Hybrid Breast Augmentation: A Reliable Formula for Preoperative Assessment of Fat Graft Volume Based on Implant Volume and Projection.

摘要: BACKGROUND Autogenous fat grafting (AFG) is an established technique used as adjunct to breast augmentation (BA) redesign shape. Surgeons often use experience and intuition estimate AFG volume, which can result in incorrect assessment of donor areas unnecessary removal. OBJECTIVES This aim this study was develop a method based on mathematical formula, utilizes implant volume projection predict volume. METHODS Thirty patients (60 breasts) underwent primary hybrid BA. A software package (SketchUp) simulate 3-dimensional volumes, turn were equation for estimating according 3 different projections. The results each group compared, via Pearson's correlation coefficient, with the clinical series. RESULTS All received Motiva Ergonomix SmoothSilk/SilkSurface implants, ranging from 175 355 cc (mean, 265 cc), well average 79.2 cc/breast (range, 50-110 cc). Twenty-nine (96.6%) either very satisfied or during mean follow-up 18 months 6-28 months). high observed between performed cohort predictions obtained formula (r = 0.938, P < 0.001). CONCLUSIONS BA procedures be estimated utilizing measurements volume/projection. low-cost applied guide surgical decision-making who are candidates LEVEL OF EVIDENCE: 4
