Most cases of facial nerve palsy are idiopathic, that is to say, Bell's palsy. A few cases are due to tumours on the facial nerve. Early diagnosis will avoid extensive tissue destruction with loss of hearing and lead to satisfactory facial reinnervation. Five cases are presented. In three, there was a significant delay in diagnosis. A facial nerve tumour generally presents as a paralysis of slow onset and the degree of paralysis often fluctuates. Diagnosis can be made in most cases by high resolution CT.
大多数面神经麻痹病例是特发性的，也就是说，是贝尔麻痹。少数病例是由面神经肿瘤引起的。早期诊断可避免听力丧失导致的广泛组织破坏，并能实现令人满意的面部神经再支配。本文介绍了5例病例。其中3例诊断存在显著延迟。面神经肿瘤通常表现为起病缓慢的麻痹，且麻痹程度常波动。大多数病例可通过高分辨率CT做出诊断。
