should probably not be offered a rhytidectomy.
A standard rhytidectomy instrument set should include at a minimum:
Facelift scissors, such as Gorney-Freeman, Kaye, Goldman-Fox, and Castanares scissors
Suture scissors, such as Mayo and iris or tenotomy scissors
Needle drivers, such as Halsey or Webster; Haney needle drivers may be useful for platysmaplasty, and some surgeons prefer Castroviejo needle drivers for fine suturing
Forceps, such as Adson-Brown, DeBakey, Gerald, or fine Castroviejo forceps
#15 blade scalpel and #3 handle
A facelift or breast retractor, with or without a light carrier
Headlight if no light carrier on the retractor
Bipolar and/or monopolar electrocautery
Sutures may include:
2-0 polydioxanone (PDS), polyester (Ethibond), or polyglactin (Vicryl) for suspension of SMAS and platysma
4-0 or 5-0 polyglactin or poliglecaprone (Monocryl) for deep dermal closure
5-0 or 6-0 polypropylene, nylon, or gut for skin closure
Staples for the scalp
Some surgeons may place drains and a pressure dressing with ice packs; others may avoid drains and consider using a fibrin tissue sealant to help eliminate dead space under the facial flaps. If other procedures, such as blepharoplasty, brow lift, fat transfer, or laser resurfacing are to be undertaken during the same anesthetic, additional equipment will be required.
As for most surgical procedures, a surgical technologist is required, as well as a circulating nurse. In most cases, rhytidectomy is performed under general anesthesia, which requires an anesthesia provider. An assistant to the surgeon will also make the procedure more efficient.
The patient is positioned supine on the operating table, and if the patient is intubated, suturing the endotracheal tube to one of the central maxillary incisors may help to keep the airway secure while permitting sufficient access to both sides of the face and neck. Povidone iodine or isopropyl alcohol may be used for skin preparation. Many surgeons will also inject significant amounts of local anesthetic or tumescent solution with dilute local anesthetic before and during the operation in order to minimize anesthetic drug requirements and maximize hemostasis to prevent postoperative bruising. Intravenous antibiotics and steroids may be administered as well.
Marking incisions: exact incision pattern will vary from surgeon to surgeon, but a Blair incision will typically start either within or along the inferior border of the temporal hair tuft and approach the root of the helix, at which point it will follow the junction of the auricle and the facial skin towards the tragus. The incision may proceed just medial to the posterior margin of the tragus in female patients (post-tragal approach) or within a skin crease anterior to the tragus (pre-tragal approach). The post-tragal approach may hide the scar better but risk winging the tragus laterally postoperatively, while the pre-tragal incision may result in a more apparent scar. Male patients will usually require a pre-tragal approach in order to avoid pulling hair-bearing skin onto the tragus during closure. The incision will then follow around where the lobule meets the cheek, often 1-2 mm onto the cheek skin rather than directly in the sulcus in order to prevent webbing. From there, the incision proceeds superiorly up the posterior surface of the auricle, approximately 1/3 of the way from the postauricular sulcus to the helical rim; as the scar contracts postoperatively, it will be pulled into the middle of postauricular sulcus if the incision is placed slightly onto the back of the concha during surgery, as described. The incision should then turn gently 90 degrees to enter the postauricular hairline at the narrowest portion of non-hair-bearing skin behind the ear, typically at the level of Darwin's tubercle. The incision then travels inferiomedially as far as necessary to prevent a standing cutaneous cone during closure .
Some surgeons mark the extent of skin flap as well
SMAS rhytidectomy: ~6 cm anterior to tragus
Deep-plane rhytidectomy: mark a line between the angle of the mandible and the lateral canthus, where the surgical plane will transition from subdermal to subSMAS
Marking surgical landmarks: Some surgeons find it helpful to identify the paths of the frontal, marginal mandibular, and great auricular nerves prior to incision, or to mark the angle of the mandible. Marking the vertical platysmal bands may also be helpful if a platysmaplasty is planned.
1. Cervicofacial liposuction: If needed, liposuction is performed prior to flap elevation; once flaps are elevated, maintaining suction with liposuction cannulae can be very challenging. Cannulae are introduced via stab incisions in the submental crease and inferior to the lobule, within the marked rhytidectomy incisions. A 3 mm liposuction cannula is introduced with the ports facing away from the dermis and gentle outward pressure is provided to tent the skin, thereby avoiding damage to the subcutaneous layer and the subdermal plexus.
