Background: Multiple intrinsic and extrinsic factors influence aging and lead to visible changes in the skin, including dryness, fine lines and wrinkles, loss of elasticity, surface roughness, uneven pigmentation, and loss of luminosity. Although it is well established that a single combination of topicals can address multiple signs of skin aging, it is common for patients' at-home skin treatment routines to include multiple different topicals with different active ingredients. The layering of active ingredients can cause skin irritation, and lead to noncompliance with a consistent routine. Further, multiple active ingredients may exacerbate irritation from in-office aesthetic treatments.

Objectives: To assess the long-term efficacy, safety, tolerability, and patient adherence to a Stackable Treatment topical routine consisting of 4 complementary topical formulations.

Methods: This study examined a daily topical routine (Stackable Treatment routine) consisting of 4 topical formulas with different active ingredients, and evaluated the routine's safety, tolerability, and efficacy in a composite of in-office treatment patients who applied the routine for a minimum of 1 year.

Results: Of the 14 patients, 0 experienced adverse reactions. Improvements to multiple skin parameters were observed, including improvements to skin hydration, surface texture, pigmentation, vasculature, and the appearance of scars. The majority of patients continue to use the Stackable Treatment routine after the study's conclusion.

Conclusions: The combination of low incidence of irritation, high patient satisfaction, and overall efficacy of the routine indicates the Stackable Treatment routine may be well suited as a foundational skin care regimen that can complement in-office aesthetic treatments.

Background: Surgeons and providers in aesthetic medicine seek noninvasive devices that can be utilized for safe, efficient, and effective body contouring. Patient demand has propelled the development of novel devices that can simultaneously improve skin laxity, adipolysis along with stimulation of muscle hypertrophy.

Objectives: To determine the efficacy of body contouring after 3 treatments using the noninvasive Transform (InMode, Lake Forest, CA) device.

Methods: A prospective, multicenter study was performed. Outcomes evaluated include: standardized caliper and ultrasound measurements of abdominal skin/soft-tissue thickness, waist circumference, histologic evaluation, patient comfort, and satisfaction assessments.

Results: Forty-four patients were successfully enrolled in the study and completed the series of 3 treatments which involved combined electrical muscle stimulation (EMS) and noninvasive bipolar radiofrequency (RF). Abdominal ultrasound measurements reveal a decrease in soft-tissue thickness (average 3.1 mm; P = .001), there was a significant decrease in caliper measurements of periumbilical skin thickness (P < .003), and the average reduction of abdominal circumference was 1.9 cm (P < .0001) 3 months after the treatment series. Histology confirmed subcutaneous adipolysis without damaging the dermal layer. Patients reported a high degree of satisfaction with the overall result (P = .003) and that each of the 3 treatments were progressively more comfortable (P < .005).

Conclusions: This study demonstrates that a series of simultaneous noninvasive RF with EMS treatments to the abdomen decreases subcutaneous soft-tissue thickness of the treated area. These comfortable treatments ultimately result in a high degree of patient satisfaction at 3 months.

Background: Minimally invasive beaded electrosurgical dissectors ("BEED devices") provide simultaneous sharp dissection, blunt dissection, and electrosurgical coagulation while performing 100 cm² porcine tissue plane dissections in 0.8 to 3 min with minimal bleeding and no perforations.

Objectives: The aim of the study was to report the basic science and potential clinical applications and to video document the speed and quality of planar dissections in in vivo and ex vivo porcine models with thermal damage quantified by thermal and histopathologic measurements. Additionally, in vivo porcine specimens were followed for 90 days to show whether adverse events occurred on a gross or macroscopic basis, as evidenced by photography, videography, physical examination, and dual ultrasonography.

Methods: Ex vivo porcine models were subjected to 20, 30, and 50 W in single-stroke passages with BEED dissectors (granted FDA 510(k) clearance (K233002)) with multichannel thermocouple, 3 s delay recordation combined with matching hematoxylin and eosin (H&E) histopathology. In vivo porcine models were subjected to eight 10 × 10 cm dissections in each of 2 subjects at 20, 30, and 50 W and evaluated periodically until 90 days, wherein histopathology for H&E, collagen, and elastin was taken plus standard and Doppler ultrasounds prior to euthanasia.

Results: Five to 8 mm width dissectors were passed at 1 to 2 cm/s in ex vivo models (1-10 cm/s in vivo models) with an average temperature rise of 5°C at 50 W. Clinically evidenced seromas occurred in the undressed, unprotected wounds, and resolved well prior to 90 days, as documented by ultrasounds and histopathology.

Conclusions: In vivo and ex vivo models demonstrated thermal values that were below levels known to damage subcutaneous adipose tissue or skin. Tissue histopathology confirmed healing parameters while Doppler ultrasound demonstrated normal blood flow in posttreatment tissues.

