A randomized intraindividual comparative study evaluating the effects of two ultrasound-assisted liposuction devices on the abdomen.

BACKGROUND: Ultrasound-assisted liposuction (UAL) has become popular because of its favorable outcomes in fat emulsification, blood loss reduction, and skin tightening. This study aimed to compare the effects of two UAL devices on the abdomen by assessing postsurgery skin biomechanical properties. METHODS: This single-blind, prospective study (2020-2022) involved 13 liposuction procedures performed on patients without chronic diseases. Each patient's abdomen was divided vertically from the xiphoid to the perineum. Vibration amplification of sound energy at resonance (VASER)-assisted liposuction (Solta Medical, Inc., Hayward, CA) was performed on one half, while the other half underwent liposuction with high-frequency ultrasound energy (HEUS)-assisted technology. Skin biomechanical measurements, including distensibility, net elasticity, biological elasticity, hydration, erythema, melanin, and skin firmness, were taken at 12 and 24 months postsurgery, focusing on the anterior abdomen, 8 cm to the right and left of the umbilicus. RESULTS: Analysis of the above skin biomechanical measurements revealed no significant differences between the HEUS and VASER devices, except for skin firmness, which showed a notable increase following HEUS surgery. Patient-perceived clinical differences were assessed via nonvalidated questionnaires, revealing no distinctions between devices. CONCLUSION: Biomechanical skin results post-UAL surgery with these devices on the abdomen were not significantly different, although HEUS revealed increased skin firmness. This suggests that HEUS-assisted technology, akin to other devices, is a viable option for UAL procedures.

Cutaneous Horn Presentation in Porokeratotic Eccrine Ostial and Dermal Duct Nevus. A Brief Review and Case Report.

ABSTRACT: Porokeratotic eccrine ostial and dermal duct nevus is a rare adnexal hamartoma characterized by the presence of a cornoid lamella exclusively overlying eccrine acrosyringia. Different clinical presentations have been reported in the literature. Here, we report a case of a 6-year-old girl diagnosed with porokeratotic eccrine ostial and dermal duct nevus confirmed by histopathologic study. Atypical lesions are described as whitish, warty-looking neoformations located in the anterolateral region of the right hip (cutaneous horn).

Buccal Fat Pad Herniation, Repositioning Versus Excision: A New Algorithm of Treatment.

Background: Traumatic herniation of the buccal fat pad can be treated with repositioning or excision. This report describes a case of a child with traumatic herniation of the buccal fat pad treated with excision. A comprehensive review of the literature was performed with the objective of establishing treatment criteria for the decision-making involved in choosing between repositioning versus excision. Methods: A systematic review of the literature was performed through searches of PubMed, Ovid, Elsevier, Cochrane, ResearchGate and Google Scholar for reports published from 1968 through May 2021. The search keywords used were traumatic herniation of the buccal fat pad, buccal fat pad herniation, traumatic pseudolipoma, and traumatic lipoma. We included only those studies that included patients with intraoral buccal fat pad herniation. Results: We found and included 39 articles (44 patients). Time since trauma, size of the fat pad herniated, and presence of necrosis were the most important characteristics considered for treatment decision; on the basis of these factors, we created a treatment algorithm. We present a case report of a 2-year-old boy diagnosed with traumatic herniation of buccal fat pad and, according to our algorithm, the appropriate treatment was to perform excision. A follow-up examination at 11 months showed no complications. Conclusions: Because traumatic herniation of buccal fat pad is very rare, this algorithm can be an easy and effective tool to guide decision-making when choosing between repositioning versus excision.
