Abstract
BACKGROUND The literature is replete with favorable face-lift results, yet the objective facial rejuvenation outcome measures in Chinese women have remained poorly understood. OBJECTIVE The purpose of the study is to objectively evaluate the apparent age (AA) reduction in Chinese women following face-lift by artificial intelligence (AI) and objective observers. METHODS Standardized pre- and postoperative (1-year) images of 48 patients undergoing face-lift procedures were analyzed by AI to estimate AA. Additionally, 10 blinded, naive observers viewed each patient's images and assessed AA. The accuracy of AA and reduction in AA were evaluated and compared between the two methods. FACE-Q surveys were employed to measure patient-reported facial esthetic outcomes. RESULTS The AI demonstrated higher precision than the observers in age estimation, with a mean absolute error of 3.34 years and 90% Pearson correlation. AA reduction generated by AI was significantly lower than that by observers, with a mean reduction of 3.75 ± 3.93 and 4.51 ± 1.20, respectively (p < 0.05). However, both methods showed less AA reduction than patient self-appraisal (- 7.3 years). Improvements in facial rejuvenation following face-lift surgery is relevant to the patient's preoperative aging status. Patients whose pre-AA was greater than chronological age (CA) became "back to normal," while those whose pre-AA was less than CA became "turning back the clock." CONCLUSION The utilization of AI could provide objective, evidence-based data in the field of face-lift surgery. As a simple, complete, and time-sparing method, AI is expected to be routinely used in clinical trials and practice.

Abstract
ABSTRACT Aesthetic plastic surgery is a most unusual and unique subspecialty. Unlike other medical and surgical specialties driven primarily by objective medical diagnosis and outcome, aesthetic surgery is patient driven; it represents a special exercise in professional competence by adapting objective medical standards to a mostly subjective field. Given the subjectivity of facial beauty and of the projected aesthetic intervention outcome, in addition to be able to determine beauty of the final result as precisely and objectively as possible, it is also essential to be able to assess patient's satisfaction. However, lack of standardized facial measurements and clear definition of aesthetic outcome and beauty are still major obstacles preventing real change in the consultation dynamics to help better serve patients' expectations. Because of the tremendous increase in demand for all types of facial aesthetic procedures, an objective understanding of aesthetics and beauty is becoming of utmost importance. Recognition of the importance of science and evidence-based medicine is long overdue in our specialty. This study aims at identifying the most recently available evidence-based measures to quantitatively assess beauty and measure outcome of rhytidoplasty that can be useful in everyday aesthetic practice.

Abstract
BACKGROUND Patients desire facelifting procedures to look younger, refreshed, and attractive. Unfortunately, there are few objective studies assessing the success of types of facelift procedures and ancillary techniques. OBJECTIVES The authors sought to utilize convolutional neural network algorithms alongside patient-reported FACE-Q outcomes to evaluate perceived age reduction and patient satisfaction following various facelift techniques. METHODS Standardized preoperative and postoperative (1-year) images of patients who underwent facelift procedures were analyzed by 4 neural networks to estimate age reduction after surgery (n = 105). FACE-Q surveys were employed to measure patient-reported facial aesthetic outcome. We compared (1) facelift procedure type: skin-only vs superficial musculoaponeurotic system (SMAS)-plication, vs SMAS-ectomy; and (2) ancillary techniques: fat grafting (malar) vs no fat grafting. Outcomes were based on complications, estimated age-reduction, and patient satisfaction. RESULTS The neural network preoperative age accuracy score demonstrated that all neural networks were accurate in identifying our patients' ages (mean score = 100.4). SMAS-ectomy and SMAS-plication had significantly greater age-reduction (5.85 and 5.35 years, respectively) compared with skin-only (2.95 years, P < 0.05). Fat grafting compared to no fat grafting demonstrated 2.1 more years of age reduction. Facelift procedure type did not affect FACE-Q scores; however, patients who underwent fat grafting had a higher satisfaction with outcome (78.1 ± 8 vs 69 ± 6, P < 0.05) and decision to have the procedure (83.0 ± 6 vs 72 ± 9, P < 0.05). CONCLUSIONS Artificial intelligence algorithms can reliably estimate the reduction in apparent age after facelift surgery. Facelift technique, like SMAS-ectomy or SMAS-plication, and specific technique, like fat grafting, were found to enhance facelifting outcomes and patient satisfaction.

