The aim of this study was to clearly identify the vascularization of the pectoralis major myocutaneous flap owing to the importance of its use in the surgery of cervicofacial cancer. This work was based on the study of 40 pectoralis major muscles. The anatomical specimens were dissected after non selective injection of red latex followed by selective injection via the arterial pedicle of the muscle and finally injection of the cutaneous territory supplied by this pedicle. This study confirms the existence of a main arteriovenous pedicle vascularizing the donor site. The pedicle, lying at the deep surface of the pectoralis major, originates from the thoracoacromial artery. Rotation of the myocutaneous flap is achieved around this pedicle, the latter ensuring the survival of the flap. Participation of other arteries in the vascularization of the pectoralis major myocutaneous flap was also noted in this study.
由于胸大肌肌皮瓣在颌面癌手术中的应用具有重要性，本研究旨在明确其血管分布情况。这项工作基于对40块胸大肌的研究。解剖标本在非选择性注入红色乳胶后，通过肌肉的动脉蒂进行选择性注入，最后注入该蒂所供应的皮肤区域。本研究证实存在一条主要的动静脉蒂为供区供血。该蒂位于胸大肌的深面，起源于胸肩峰动脉。肌皮瓣围绕此蒂旋转，该蒂确保了皮瓣的存活。本研究还注意到其他动脉参与了胸大肌肌皮瓣的血管形成。
