Gracilis muscle flap is commonly used in reconstructive surgery. The gracilis muscles of 15 formalin-fixed adult cadavers (30 cases) were dissected with 4 x loupe magnification. The most proximal pedicle of gracilis muscle was the deep branch of the medial circumflex femoral artery. It was located 60 mm from the pubic tubercle and had a diameter of 0.9 m on the average. The second pedicle was the medial circumflex femoral artery. It was the dominant pedicle in 13% of the cases. The mean diameter of the artery was 1.2 mm, and it entered the muscle 98 mm from the pubic tubercle. The third artery that nourished the muscle was deep femoral artery. It was the dominant pedicle in 87% of the cases. It had a mean diameter of 1.6 mm with a length of 54 mm. The most distant pedicles originated from the superficial femoral artery. They were present in all cases and were double in 77% of the cases. Mean diameter and length of the artery were 1.4 and 52 mm, respectively. They entered the muscle 266 mm from the pubic tubercle. These distal pedicles seem to be large enough to elevate the middle part of the muscle as a free flap.