2. Incision and flap elevation: With a scalpel beveled parallel to the hair follicles, the incision is carried down to the subcutaneous layer. A subcutaneous flap is then raised with facelift scissors. The operating room light is directed at the skin surface to aid with transillumination, which will help the surgeon maintain appropriate and consistent thickness of the flap. Proper counter-tension retraction is critical for this dissection in order to avoid buttonholing the skin.
3. SMAS rhytidectomy: After the SMAS has been exposed it can be reduced with either plication or imbrication.
Plication (folding): The SMAS is not violated in this approach. SupraSMAS adipose tissue is excised from the periauricular region, then the SMAS is folded onto itself and sutured in place with multiple superolateral and lateral vectors to achieve tightening.
Imbrication: Involves resection of redundant SMAS. SMAS is incised 1 cm anterior to the ear in a "J" shape and undermined. The SMAS is then advanced in multiple superolateral vectors from the lobule to the zygomatic arch and sutured in place. If desired, the SMAS incision can be made so as to create an inferiorly-based flap that is then transposed postauricularly in order to apply tension along the margin of the mandible and efface the jowls.
Blunt dissection vertically and along the course of the facial nerve is performed in the sub-SMAS plane to avoid damaging the facial nerve. Sutures should only pass through SMAS to avoid injury to the parotid gland deep to the plane of dissection.
The type of suspension sutures used is based on surgeon preference. Either a non-absorbable suture or a large absorbable suture can be used.
4. Deep Plane rhytidectomy: A similar subdermal skin flap is elevated until the SMAS is incised and the dissection dives deep.
An incision is made in the SMAS along a line from the malar eminence to the angle of the mandible. A blunt subSMAS dissection is then carried anteriorly over the parotidomasseteric fascia with its inferior limit at the inferior border of mandible and upper limit at the malar eminence.
The zygomaticus major muscle is identified and dissected on its superficial surface towards the MLF. As a result, the malar fat pad is elevated into the skin flap.
The flap is suspended posterosuperiorly, taking care to ensure appropriate and symmetric repositioning of the malar fat pads.
5. Minimal Access Cranial Suspension (MACS) lift : As an alternative to aggressive elevation and suspension, subdermal elevation can be performed and the soft tissue elevated with purse-string sutures.
A thin, vertical loop of 0 polydioxanone suture suspends the SMAS overlying the parotid as well as the superior aspect of the platysma muscle to the fascia of the temporalis muscle.
An broad, oblique loop suspends the SMAS above the jowl to the fascia of the temporalis muscle in order to improve mandibular definition.
The malar loop suspends the malar fat pad to the deep temporal fascia just lateral to the orbit, effacing the MLF.
Hemostasis: This is done in a meticulous fashion with bipolar cautery. Aggressive cautery can cause facial nerve injury and alopecia, while inadequate control of bleeding vessels may result in hematoma and flap necrosis.
Flap trimming and closure: The skin flap is redraped and secured at 2-4 points along the incision using staples or interrupted sutures. Excess skin is then removed and skin edges closed, taking care not to excise too much skin, which can lead to winging of the tragus, a pixie ear, or scar widening.
Suture use is based on surgeon preference. Deep dermal sutures are optional. In general, finer sutures (e.g. 6-0) is used to close pre- and post auricular skin, and occipital hairline can be closed with skin staples or resorbable sutures.
Care is taken to not disturb the natural hairline contour.
Excessive tension on the closure at the inferior border of the lobule can cause a pixie ear deformity.
Platysmaplasty: This may be performed before or after the facial elevation.
The previous submental liposuction incision is extended to 2-4 cm, and a supraplatysmal flap is raised. If the platysma is deficient in midline, the medial borders are identified. Excess fat is then sharply removed and the platysmal bellies are sutured together in the midline down past the level of the hyoid bone; some surgeons will also divide the platysma transversely at the level of the hyoid to improve the acuity of the cervicomental angle. Excess skin can be removed prior to closure as is performed in the facial rhytidectomy portion.
Dressing: Antibiotic ointment is applied to the incisions and a compressive dressing is placed to help prevent hematoma formation.
