背阔肌皮瓣是修复术中最早采用的皮瓣。早在上一世纪末叶己开始应用此皮瓣于躯体和上肢的修复。Quillen等(1978)进一步用之于头颈部修复术。背阔肌是体内最大的扁平肌之一,呈扇形,起于下六胸椎、腰椎和骶椎以及髂骨嵴后部。该肌由宽渐变窄形成韧带,在大圆肌和胸大肌附着点之间,附于肱骨椎间沟。背阔肌由胸背神经所支配。它起源于第6～8颈椎,随着同名动脉分布于肌肉。此肌之感觉神经来自肋间神经。血供主要
The latissimus dorsi flap is the earliest flap to repair. As early as the end of the last century leaves have begun to apply this flap in the body and upper limbs repair. Quillen et al. (1978) further used the head and neck prosthesis. Latissimus Dorsi is one of the largest flat muscles in the body, fan-shaped, starting from the lower six thoracic vertebrae, the lumbar and sacral vertebrae, and the posterior iliac crest. The muscle is formed by a narrow gradient wide ligament, between the great circular muscle and pectoralis major attachment points, attached to the humerus intervertebral canal. Latissimus dorsi dominated by the thoracodorsal nerve. It originated in the first 6 to 8 cervical spine, with the same name artery in the muscle. The sensory nerves of this muscle come from the intercostal nerve. Blood supply mainly
