乳房缩小术与乳房上提术后切口皮脂腺囊肿产生原因及预防

目的探讨乳房缩小整形术及乳房上提术后,切口皮脂腺囊肿的形成原因以及预防措施。方法 2004年5月至2007年5月,接受乳房缩小术及乳房上提术的患者60例,随机分为A、B两组。A组手术中去表皮厚度不超过真皮的1/3厚度,B组切除几乎全层真皮,对比两组术后出现切口皮脂腺囊肿情况。结果术后随访2～4年,A组中有4例术后出现切口皮脂腺囊肿(13.3%),B组中未出现切口皮脂腺囊肿。两组中均无病例出现乳头乳晕血运障碍。结论在乳房缩小整形术和乳房上提术中增加去表皮的厚度,可以减少术后出现切口皮脂腺囊肿的发生率,且不会影响乳头乳晕的血运。

Study of Cause and Prevention on the Sebaceous Cysts at the Incision Site after Mastopexy and Reduction Mammaplasty

Objective To investigate the cause and prevention of such sebaceous cysts.Methods Sixty patients undergoing mastopexy or reduction mammaplasty were randomly divided into two groups.Peri-areolar de-epithelialization was performed to a depth of less than one-third of the dermis in group A and nearly the full thickness of the dermis in group B,and the incidence of sebaceous cysts was compared between these two groups.Results Patients were followed-up for 2 to 4 years.In group A,sebaceous cysts at the incision site were found in 4 patients（13.3%）;however,no sebaceous cysts occurred in group B.Conclusion Increasing the thickness of de-epithelialization appears to decrease the incidence of sebaceous cysts at the incision site,which would not affect the blood supply to nipple-areola complex.
