15Severe 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. Eight patients with severe bilateral cleft lip and palate were treated with premaxillary osteotomy for premaxilla repo
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. METHODS: This was a retrospective study of immediate prepectoral DTI breast reconstructions p
SUMMARY: 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 measuremen
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. METHODS: This was a retrospective review of the medical records of pat
SUMMARY: 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. To minimize the risk of injury, the auth
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. Methods: This study was a retrospective review of patients who had undergone breast reconstruction operation between May 2020
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. METHODS: The patients who underwent vulvar reconstruction between April 2017 and May 2020 were retrospectively
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 gastro
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. Given the lack of knowledge of the effectiveness of ADM without the
Background Serial volumetric changes of reconstructed breasts have not been studied in detail. In this study, we analyzed serial volumetric changes of reconstructed and contralateral normal breasts during long-term follow-up, with a focus on the effect of various adjuvant therapies. Methods Among all patients who underwent immediate breast reconstruction with a unilateral pedicled transverse rectus abdominis musculocutaneous (p-TRAM) flap, 42 patients with valid data from 3 postoperative positro
Although many studies reported the safety and efficacy of high-intensity focused ultrasound (HIFU) therapy, there are still worries about internal organ injury. However, reports of abdominal wall hernias after HIFU therapy are rare. We present three cases of abdominal wall hernias without skin injury after HIFU therapy in uterine adenomyosis or fibroids. The diagnosis was often delayed because of vague symptoms, inadequate clinical suspicion, and delayed proper image studies. Abdominal wall hern
