目的　探讨腋窝穿支的解剖学特征，为临床阴阜软组织缺损的修复提供带毛皮瓣。 方法　选用30侧成人尸体标本15具（30侧），通过乳胶灌注、巨微解剖等方法，重点观测：①腋窝穿支血管的起源、分支与吻合；②腋窝穿支血管的外径与长度。  结果　腋窝底部皮肤有3种穿支：①胸背动脉第1皮支：出现率96.7%，起始外径（1.2±0.3） mm；②胸外侧动脉第1皮支：出现率90%，起始外径（1.2±0.2） mm；③腋动脉直接穿支：出现率93.3%，起始外径（1.4±0.3） mm。 结论　腋窝区皮肤血供丰富，解剖恒定,至少有一条皮穿支可遴选为血管蒂设计带毛穿支皮瓣，修复因肿瘤根治术后、烧伤、创伤等原因导致的带毛区皮肤缺损。

Objective　To investigate the anatomical characteristics of the axillary fossa perforator, providing the hair-bearing perforator flap for reconstruction of the mons pubis defects.　Methods　30 sides of adult cadaveric specimens were managed by methods of red latex perfusion, macro-micro-anatomy. The following contents were observed emphatically: ①The origin, branches, and anastomosis of the axillary fossa perforators; ②The outer diameter and length of the axillary fossa perforators.　Results　There were three types of perforating vessels in the axillary region: the first cutaneous perforator of the thoracodorsal artery (occurrence rate: 96.7%), the first cutaneous perforator of the lateral thoracic artery (occurrence rate: 90%), and the direct perforator of the axillary artery (occurrence rate:93.3%), with an average original outer diameter of (1.2±0.3) mm, (1.2±0.2) mm, and (1.4±0.3) mm, respectively.　Conclusions　Due to the rich blood supply and constant anatomy, there was at least one cutaneous perforator to be taken as the vascular pedicle for the design of a hair-bearing perforator flap in this axillary region, which could be a supplementary choice for repairing the hairy skin defects caused by tumor radical resection, burns, as well as trauma and other reasons.
