Abstract:
Objective:To evaluate the clinical efficacy of endoscopic-assisted dual-plane augmentation mammoplasty via abdominoplasty incision.Methods:The clinical data of patients who underwent concurrent abdominoplasty and endoscopic breast augmentation utilizing a single incision at Xi’an International Medical Center Hospital from August 2023 to February 2024 were retrospectively analyzed. Through a lower abdominal incision, a 4 cm-wide subcutaneous tunnel was endoscopically dissected in a superolateral direction from the lateral aspect of the xiphoid region, traversing the abdominal wall flap dissection area. Initially, the medial-inferior origin of the pectoralis major muscle was exposed and excised. Subsequently, the posterior space of the pectoralis major muscle was dissected to create the prosthesis space, and the rib origin of the pectoralis major muscle was severed 1 cm above the inframammary fold to establish a type Ⅰ dual-plane configuration. Depending on the patients’ breast morphology, the glandular tissue could be dissected superiorly from the surface of the pectoralis major muscle to form a type Ⅱ or type Ⅲ dual-plane. The prosthesis was then implanted, and its position was adjusted accordingly. After the drainage was placed, the remaining operation of abdominoplasty was continued. Patients’ basic information, implant volume, postoperative extubation time, and postoperative complications were recorded. A Likert scale of five points was used to evaluate preoperative and postoperative breast satisfaction [ranges from 1 to 5 points, 1 = very dissatisfied, 2 = dissatisfied, 3 = average, 4 = satisfied, 5 = very satisfied, respectively, satisfaction rate calculated as: ( "very satisfied" + "satisfied" )cases/total cases×100%]. SPSS 25.0 statistical software was used for statistical analysis. Measurement data in accordance with normal distribution were expressed as Mean±SD, and satisfaction scores not in accordance with normal distribution were expressed as M( Q1, Q3), compared by Wilcoxon rank sum test before and after operation. The count data were expressed by cases (%). Results:A cohort of 25 patients were included in the study, with a mean age of (29.8±2.9) years and a mean body mass index (BMI) of (20.8±1.7) kg/m 2. The median volume of the implanted prosthesis was (290.4±40.8) ml (range: 250-410 ml), and the mean extubation time was (3.1±0.9) d (range: 2-6 d). The mean follow-up duration was (270.0±52.4) d (range: 188-356 d). All patients demonstrated full, symmetrical, and natural breast contours. No significant complications, such as infection, hematoma, abnormal breast morphology, implant displacement, or exposure, were observed. The patient satisfaction scores significantly improved from preoperative median 1 (1, 2) to postoperative median 5 (4, 5), and the difference was statistically significant ( Z=-4.44, P<0.001). Patient satisfaction rate increased significantly from 12% (3/25) to 100% (25/25). Conclusion:Endoscopic-assisted dual-plane augmentation mammoplasty via abdominoplasty incision is a straightforward, feasible, safe, and effective procedure that eliminates breast scarring. Postoperative outcomes indicate an absence of serious complications, and patient satisfaction rates are high.
