组织外扩张自体脂肪颗粒注射移植隆乳术

目的 探讨采用组织外扩张技术进行自体脂肪颗粒注射移植隆乳术的疗效及安全性.方法 进行自体脂肪颗粒注射隆乳术前,佩戴组织外Brava扩张器1个月,每天佩戴8 h,以增加乳房组织容积并改善血供.重复扩张与脂肪注射移植2～3次.结果 自2010年l～10月,采用组织外扩张自体脂肪颗粒移植隆乳术26例,获得良好隆乳效果,术后随访1个月至1年,未发现结节、硬块及囊肿等并发症.结论 以组织外扩张进行自体脂肪颗粒移植隆乳术,可以有效地增大乳房受区的容积及血管化程度,因而可以增加乳房内注射的脂肪量并提高脂肪的存活率,是一项提高自体脂肪颗粒注射隆乳效果的理想方法.

Autologous fat transfer augmentation using external tissue expansion

Objective To observe the clinical effects of autologous fat injection augmentation with external tissue expander.Methods 26 cases wore the Brava device,a bra-like vacuum-based external tissue expander for 4 weeks before autologous fat injection augmentation.Patients resumed Brava wear for 14 more days after fat injection.Results 26 women had a mean augmentation volume at 3 months of 76 ml per breast after single fat injection.Follow-up ranged from 1 month to 12 months.There were no complications such as nodules,masses,or cysts occurred.Patient satisfaction was as sessed：25 cases （95.6 %） were satisfied with the cosmetic results.Conclusions The addition of Brava expansion before autologous fat grafting leads to significantly larger breast augmentations,with more fat graft placement,higher graft survival rates,and minimal graft necrosis or complications,demonstrating high safety and efficacy for the procedure.
