作者在20年间对颅后窝内面神经损伤进行了40例神经吻合术。面神经损伤绝大多数是继发于听神经瘤及经迷路或颅后窝听神经瘤切除术。神经吻合术式除个别病例外都采用舌下面神经吻合术。手术指征:①完全性和不能恢复的面瘫;②面神经损伤位置在脑干与内耳道底之间;③颅外面神经功能良好;④面部肌肉活动良好;⑤供体神经功能也良好。手术方法为在局麻或全麻下作“Y”形切口,自乳突尖上2cm及腮腺后叶切开皮肤,沿胸锁乳突肌前缘弯曲向下,继而向
The authors performed 40 neurological anastomoses on the posterior fossa of the facial nerve during 20 years. The vast majority of facial nerve injury is secondary to acoustic neuroma and labyrinthine or posterior fossa acoustic neuroma resection. Neurological anastomosis except in a few cases are used under the tongue of nerve anastomosis. Surgical indications: ① complete and can not be restored facial paralysis; ② facial nerve injury location between the brainstem and the inner ear canal; ③ extracranial nerve function is good; ④ facial muscle activity is good; ⑤ donor nerve function is also good. Surgical methods for under local anesthesia or general anesthesia for “Y” shaped incision, 2cm from the mastoid tip and the parotid gland posterior lobe cut the skin, along the leading edge of the sternocleidomastoid flexion down, and then to
