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。

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.
