    Patterns in Academic Cosmetic Surgery Practice: Population Differences and Procedure Preferences. Annals of plastic surgery PURPOSE:Although growth in cosmetic surgery remains constant in the private setting, academic cosmetic surgery practices are often underdeveloped. Our study aims to determine which patient populations access academic cosmetic surgery services. METHODS:The 2018 Health Care Utilization Project Nationwide Ambulatory Surgery Sample database was used for data analysis. Encounters for the following American Society of Plastic Surgery top 5 procedures for 2020 were selected: blepharoplasty, breast augmentation, liposuction, rhinoplasty, and rhytidectomy. Patient encounter data were collected because it relates to median income, geographic location, and primary payer status. RESULTS:The 2018 Nationwide Ambulatory Surgery Sample data set contained 44,078 encounters at academic surgical centers for the procedures listed previously. Low-income patients account for 13.7% of academic cosmetic surgery encounters compared with 37.9% for high-income patients. Breast augmentation rates are higher among low-income patients (20.5% vs 17.2%, P < 0.001), and high-income patients undergo rhytidectomy more frequently (5.7% vs 3.0%, P < 0.001). In the academic setting, patients from large metropolitan areas encompass the majority of cosmetic encounters (71.0%), and these patients are more likely to proceed with rhinoplasty, rhytidectomy, and liposuction procedures (P < 0.001). Patients from smaller metropolitan areas undergo blepharoplasty more frequently compared with those from larger metropolitan areas (56.4% vs 41.8%, P < 0.001). Self-pay and privately insured patients comprise the majority of academic cosmetic surgery encounters (40.8% and 29.9%, respectively). Eighty-eight percent of Medicare patients within this cohort underwent blepharoplasty, whereas self-pay patients accessed breast augmentation, liposuction, and rhytidectomy more often than other insured patients. CONCLUSIONS:Income status, patient location, and primary payer status play an important role in academic cosmetic surgery access rates and procedure preferences. Academic cosmetic practices can use these insights to tailor their services to the populations they serve. 10.1097/SAP.0000000000003159
    Direct Browlift. Clinics in plastic surgery Direct browlifting comprises various techniques to lift the brows using incisions on or around the brows. The classic direct browlift involves removing an ellipse of skin and subcutaneous tissue within or just above the brow cilia. However, the technique can be modified to address only lateral brow ptosis, to place the incision in the midforehead or the eyelid crease, and to place the incisions in different areas during bilateral surgery to attempt to improve symmetry. Careful attention to incision location, closure technique, and use of postoperative therapies can allow for nearly invisible scars in some cases. 10.1016/j.cps.2022.03.002
    Endoscopic Brow Lift. Clinics in plastic surgery This article discusses the physiology of brow ptosis and compares how depressor muscle alteration combined with wide subperiosteal undermining leads to its correction. A detailed description and a series of videos illustrate the endoscopic technique. Long-term before and after photographs demonstrate the efficacy of the procedure. Pitfalls and flaws in technique leading to less-than-ideal outcomes are described. 10.1016/j.cps.2022.02.003
    Incorporating the Osseous Genioplasty Into Rejuvenation of the Lower Face. Aesthetic surgery journal BACKGROUND:The chin plays a critical role in the shape, projection, and soft tissue support of the lower face. Osseous genioplasty is a powerful tool in facial rejuvenation as it allows for optimal control of the resulting chin dimensions and improvement in submental and submandibular laxity. Osseous genioplasty can be used alone or in combination with other facial rejuvenation procedures to achieve an optimal result. OBJECTIVES:We present the senior author's approach to skeletal analysis of the lower facial third and propose an algorithm that can be used to optimize skeletal support of the overlying soft tissue laxity while maintaining aesthetic facial shape and proportion of the chin. METHODS:All patients undergoing cosmetic osseous genioplasty for soft tissue rejuvenation of the lower face and/or perioral region with the senior author between 2010-2021 were retrospectively reviewed. Complications including infection, numbness, prolonged ecchymosis were recorded. RESULTS:A total of 37 patients underwent cosmetic osseous genioplasty. The average age of the cohort was 44.5 years. Twenty-six patients (70.3%) were female. Eleven patients (29.7%) underwent genioplasty alone. In addition to genioplasty, eight patients (21.6%) underwent orthognathic surgery, five patients (13.5%) underwent platysmaplasty and liposuction, and two patients (5.4%) underwent facelift. The authors propose an algorithm to guide evaluation of the lower facial third to help determine the possible role of osseous genioplasty for facial rejuvenation based on each patient's unique facial characteristics. CONCLUSIONS:In properly selected patients, osseous genioplasty can improve lower facial projection, submandibular laxity, and perioral soft tissue support while also optimizing facial shape and proportion. 10.1093/asj/sjac160
    High-Frequency Ultrasound of Facial Filler Materials in the Nasolabial Groove. Aesthetic plastic surgery BACKGROUND:Various dermal fillers are often used for nasolabial groove filling. High-frequency ultrasonography might be a valuable tool for assessing facial filler materials. METHODS:The facial ultrasound images of plastic surgery hospital of the Chinese Academy of Medical Sciences from November 2014 to November 2021 were analyzed and judged. RESULTS:A total of 94 patients who underwent high-frequency ultrasound with a nasolabial groove filler were included in the study. Hyaluronic acid was detected in 35 cases, polyacrylamide in 34 cases, lipofilling in 10 cases, silicon oil in seven cases, calcium hydroxyapatite in six cases, and silicone implant in two cases. The ultrasonic performance of hyaluronic acid was divided into four types: aggregation, diffusion, mixed pattern, and associated infection; of polyacrylamide was divided into five types: aggregation and inclusion, aggregation and non-inclusion, diffusion, mixed pattern, and associated infection; and of lipofilling was divided into four types: aggregation, diffusion, fat liquefaction necrosis, and cystic change. Echo intensity, echo characteristics, boundary clarity, fluidity, and blood flow signals can be used as the basis for identifying filler materials. CONCLUSION:High-frequency ultrasound has an identification significance for the filling materials in the area of nasolabial groove.
