面神经瘤较少见,它可发生于面神经从脑干到神经-肌肉接头处的任何部位。发生在桥小脑角(CPA)和内听道(IAC)内时,其临床表现酷似听神经瘤。面神经瘤的临床特征有赖于病变的部位和范围,尽管有急性面瘫和波动性面瘫病例的报道,但最常见的临床症状仍是缓慢的进行性面神经麻痹。感音神经性耳聋、眩晕、耳鸣可能是位于CPA和IAC内肿瘤的临床症状。此外尚有舌前2/3味觉障碍、面部抽搐、半面痉挛、眼干、口干等症状。本文报道32例面神经瘤,占同期CPA病变的2.3％。32例中18例术前诊断面神经瘤(Ⅱ
Facial neuroma is rare, it can occur in the facial nerve anywhere from the brainstem to the neuromuscular junction. Occurs in the cerebellopontine angle (CPA) and internal auditory canal (IAC), its clinical manifestations resemble acoustic neuroma. The clinical features of facial neuromas depend on the site and extent of the lesion. The most common clinical symptom is slow progressive facial paralysis, despite the reports of cases of acute facial paralysis and fluctuating facial paralysis. Sensorineural deafness, dizziness, tinnitus may be clinical symptoms of tumors located in CPA and IAC. In addition there are 2/3 before the tongue taste disorders, facial convulsions, hemifacial spasm, dry eyes, dry mouth and other symptoms. This article reports 32 cases of facial neuroma, accounting for 2.3% of CPA lesions over the same period. Preoperative diagnosis of facial neuroma in 32 cases (Ⅱ
