听神经纤维瘤手术的严重合并症之一是面瘫。除瘤体大小与术后面神经功能失调有明显关系外,其他有关因素鲜为人知。本研究是对听神经瘤患者,手术前、后作面神经功能的临床及电生理学检查,探索能否提供预示性价值。自1982年12月到1984年1月的14个月期间,对49例听神经瘤行经迷路切除术。男性13例,女性36例,平均年龄52岁(17～77岁)。瘤体均位于内耳道口外,直径5～25mm者17例,24～40mm者16例,另外16例大于40mm。术前临床检查,面部运动功能低下者9例,其中7例仔细观察方能看出,2例面部轻瘫;半侧面肌痉挛者
One of the serious complications of neurofibromatosis surgery is facial paralysis. In addition to the significant relationship between tumor size and postoperative facial nerve dysfunction, other relevant factors are rarely known. This study is a clinical and electrophysiological examination of facial nerve function in patients with acoustic neuroma before and after surgery to explore whether it can provide predictive value. During the 14 months from December 1982 to January 1984, 49 cases of acoustic neuromas were subjected to labyrinthectomy. There were 13 males and 36 females with an average age of 52 years (17-77 years old). The tumors were located outside the inner ear canal, 17 cases were 5-25mm in diameter, 16 cases were 24-40mm, and 16 cases were larger than 40mm. Preoperative clinical examination, facial motor dysfunction in 9 cases, of which 7 cases can be seen only after careful observation, 2 cases of facial paralysis; hemifacial spasm
