Objective：To investigate the efficacy of different incising and dressing styles of minimally invasive surgery for axillary osmidrosis and their effects on complications. Methods：Totally 124 patients with axillary osmidmsis（245 sides） undergoing different minimally invasive surgeries were analyzed and were randomly divided into three groups. Three incising styles of and three dressing styles were performed on patients in the three groups respectively and clinical efficacy as well as short and long term complication incidences were compared. Incising styles included bilateral ‘W’ shape incision，unilaterally ‘W’ shape incision on the inferior border and vertical incision through the axilla center. The dressing styles included ‘six points’ suturing dressing，multi-poles rubber drainage dressing and ‘rivet-type’ fixing and compressing dressing. Results：Axillary sweating and hair growth were reduced in all patients. No statistical significance in clinical efficacy was observed among different styles of incising and dressing（P ＞0.05）. Postoperative com－plication incidences were 17.14% in short term and 14.29% in long term. Postoperative complication incidences in short and long term were lower in bilateral ‘W’ shape incision than in the other two incising styles（P<0.05）. Postoperative complication incidence in short term was lower in multi-poles rubber drainage dressing than in the other two dressing styles（P<0.05），but no difference was observed in long term among the three styles（P >0.05）. Interactive effects of different incising and dressing styles on short and long term complications were not verified. Conclusions：There was no significant difference in clinical efficacy among three incising and dressing styles. Bilateral ‘W’ shape incision can reduce the short and long term complications and multi-poles rubber drainage dress－ing can reduce short term complication but has no effect on long term complication.
