在34侧成人尸体上,观察测量了肩胛提肌的形态、血供和神经支配。测得肌前缘长12.9cm;后缘长13.8cm。肌的血供:上1/2主要来自颈升动脉的分支,下1/2来自颈横动脉和颈浅动脉的分支。神经来自颈神经2～5前支的分支。根据观察结果我们认为肩胛提肌瓣移位修复口底缺损或在颈部行放射治疗时用来复盖颈部大血管等术中,是一块较为理想的供肌。 On the 34 adult corpses, the morphology, blood supply and innervation of the levator scapulae were observed. Measured muscle front 12.9cm long; trailing edge 13.8cm long. Muscle blood supply: upper 1/2 mainly from the branch of the ascending aorta and 1/2 from the branch of the transverse and superficial cervical arteries. Nerve from the cervical nerve 2 ~ 5 branch of the anterior branch. According to the observation, we think that scapular and levator muscle flap shift to repair the floor defect or radiotherapy in the neck to cover the neck and other large blood vessels surgery, is an ideal for muscle.
