自体脂肪颗粒注射移植治疗面部软组织凹陷

目的 评价自体脂肪颗粒注射移植治疗面部软组织凹陷的效果。方法 利用吸脂术从身体其它部位皮下吸取脂肪颗粒，注射植入面部软组织凹陷部位。结果 1996年～2002年，共治疗36例(56个部位)面部软组织凹陷，其中45个部位接受1次脂肪颗粒注射，11个部位接受2次注射，每次注射量为1．5m1～24m1，平均8．9m1。在随访超过6个月的28例(43个部位)中，8个部位(18．6％)注射2次，术后6个月38个部位外形得到明显隆起的改善效果，优良率88．4％(38／43)。未见严重并发症。结论 对于较为单纯的面部软组织凹陷的患，自体脂肪颗粒注射移植是一种微创、简便、安全、有效的治疗方法，必要时需重复注射。

Treatment of facial soft tissue depression by injecting transplantation of autologous fat granules

Objective To evaluate the effect of injecting transplantation of autologous fat granules in the treatment of soft tissue depression in face. Methods Autologous subcutaneous fat granules were obtained by liposuction and implanted into the facial sites of soft tissue depression by injection. Results From 1996 to 2002, 56 affected sites were treated, in which 45 sites were given fat granule injection once and 11 sites twice. The volume of fat granules ranged from 1.5ml to 24ml with an average of 8.9ml. Among the 43 sites in 28 cases followed up for more than 6 months, including 8 sites (18.6%) treated twice, 38 ones showed excellent or good augmentation results for 6 months, the percentage being 88.4%. No serious complications occurred. Conclusions Local injecting transplantation of autologous fat granules is effective for correcting the simple soft tissue depression in face. Repeated injections may be needed in some cases. The procedure is simple, safe and minimally invasive.