Postoperative care: The patient is seen at post-operative day 1 to remove the dressing and drains, then on day 7 to remove sutures and staples. Cold packs and pain medications are suggested for comfort. Antibiotics beyond the first 24 hours postoperatively are used at the discretion of the surgeon. Photographs are taken after 3 months of healing. The patient should avoid any heavy lifting or strenuous exercise and sleep with the head of bed elevated. No nose blowing is permitted.
As with any procedure, complications may occur in rhytidectomy despite careful preoperative optimization of medical comorbidities and meticulous intraoperative technique. As with any aesthetic procedure, the most common adverse outcome is dissatisfaction with the cosmetic result, which can result from a number of issues, most commonly scarring, asymmetry, contour irregularities, or an over/underdone appearance. Building a strong relationship with the patient prior to surgery will help the surgeon to guide the patient through any challenges that occur postoperatively, and may not only improve patient satisfaction, but also decrease the likelihood of litigation should a suboptimal result occur.
Hematoma. Hematoma is the most common complication following rhytidectomy, with a reported incidence of 0.2% to 8% . Hematomas can be categorized as either major or minor. Major bleeding episodes often occur within 24 hours of surgery with symptoms of subcutaneous mass, pain, and ecchymotic skin discoloration; these require surgical intervention for control of the hemorrhage. If this occurs in the neck, airway compromise may ensue, and the wound should be opened emergently. In contrast, minor bleeding tends to be delayed and may result from oozing of the subdermal plexus. These episodes can often be managed with watchful waiting or bedside drainage.
The risk of hematoma is increased by several factors including hypertension, male gender, coagulopathy or use of anticoagulants, post-anesthesia nausea, vomiting, and pain. Male skin is more vascular than female because of its hair follicles, which leads to a greater risk of bleeding. The use of antiplatelet medications or anticoagulants like aspirin and non-steroidal anti-inflammatory drugs (NSAIDS) and herbal supplements that are known to increase bleeding such as Ginkgo biloba, turmeric, St. John’s wort, ginseng, high dose vitamin C and E, fish oils, garlic, and glucosamine should also be stopped 2 weeks prior to surgery .
Hypertension remains the most significant risk factor contributing to hematoma formation. The goal is to maintain blood pressure below 150/90 mmHg. A study by Baker et al showed a reduction in overall incidence of postoperative hematoma in male rhytidectomy patients from 8.7% to 3.97% with strict blood pressure controls . Pre-operatively, sympatholytic medications such as valium or clonidine may be administered. Intraoperatively, meticulous hemostasis should be achieved prior to closure. Post-operatively, factors that can increase agitation in recovering patients such as nausea and pain should also be addressed promptly. The effect of drain placement on hematoma formation is unclear; however, drains may be able to reduce seroma formation.
Skin necrosis. This is often due to microvascular compromise from seroma or hematoma formation and comorbid conditions such as smoking and diabetes. Skin necrosis can involve partial-thickness or full-thickness dermis with eschar formation. In partial-thickness necrosis, patients present with skin discoloration and desquamation. This usually resolves with conservative wound care and heals well without scarring. Nitropaste or dimethylsulfoxide (DMSO) may be considered to improve perfusion. Full-thickness necrosis will lead to prolonged healing time with skin abnormalities such as dyspigmentation, contour irregularities, and scarring that require further intervention. It is important that wounds should be allowed to declare themselves first without aggressive debridement to avoid further damage. Patients who undergo rhytidectomy and skin resurfacing during the same anesthetic may be at a higher risk for skin necrosis.
A major risk factor for skin necrosis is smoking. Cigarette smoke contains nicotine, carbon monoxide, hydrogen cyanide, and nitric oxide, all of which have detrimental effects on microvascular oxygen transport and impair wound healing. In 1984, Rees et al showed a skin sloughing rate of 7.5% in smokers compared to 2.7% in nonsmokers ; given the increased risk of skin necrosis with smoking, some authors feels that the deep-plane facelift is safer in smokers because the thicker flap permits better perfusion . Most authors now agree that 2-4 weeks of smoking cessation before and after surgery is strongly recommended to avoid skin necrosis . Medications such as chemotherapy and steroids that can alter wound healing are also important to consider prior to rhytidectomy, and may result in a delay or cancellation of the procedure.
Lastly, skin closure should be performed without tension to avoid ischemia at the wound edges. The distal aspects of the flap, in the preauricular and superior postauricular areas, are the most susceptible to ischemic injury and therefore the most likely to develop necrosis.
