Abstract: 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.
