听神经瘤是仅次于神经胶质瘤和脑膜瘤的颅内第三常见肿瘤,占全部颅内肿瘤的9％,桥脑小脑角肿瘤的70～80％,此瘤一般生长缓慢,有的病人于生前没有症状,所以有“沉默型”或“无症状型”听神经病之称。据Bell,Schoknecht及美国全国技术情报组织的报导,此瘤在尸检中的发现率为1.3～2.4％。本文通过1062例颞骨标本检查,结合死者的临床病历记录,分析此瘤的来源,好发部位,症状和内耳受损的机制,并对所谓“沉默型”提出早期诊断的问题。对于此瘤在治疗上 Acoustic neuroma is the second most common intracranial tumor of glioma and meningioma, accounting for 9% of all intracranial tumors and 70-80% of pontine cerebellar angle tumors. The tumors generally grow slowly, and some patients There are no symptoms in life, so there is “silent” or “asymptomatic” known as neuropathy. According to reports by Bell, Schoknecht and the National Intelligence Service of the United States, the tumor was found to have an autopsy rate of 1.3-2.4%. In this paper, 1062 cases of temporal bone specimen examination combined with the records of the deceased clinical records, analysis of the source of the tumor, the location of the hair, symptoms and damage to the inner ear mechanism, and the so-called “silent type” proposed early diagnosis. For this tumor in the treatment
