本文描述一种使永久性的面瘫得以支持和赋予生机的方法。作者决定采用嚼肌的运动神经(嚼肌神经)和面神经的下行分枝相吻合。尸体解剖证明,三叉神经的运动分支自颅内穿出卵圆孔后,越过翼外肌的侧面,穿过乙状切迹,在嚼肌起端附近进入嚼肌后份的表面。通过尸解,证实该神经具有合适的大小、相对不变的位置和有足够的长度以利吻合。操作方法是在全麻下,作一长而垂直的耳前切口暴露颧弓后份,仔细地将嚼肌后份的一半,自颧弓的骨面上解剖出来,此时在穿过乙状切迹的出口处,甚易暴露嚼肌神经和来自颌内动脉的伴随血管。此神经可能有
This article describes a way to support and energize permanent facial paralysis. The authors decided to use the motor nerve of the chewing muscle (the chewing muscle nerve) to coincide with the descending branch of the facial nerve. Autopsy demonstrated that the trigeminal nerve branches out of the cranial foramen ovale through the foramen ovale, across the lateral wing of the pterygoid, through the sigmoid notch and into the posterior surface of the chewing muscle near the beginning of the chewing muscle. By autopsy, it was confirmed that the nerve was of a suitable size, relatively unchanged in position and of sufficient length to facilitate anastomosis. Method of operation is under general anesthesia for a long and vertical ear before incision exposed zygomatic arch, carefully after the half of the masseter muscle, the zygomatic arch from the bone surface dissected out at this time through the sigmoid At the exit of the notch, the masseter nerve and the accompanying blood vessels from the internal carotid artery are easily exposed. This nerve may have
