Objective:To improve and optimize the modified surgical strategies for patents with Simon Ⅰ and Simon Ⅱ type of gynecomastia, based on their magnetic resonance imaging (MRI) features.Methods:Clinical data of 190 patients aged 12 to 56 years (mean age 26.7±8.6) with gynecomastia who underwent modified surgeries in the Department of Plastic Surgery of Peking Union Medical College Hospital from January 2017 to January 2023 were retrospectively analyzed. The study measured breast MRI images of 44 male patients to calculate the area ratio of the glands on the transverse plane via nipple. This provided insight into the physiological structure and the tissue distribution of gynecomastia for improving the modified surgical strategies. All 190 patients were treated with enhanced liposuction and " Pull-Through and Bottom-Up" techniques. The duration of operation, amount of liposuction and amount of glandular resection, postoperative complications were recorded, and postoperative satisfaction was investigated by questionnaire surveys.Results:MRI images of the 87-side male breast showed that the average area ratio of the glands on the transverse plane via nipple was (10.9±12.5) %. The most prevalent subtype of gynecomastia was branch pattern, accounting for 46.0%. The median surgical duration of 190 patients was 95 (65-210) minutes, the median liposuction volume was 300 (50-1 400) ml, and the median glandular removal was 19.9 (1.5-157.0) g. Eighty-eight patients (46.3%) went through followed up for more than 6 months post-posterative with an overall satisfaction score of 4.68±0.53. Postoperative complications occurred in 19 sides (5.1%), and the reoperation rate was 1.3%.Conclusions:The MRI imaging of gynecomastia shows that the component of patients′ breasts are mainly fat, with a small amount of glandular tissue and the dominant subtype is branch pattern. Enhanced liposuction combined with " Pull-Through and Bottom-Up" stab incision technique can be an effective treatment for Simon grades Ⅰ and Ⅱ gynecomastia. The method results in high patient satisfaction with fewer postoperative complications.

Objective:To evaluate the differences and aesthetic meaning of stable vitiligo treatment in the face and neck region using suction blister transplantation or noncultured autologous suspension of epidermal cells.Methods:Sixty-four stable vitiligo patients (25 males and 39 females with age ranges from 10 to 46 years, average 25 years) in the face and neck region were randomly divided into two groups (32 patients in each group): one group received suction blister transplantation, while other group received noncultured autologous suspension of epidermal cells. Patients′treatment effectiveness, pigmentation and piecing deformity were evaluated in postoperative 3 months and 6 months.Results:In the postoperative 3 months and 6 months, the effectiveness of suction blister transplantation group was 68.75% (22/32) and 90.63% (29/32), respectively, while the effectiveness of noncultured autologous suspension of epidermal cells group was 59.37% (19/32) and 87.50% (28/32), respectively, in which no significant differences were found between two groups ( P>0.05). No obvious pigmentation and piecing deformity were found in noncultured autologous suspension of epidermal cells group, which were much better than the suction blister transplantation group in postoperative 3 months and 6 months. Conclusions:Both suction blister transplantation and noncultured autologous suspension of epidermal cells could bring good treatment effectiveness for patients of stable vitiligo in the face and neck region. Compared with suction blister transplantation, noncultured autologous suspension of epidermal cells could offer better aesthetic appearance.

Objective:To investigate the effect of embedded guidance technique assisted transconjunctival lower eyelid blepharoplasty.Methods:A retrospective study was conducted to include 88 patients who underwent transconjunctival blepharoplasty and tear trough deformity correction with orbital septum fat release and fixation (referred to as transconjunctival lower eyelid blepharoplasty) at the Department of Plastic and Reconstructive Surgery, Peking Union Medical College Hospital, from October 2021 to August 2022. There were 9 male patients (10.23%) and 79 female patients (88.77%), aged 22 to 51 years, with an average age of (34.42±6.17) years. The internal fixation of septum fat flap was assisted with embedded guidance technique, and the Barton grades system was used to evaluate the surgical effect, while the patient satisfaction and complications were collected.Results:The followed-up period is 6-16 months. Before operation, 35 eyes (19.89%) were classified as Barton Ⅰ, 86 eyes (48.86%) were classified as Barton Ⅱ, and 55 eyes (31.25%) were classified as Barton Ⅲ. After transconjunctival lower eyelid blepharoplasty, 151 eyes (85.80%) recovered to Barton grade 0, 22 eyes (12.50%) recovered to grade Ⅰ, 3 eyes (1.70%) recovered to grade Ⅱ, and no case was grade Barton Ⅲ. The patient satisfaction score was (9.14±1.22) points, and 78 patients (88.64%) were very satisfied. Only 6 patients (6.82%) showed mild complications, mainly including postoperative bilateral lower eyelid asymmetry (3 cases), mild bilateral orbital area ecchymosis (2 cases) and mild surface depression at internal fixation position (1 case).Conclusions:The transconjunctival lower eyelid blepharoplasty assisted by the embedded guidance technique achieves favorable results with high patient satisfaction and few complications.

The management of chronic wounds presents significant challenges, characterized by a low rate of healing and substantial impairment of patients’ quality of life, while also exerting a considerable strain on healthcare resources. Wound healing is a multifactorial and dynamic process, necessitating close monitoring of wound changes and timely, appropriate interventions. Smart bandage/dressing, an innovative approach born from interdisciplinary research, offers a new generation of wound care. It enables dynamic quantitative monitoring of wound conditions, facilitates transdermal drug release and physical mode therapeutics, and adjusts interventions in real time based on monitoring outcomes. In comparison to traditional wound dressings, smart bandages exhibit attributes such as real-time responsiveness, precision, and convenience. They not only simplify wound management but also enhance patient comfort and compliance, showcasing potential as a safe and effective new treatment modality. Smart bandages hold promise for elevating the efficiency of managing chronic wounds, reducing morbidity rates, alleviating the burden of disease, and ultimately improving patients’ quality of life. This paper summarized the recent research progress of smart bandages and provide insights into novel wound care strategies.

Improvement of the jawline contour is a key focus in lower face and neck rejuvenation treatments. Achieving a well-defined, smooth jawline is a shared goal for both patients and plastic surgeons. This article reviews recent research on age-related changes of the jawline and evaluation method, offering valuable references for jawline rejuvenation treatments.The jawline's unique anatomical position, coupled with age-related changes, involves dynamic alterations in bone, soft tissue, and skin across multiple layers, making rejuvenation of this area a complex and challenging task. In recent years, advances in imaging technologies such as two-dimensional photography, three-dimensional stereophotogrammetry, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and micro-CT have expanded the understanding of jawline anatomy and provided precise tools for analysis and evaluation.