Abstract
BACKGROUND The anterior or submental necklift has been well described. Long-term results have been demonstrated in patients with minimal, mild, and moderate skin excess. It relies on the skin's unique ability to contract once separated from its attachments and further enhances the surgical result with treatment of the intermediate layer- subplatysmal fat, anterior digastric, submandibular gland, and platysma. Treatment of this layer differentiates this operation from liposuction and offers benefits beyond liposuction alone. OBJECTIVES The authors sought to assess the long-term success of the anterior necklift for neck rejuvenation and determine its utility in patients with severe cervicomental angles. METHODS This was a single-surgeon, retrospective review of patients who underwent an isolated anterior necklift with no additional procedures between 1998 and 2017. Pre- and postprocedure photographs were scrambled and examined by independent evaluators grading the change in cervicomental angle based on the Knize scale. The reduction in apparent age was calculated utilizing the validated apparent age assessment scale. RESULTS Twenty-seven patients were evaluated (42% mild and 58% moderate to severe necks preoperatively). The average follow-up was 24.7 months. There was an average 3.6-year age reduction and 1.0-grade improvement in all patients. In moderate to severe necks, there was a 3.9-year age reduction and 1.4-grade improvement in the cervicomental angle following surgery. CONCLUSIONS This study demonstrates the effectiveness of the operation in improving the cervicomental angle and reducing the overall apparent age of patients, even more so in severe cases. The operation is an option for patients who desire neck improvement but are unwilling to undergo a facelift. LEVEL OF EVIDENCE: 4

Abstract
BACKGROUND Patients desire face-lifting procedures primarily to appear younger, more refreshed, and attractive. Because there are few objective studies assessing the success of face-lift surgery, the authors used artificial intelligence, in the form of convolutional neural network algorithms alongside FACE-Q patient-reported outcomes, to evaluate perceived age reduction and patient satisfaction following face-lift surgery. METHODS Standardized preoperative and postoperative (1 year) images of 50 consecutive patients who underwent face-lift procedures (platysmaplasty, superficial musculoaponeurotic system-ectomy, cheek minimal access cranial suspension malar lift, or fat grafting) were used by four neural networks (trained to identify age based on facial features) to estimate age reduction after surgery. In addition, FACE-Q surveys were used to measure patient-reported facial aesthetic outcome. Patient satisfaction was compared to age reduction. RESULTS The neural network preoperative age accuracy score demonstrated that all four neural networks were accurate in identifying ages (mean score, 100.8). Patient self-appraisal age reduction reported a greater age reduction than neural network age reduction after a face lift (-6.7 years versus -4.3 years). FACE-Q scores demonstrated a high level of patient satisfaction for facial appearance (75.1 ± 8.1), quality of life (82.4 ± 8.3), and satisfaction with outcome (79.0 ± 6.3). Finally, there was a positive correlation between neural network age reduction and patient satisfaction. CONCLUSION Artificial intelligence algorithms can reliably estimate the reduction in apparent age after face-lift surgery; this estimated age reduction correlates with patient satisfaction.

Abstract
BACKGROUND The ability to quantitatively analyze how we look at a face and determine if this changes following facial surgery should be of interest to the plastic surgeon. Eye tracking technology (ETT) provides the ability to record where observers fixate when viewing a facial image, enabling quantitative data to be obtained comparing pre- and postoperative changes. OBJECTIVES The authors sought to investigate ETT as a novel outcome assessment tool, determining if facial rejuvenation surgery shifts attention away from the prominent signs of aging, and if so, where this attention shifts. METHODS Twenty-five volunteers viewed 32 randomized frontal, oblique, and lateral images of 11 patients pre- and post-facelift. An eye movement monitoring system recorded the observer's eye position, net dwell time, fixation count, fixation time, and revisits into predefined areas of interest. Data were grouped and analyzed by angle and areas of interest. Paired t tests were employed to detect significant differences in pre- and post-images. RESULTS On frontal images, less dwell time, fixations, and revisits were noted on the bottom third, forehead, perioral region, and neck (P < 0.05). On the lateral view, less visual attention was given to the neck, upper third, and perioral region, with more time in the cheek, nose, and middle third (P < 0.05). On oblique images, less attention was given to the neck and upper lid with more aimed at the middle third of the face (P < 0.05). CONCLUSIONS ETT provides quantitative data post-facial rejuvenation. Facial aesthetic surgery does alter where observers look when viewing a face, decreasing the time spent inspecting the prominent signs of aging.
