对不能恢复的面神经麻痹患者,作者介绍一种用咬肌神经与面神经下支吻合的方法来支持口角及恢复其活动。全麻下于耳前行长纵形切口,将咬肌后半部起端自额弓分离,从乙状切迹出口处暴露咬肌神经及其邻近的血管,咬肌神经可分成两支,向肌肉分离神经以取得足够的长度,然后自茎乳孔暴露面神经干,向末梢游离至分成上下二个分支
For patients with facial paralysis that can not be recovered, the authors describe a method of supporting the mouth angle and restoring their activity using the masseter nerve and the facial nerve anastomosis. Under general anesthesia, the longitudinal incision of the anterior horn of the ear, the posterior half of the masseter muscle from the frontal arch separation, exposed from the sigmoid notch export masseter nerve and its adjacent blood vessels, masseter nerve can be divided into two, Separation of nerves to the muscle to obtain sufficient length, and then exposed from the stem milk facial nerve trunk, free to the distal into two branches up and down