Background: Breast augmentation with implants recorded over 1.6 billion procedures globally in 2022. To reduce surgical trauma and complications and facilitate a fast recovery, we employ an ultrasound-guided local-regional anesthesia technique, the creation of a partial submuscular implant pocket by direct endoscopic visualization and minimal skin access on the mammary fold.

Objectives: The aim in this study is to evaluate whether breast augmentation performed in endoscopy under local-regional anesthesia reduces postoperative recovery time, reduces complications, and increases patient satisfaction.

Methods: Patients provided their consent through a signed form. We set strict inclusion and exclusion criteria. We prospectively evaluated postoperative pain and recovery times, the rate of complications, and patient satisfaction at 12 months postsurgery.

Results: Between January 2021 and September 2022, 200 patients met the inclusion criteria. The average operation time was 54.2 min. Patients were discharged from the hospital within 2 to 3 h. Eighty-nine percent of patients expressed great satisfaction with the result. None of the patients experienced postsurgical complications.

Conclusions: In our initial study, we showed that endoscopic breast augmentation conducted under localized anesthesia is safe. It allows for quick recovery postsurgery and swift resumption of everyday activities. The overall complication risk is less than what has been reported in scientific studies for the classic dual-plane technique. Moreover, this approach yields excellent patient satisfaction. Additional prospective and randomized studies will be required to enhance the scientific validity of this technique. Moreover, a larger patient cohort will be essential to stratify the risks associated with varying prosthetic volumes.

Background: In the buttocks and thighs, skin quality, focal adiposity, volume deficiency, skin laxity, and/or textural issues each contribute to overall appearance. For patients undergoing rejuvenation/beautification procedures, global improvement is desired, making multimodal treatment the standard of care to address these mechanistically distinct concerns. Resolution of cellulite depressions is central to patient satisfaction and aesthetic outcomes: without management, the overall aesthetic suffers, and patients are left partially unsatisfied with treatment results. With minimally invasive Targeted Verifiable Subcision (TVS; Avéli [Revelle Aesthetics, Inc., Mountain View, CA]), septa with a confirmed role in dimple formation can be released through mechanically verified subcision, permitting consistent outcomes.

Objectives: Discuss the application of TVS as part of a multimodal approach to buttock and thigh rejuvenation and share best practices for obtaining optimal improvement.

Methods: A group of 6 experts in aesthetic plastic surgery and dermatology convened for a 2 h roundtable discussion of select case studies, best practices, and their approaches for obtaining optimal outcomes in clinical practice.

Results: Clinical cases from 6 patients who presented for buttock and/or thigh rejuvenation/beautification are presented where TVS was applied as part of a multimodal approach. Before and after images, details of patient cases, and a discussion of best practices for patient education and evaluation, treatment planning, technique, safety, postprocedure care, and open research questions are included.

Conclusions: TVS is emerging as a valuable tool for the treatment of cellulite in the buttocks and thighs that may potentially be used alongside surgical and nonsurgical approaches, often on the same day.

Background: Implant-based breast augmentation is a gold standard procedure for transfeminine patients to create a more feminine-appearing chest. In many cases, ancillary procedures are performed simultaneously to achieve an optimal aesthetic result.

Objectives: To determine the clinical outcomes of patients undergoing feminizing gender-affirming breast surgery in a single academic institution.

Methods: A retrospective electronic chart review of feminizing gender-affirming breast surgery patients at Mayo Clinic, Rochester, from 2017 to 2022 was conducted. Patients' demographics and surgical outcomes were gathered. A survival analysis was performed to obtain the time-to-event complication rate.

Results: Over 5 years, 46 patients (92 breasts) were included. The mean age was 39 years (standard deviation [SD] ±15), and most had an above-normal body mass index (BMI) (58.7%). Thirty (65%) had previous gender-affirming surgeries. The mean implant volume was 289 mL (SD ±95; 140-520). Most implants were placed in a subglandular plane (81%) with an inframammary fold incision (91.3%). All implants used were smooth, round cohesive silicone gel implants. Ancillary procedures were performed in 32 patients (69.57%). Eight patients presented complications (4 major vs 4 minor) in a median postoperative follow-up of 372 vs 392 days; at 1-month follow-up, the probability of a complication having occurred is 2.17% (95% CI: 0%-6.3%) vs 5% (95% CI: 0%-11.5%), and at 1 year, the probability is 10.21% (95% CI: 0%-20.9%) vs 12.5% (95% CI: 0%-23.4%), which remains the same up to 4 years.

Conclusions: Breast augmentation with implants is a safe procedure to achieve feminization of the breast with a low rate of complications.
