Measurements and analysis of breast morphology changes after breast augmentation by 3D scanning

Abstract

Objective To evaluate the application of three-dimensional (3D) scanning in the measurements and analyses of breast morphology changes that occur after breast augmentation. Methods Pre- and postoperative breast 3D images were obtained in 18 patients (36 breasts) undergoing augmentation mammaplasty by 3D scanning. All implants were round sillicone and planted under pectoral muscle. Average implant volume was 232.2 mL, and average projection was 3.46 cm. The number of implants in low profile implant group was 12( h ＜ 3.0 cm), and 16 in moderate group ( 3.0 ≤ h ＜ 4.0 cm), 8 in high group ( h ≥ 4.0 cm). The following parameters were measured by Geomagic 10.0: volume, projection, angle and distance of key landmarks, and symmetry degree. Results The increased volume of breast was corresponding with the implant volume (P ＞0.05). Postoperative breast projection was 12.9 %, less than expected projection (preoperative + implant projection). The values in low, moderate, and high profile group were 5.2 %, 15.1%, and 20.2 %,respectively. Conclusion 3D scanning is a quick, convenient, accurate and non-contact method for measurement of breast morphology, and it is promising in breast plastic surgery in the future.
