To review the currently available literature on iatrogenic injury of the adult chorda tympani.
Systematic literature review.
Five electronic databases and one search engine were used to access available English language literature on the chorda tympani, focusing on iatrogenic injury.
The chorda tympani is most often injured during middle-ear surgery, after which at least 15-22 per cent of patients experience symptoms, mostly changes in taste and dryness of the mouth. Numerous factors influence whether injury to the chorda tympani causes symptoms, including the extent of injury, type of surgery, age of the patient, anatomical variables and subjective adaptation. Although most patients experience gradual symptomatic recovery, complaints can be persistent and troublesome.
Care should be taken to preserve the chorda tympani during middle-ear surgery, and to warn patients pre-operatively about this potential complication. This is particularly important if surgery is bilateral.
回顾目前关于成人鼓索神经医源性损伤的现有文献。
系统文献综述。
使用五个电子数据库和一个搜索引擎来获取关于鼓索神经的可用英文文献，重点关注医源性损伤。
鼓索神经最常在中耳手术期间受损，术后至少15% - 22%的患者出现症状，主要是味觉改变和口干。许多因素影响鼓索神经损伤是否会引起症状，包括损伤程度、手术类型、患者年龄、解剖变量和主观适应情况。尽管大多数患者症状会逐渐恢复，但不适可能持续且令人困扰。
中耳手术期间应注意保护鼓索神经，并在术前告知患者这一潜在并发症。如果是双侧手术，这一点尤为重要。
