Hemifacial spasm can be diagnosed by observation and clinical history. It is thought to arise primarily from compression of the facial nerve at the pons, usually by an adjacent artery. Although many approaches to treatment have been tried, the most effective is microvascular decompression of the facial nerve at the pons. That operation has well-recognized risks, including ipsilateral deafness. The latter complication ordinarily can be avoided by the use of intraoperative monitoring of auditory evoked potentials.
面肌痉挛可通过观察和临床病史进行诊断。一般认为其主要源于脑桥处面神经受压，通常是被邻近动脉压迫。尽管已经尝试了许多治疗方法，但最有效的是在脑桥处对面神经进行微血管减压术。该手术存在一些公认的风险，包括同侧耳聋。通过术中监测听觉诱发电位，通常可以避免后一种并发症。