Of note, patients undergoing revision rhytidectomy may have a lower risk of developing skin necrosis because their skin flaps have effectively been delayed since the prior surgery and have improved flow through choke vessels.
Nerve injury. With a reported incidence of 0.7% to 2.5%, nerve injury can best be avoided by understanding the relevant anatomy and careful surgical technique . Surgical landmarks described previously in this review are important to keep in mind when performing facial dissection. Although the use of intraoperative nerve monitors can help avoid nerve injuries, nerves are often injured by aggressive retraction and electrocautery, particularly when a vessel, like the facial vein or external jugular vein, begins to bleed near a nerve - the marginal mandibular and GAN, respectively. If a nerve is transected and recognized during surgery, immediate microsurigical epineurial repair is recommended. Motor nerve injuries may take a year to recover, or may never fully recover, but they can often be managed in the meantime with botulinum toxin injections to the contralateral facial muscle groups to improve symmetry, particularly in the case of frontal or marginal mandibular branch injury.
The most common nerve injured during rhytidectomy is the GAN, particularly during posterior skin flap elevation. This can cause anesthesia to the inferior pinna and mastoid skin with patients reporting difficulty placing earrings, using telephones, or combing their hair . The frontal and marginal mandibular branches of the facial nerve are the most commonly injured motor nerves during rhytidectomy . Careful elevation of a subcutaneous flap over the zygomatic arch and sub-platysmal flap around the angle of mandible will help avoid injury to these nerves; if bleeding occurs in these areas, consider application of pressure and a clotting agent, such as thrombin or cellulose, rather than cautery.
Surgical site infection. Cellulitis or abscess formation is, fortunately, a rare complication due to the robust blood supply of the face. Wound infections are most commonly caused by gram-positive cocci such as Staphylococcus or Streptococcus, and they generally resolve with antibiotics targeting skin flora.
Scarring and skin irregularities. While the incisions used for facelifts tends to be long, careful placement can usually minimize their appearance postoperatively. When scars do widen, they tend to do so in the postauricular area, generally due to excessive tension at closure, but fortunately, they are rarely noticeable in this location. Widened, pigmented, or erythematous scars in the preauricular area can be treated with laser resurfacing, steroid injections, or potentially with hydroquinone. Avoidance of sunlight for the first 12 months after surgery will also help to prevent noticeable scars. Hypertrophic or keloid scars may also benefit from silicone sheeting or operative revision after 6-12 months.
Another related complaint is subdermal contour irregularites, which often result from plication or imbrication of the SMAS, particularly when the overlying subdermal flap is very thin. Steroid injection and massage will usually alleviate these concerns.
Additionally, there are a number of named deformities that also may result from improper soft tissue manipulation. A pixie ear deformity occurs when excessive tension is placed across the skin closure inferior to the auricular lobule; in this case the lobule stretches inferiorly and creates the appearance of an elongated, attached ear lobe. Treatment may require a V to Y advancement of the lobule and re-elevation of the neck flap to decrease tension on the closure. A cobra neck deformity occurs when too much adipose tissue is removed from the central submental region without removing a commensurate volume from the lateral submentum and upper neck; this hollowing beneath the chin is reminiscent of a cobra's hood, hence the name. Fat transfer with either grafts or injections will ameliorate the problem. Lastly, the "wind-swept" look that may occur especially after deep-plane face lifting can be a result of overly aggressive lateralization of the malar fat pads or excessive tension on the cheek flaps, thereby widening the oral commissures; this is a difficult problem to repair, but it may be improved with a revision facelift performed several months later, providing enough time for tissue relaxation to permit redraping of the facial flaps without tension.
Alopecia and malposition of the hairline. This is often caused by injury to hair follicles during incision, aggressive use of electrocautery, or closure under excessive tension. Beveling the blade of the scalpel during incision, either parallel or perpendicular to the hair follicles, may minimize the appearance of the scar. Surgeons should also make patients aware of the possibility of post-surgical telogen effluvium, in which diffuse hair loss occurs approximately 3 months after surgery. This condition can be observed or treated with minoxidil, but should resolve spontaneously within 6 months. If alopecia does occur, allow 6-12 months of healing prior to hair transplantation to rule out telogen effluvium as an etiology.
