The palmaris brevis muscle is located in the superficial fascia of the hypothenar region. It originates from fleksor retinaculum and ulnar side of the palmar apeneurosis and ends in the ulnar part of the volar skin of the hand. In plastic surgery, the utilization of this muscle is limited when compared to palmaris longus muscle. The vascular anatomy of palmaris brevis muscle was examined in order to enlighten the possibility of the utilization of this muscle as a flap in the defects of wrist, volar side of the hand and carpal tunnel region. Ten hands of five cadavers were included in the study. The ulnar arteries were exposed and colored latex was injected through. The dissections were held under x4 loupe magnification. The branches of the ulnar artery were delineated starting from the wrist proximally and towards the proximal phalanx of the little finger distally. The diameter of the ulnar artery and the major pedicle to the palmaris brevis was measured with an electronic compass. The length of the muscle was noted in all the cadavers. The vascular anatomy of the muscle was shown microangiographically by injecting radio-opaque solution through ulnar artery after ligating the distal part of the deep palmar arc. The major pedicle of the muscle was observed 12mm (9-14mm) after the origin from the deep palmar arc, entering the muscle from the inferior surface of the muscle. There were 1-4 perforating arteries originating from the other hypothenar muscles percing the palmaris brevis muscle and nourishing the skin over the palmaris brevis muscle with a diameter of 0,4mm (+/- 0,14 mm). The diameter of the ulnar artery, deep palmar artery and the major pedicle were measured respectively as 2,2 mm (+/- 0.3), 0.8 mm (+/- 0.18), 0.37 mm (+/- 0.05). The muscle could be classified as Mathes Nahai Type V depending on the one major and multiple minor pedicles. The muscle could be used as a flap in the traumatic or infectious defects of the wrist, volar side of the hand and carpal tunnel region locally.
