目的:探讨自体乳腺组织重构双环法在乳房下垂矫正应用的可行性及效果。方法:2016年1月至2018年12月，中山大学孙逸仙纪念医院整形外科共收治25例(年龄18～53岁；平均35岁)要求矫正乳房下垂的患者，均行自体组织重构双环法矫正，乳腺组织量过剩患者切除过剩的乳腺组织后进行重构，对于乳房下垂乳腺组织量适中或不足的患者进行乳腺组织瓣游离后自体乳腺组织重塑收紧。于术后6个月随访其乳房对称性、形态、大小、切口瘢痕。结果:术后1例右侧乳房皮下积液，经引流后愈合；3例乳晕伤口部分裂开，再次缝合后愈合；所有患者患者乳头乳晕血运良好，无坏死，术后乳房下垂得到明显矫正，外形满意，瘢痕增生不明显，初期荷包缝合的皱褶1个月后基本消退，平整。6个月随访，术后切口瘢痕隐蔽，外形良好。结论:自体组织重构双环法矫正乳房下垂是安全有效的方法。“,”Objective:To explore the feasibility and effect of autologous tissue reconstruction 'double ring method' in the correction of breast ptosis.Methods:From January 2016 to December 2018, a total of 25 patients (aged 18-53 years, with average age of 35 years) were admitted to the Plastic Surgery Department of Sun Yat-sen Memorial Hospital of Sun Yat-sen University. Patients requiring correction of breast ptosis were all treated with autologous tissue reconstruction 'double ring method'. Patients with excessive breast tissue were treated with reconstruction after removal of excess breast tissue, and patients with moderate or insufficient breast tissue were treated with remodeling and tightening of autologous breast tissue after free breast tissue flap. The breast symmetry, shape, size and incision scar were followed up 6 months after the operation.Results:One case of right breast subcutaneous fluid was healed by drainage. 3 cases of areolar wound were partially split and healed after re-suture. All patients had good blood circulation of nipples and areola without necrosis, and the postoperative breast ptosis was significantly corrected with satisfactory appearance and without obvious scar hyperplasia. The folds of initial purse suture basically subsided and smoothed after 1 month. After 6 months follow-up, the incision scar was concealed and the shape was good.Conclusions:Autologous tissue reconstruction 'double ring method' is a safe and effective method to correct breast ptosis.
