Acellular Dermal Matrix without Basement Membrane in Immediate Prepectoral Breast Reconstruction: A Randomized Controlled Trial.

Background: Acellular dermal matrix (ADM) has become popular in various reconstructive procedures of different anatomic regions. There are different needs depending on the clinical application, including breast, abdominal wall, and any other soft-tissue reconstruction. Removal of the basement membrane, which consists of collagen fibers, may help achieve natural and soft breast reconstruction, which requires highly elastic ADMs.

The Efficacy of Botulinum Toxin A Injection for Gastrocnemius Hypertrophy: A Prospective, Randomized, Double-blinded Controlled Trial.

Background: Many individuals hold an interest in aesthetic appeal, with one aspect of physical attractiveness being the alluring contour of the lower leg. Utilizing botulinum toxin A (BTX-A) injections offers several advantages, including a short procedure time, low pain, and a speedy recovery. With a demand for high-level evidence regarding the effectiveness of BTX-A injections for correction of lower leg contour, we evaluated the safety and efficacy of BTX-A injection for improvement of gastrocnemius muscle hypertrophy.

A comparison of clinical outcomes of acellular dermal matrix with and without radiation sterilization process in immediate prepectoral direct-to-implant breast reconstruction.

Background: Although there are many acellular dermal matrix (ADM) products, the sterilization process varies for each product. We compared the clinical outcomes of immediate prepectoral direct-to-implant (DTI) breast reconstruction with and without sterilization products.

Methods: This was a retrospective study of immediate prepectoral DTI breast reconstructions performed between 2018 and 2020.

Safety and Efficacy of Poly-L-Lactic Acid Filler (Gana V vs. Sculptra) Injection for Correction of the Nasolabial Fold: A Double-Blind, Non-Inferiority, Randomized, Split-Face Controlled Trial.

Background: Poly-L-lactic acid (PLLA) fillers have shown excellent results as soft tissue fillers for progressive midface volume enhancement, with long-lasting results and high patient satisfaction.

Objective: Herein, we investigated the safety and effectiveness of a new PLLA filler (Gana V) in comparison with those of the widely used Sculptra.

Methods: This double-blind, non-inferiority, randomized, split-face controlled trial was performed in France to evaluate the safety and effectiveness of injectable Gana V compared with those of Sculptra for correction of nasolabial fold (NLF) depression.

Analysis on the Difference between the Practical Brassiere Size and Real Breast Volume.

Background: Brassiere cup size is defined as the difference in chest circumference between the inframammary fold and the fullest part of the breast. However, a large number of women are not aware of the correct definition and are prone to wearing incorrectly-sized brassieres. In this report, the authors compared the cup size of worn brassieres and the actual measurement.

A Simplified Algorithmic Approach to Vulvar Reconstruction According to Various Types of Vulvar Defects.

Objective: Various surgeons adopt various vulvar reconstruction methods for different types of vulvar defects to restore anatomical structures. Vulvar reconstruction has relatively few references as it is performed in many different ways. Our report aimed to create a simplified reconstruction algorithm that can be used to select the reconstruction flap and to compare clinical outcomes.

Robot-Assisted Capsulectomy with Immediate Reimplantation in Breast Reconstruction.

Recent reports have introduced robotic breast surgery for immediate breast reconstruction with an implant. However, relevant reports of robot-assisted breast reconstruction including capsulectomy are limited. Although capsulectomy lowers risk of capsular contracture and thus contributes to better aesthetic outcomes, total capsulectomy may have complications, such as injury to axillary structures or chest wall and overlying skin devascularization.

Development of Three-Dimensional Breast Scan and Measurement Application Using Laser Imaging Detection and Ranging Sensor on iPhone.

Laser imaging detection and ranging (LiDAR) is a modern three-dimensional (3D) technology that uses a time-of-flight method based on the round-trip time of an infrared laser beam to detect the presence and features of objects. The iPhone 12 Pro is the first smart mobile device with built-in LiDAR sensors. The authors' team developed a software application based on iOS devices with built-in LiDAR sensors for 3D breast scanning and automatically analyzing the breast's geometric measurement.

A Comparative Study of Wraparound versus Anterior Coverage Placement of Acellular Dermal Matrix in Prepectoral Breast Reconstruction.

Background: Prepectoral direct-to-implant insertion (DTI) with acellular dermal matrix (ADM) is the currently preferred operation for breast reconstruction. There are different placements of ADM, which are largely classified as wraparound placement or anterior coverage placement. Because there are limited data comparing these two placements, this study aimed to compare the outcomes of these two methods.

Long-Term Serial Measurement of Muscle Volume in TRAM Flaps Using the Eclipse Treatment Planning System.

Background: Muscle flaps used in reconstructive surgery are known to lose volume over time because of denervation and disuse atrophy. However, there is currently no agreement on a quantitative approach to evaluating volume changes. Here, long-term serial measurement of muscle volume in transverse rectus abdominis musculocutaneous (TRAM) flap breast reconstruction has been conducted using the Eclipse treatment planning system.

Premaxillary Repositioning in the Severe Form of Bilateral Cleft Lip and Palate.

Severe forms of bilateral cleft lip and palate remain a challenging issue. Although nasoalveolar molding dramatically improves overall treatment success, the position of the premaxilla often remains dislocated. The authors attempted to relocate the malpositioned premaxilla into the correct position to obtain the correct three-dimensional (3D) maxillary arch structure and growth.