When planning incisions, it is important not to disrupt the natural hairline, which can occur if attention is not paid to avoiding a stepoff of the hairline when redraping postauricular skin prior to closure. In male patients, a pre-tragal incision should be used to avoid displacing the sideburns posteriorly too close to the auricle or even onto the tragus.
First bite syndrome . This has been reported with deep plane rhytidectomy and may be a result of damage to postganglionic parasympathetic nerve fibers to the parotid gland, similar to what may occur during deep lobe parotidectomy or parapharyngeal space surgery. Aberrant reinnervation results in a painful hypercontraction of myoepithelial cells within the parotid gland at the beginning of meals; the pain usually subsides with subsequent bites. While it is unpleasant for patients, it can often be relieved with botulinum toxin injections and will generally resolve spontaneously within 6-12 months.
Patient dissatisfaction. Perhaps the most common complication is patient dissatisfaction with the surgical outcome. Approximately 30% of patients will experience depression after the face lifting, and this may require anything from reassurance to anti-depressants . It is important to consider the patient’s psychiatric history preoperatively because it may indicate a risk for postoperative depression, which can contribute to dissatisfaction with the surgical result. In some cases, dissatisfaction may be unavoidable, and many patients will require a "tuck-up" procedure within 1-2 years of the initial surgery, particularly for isolated areas of persistent or recurrent soft tissue ptosis. Ordinarily, a 5-10 year interval between facelifts is expected for maintenance of a favorable result.
Rhytidectomy is among the top 5 most common cosmetic surgical procedures, according to the American Society of Plastic Surgeons, with over 120,000 performed in 2019. It is therefore important to aesthetic surgeons to understand its history, relevant anatomy, and technical nuances. These surgeons must not only possess meticulous surgical technique, but also have excellent relationship building skills in order to achieve optimal patient outcomes.
Each facelift is an individualized procedure with its outcomes dependent on patient selection, surgical approach, and postoperative management. It is important to obtain a complete medical history and perform a thorough physical exam in order to identify appropriate candidates for the procedure. Medical comorbidities such as diabetes and hypertension or behaviors such as smoking or usage of herbal supplements can significantly increase the risk of complications. Additionally, outcomes and satisfaction are improved when a strong doctor-patient rapport and realistic expectations are established prior to the surgery.
The surgical approach depends on the patient's aesthetic goals and the effects of aging on soft tissues. Variations of rhytidectomy such as SMAS rhytidectomy, deep-plane rhytidectomy, and MACS lift address different facial subunits to varying degrees. It is also important to recognize that face lifting is only one of many treatment modalities available for facial rejuvenation. Adjuvant therapies such as blepharoplasty, cervicoplasty, liposuction, injectable treatments, and skin resurfacing should be considered at the time of surgery to provide an optimal outcome.
Lastly, postoperative care is critical; ensuring that patients follow instructions and have easy access to the surgeon or nurse in the event that complications develop will help minimize adverse effects through timely intervention.
Enhancing Healthcare Team Outcomes
Rhytidectomy is a procedure that constitutes one of the primary means by which surgeons are able to address the effects of aging on the face. As an elective aesthetic procedure, it is best approached with a coordinated healthcare team to achieve optimal results. In the preoperative phase, developing good patient rapport is critical, as this will facilitate a smoother postoperative course, particularly if complications arise. Communication and coordination with primary care providers and specialists in the management of comorbidities is also critical, as proceeding with elective surgery without minimizing cardiopulmonary risks preoperatively is unnecessarily dangerous. Likewise, smoking is known to cause poor wound healing  [Level 3], and cessation for 2-4 weeks prior to and after surgery is thought to reduce the risk of skin necrosis [Level 5]. Peri-operatively, a team effort from circulating nurses, surgical technologists, anesthesiologists, and the surgeon is required to provide high-quality surgical care. Optimal retraction from assistants can facilitate soft tissue dissection and hemostasis to avoid nerve injury and reduce anesthesia time [level 5]. The use of propofol during general anesthesia may contribute to less post-operative nausea, and together with strict control of blood pressure (<150/90 mmHg) may help reduce the risk of postoperative hematoma [level 3] .
An interdisciplinary collaborative effort is required to provide optimal patient-centered care. Risk factors for complications should be carefully minimized prior to the procedure. Communication focused on clarifying the patient's aesthetic goals and setting realistic expectations can help improve post-operative satisfaction.
