Post-traumatic facial nerve paralysis is a common disease, but intracranial facial nerve injury after blunt injury has rarely been reported. We report a case of facial nerve avulsion at the cerebellopontine angle. A 23-year-old female with incomplete right-sided facial nerve palsy and facial spasms presented to our hospital. She had a history of traumatic injury, having fallen off a table and hit her head at the age of 2 years. After the accident, she developed complete right-sided facial nerve palsy and underwent conservative treatment with steroids. A magnetic resonance imaging examination performed 21 years later showed avulsion of the facial nerve at the cerebellopontine angle. Magnetic resonance imaging targeting the facial nerves might provide additional information to computed tomography in cases with poor recovery with conservative treatment.
创伤后面神经麻痹是一种常见疾病，但钝器伤后颅内面神经损伤鲜有报道。我们报告一例桥小脑角面神经撕脱伤病例。一名23岁女性，右侧面神经麻痹不完全伴面部痉挛，前来我院就诊。她有外伤史，2岁时从桌子上摔下头部受伤。事故发生后，她出现右侧完全性面神经麻痹，并接受了类固醇保守治疗。21年后进行的磁共振成像检查显示桥小脑角面神经撕脱。对于保守治疗恢复不佳的病例，针对面神经的磁共振成像可能比计算机断层扫描提供更多信息。
