The chorda tympani is at risk of iatrogenic injury throughout its course. This paper reviews the clinical anatomy of the nerve in adults.
Systematic literature review.
Relevant English-language articles were identified using five electronic databases and one search engine. Data from approximately 70 scientific papers were supplemented with information from selected reference texts.
The anatomy of the chorda tympani differs from standard descriptions, particularly regarding its exit from the middle ear and area of lingual innervation. Whilst it is known to convey taste sensation from the anterior two-thirds of the tongue and parasympathetic innervation to the submandibular and sublingual salivary glands, the chorda tympani probably has additional sensory and secretomotor functions.
A detailed understanding of the anatomy of the chorda tympani may help to reduce the risk of iatrogenic injury during head, neck and middle-ear surgery, and to explain the variable consequences of such injury.
鼓索神经在其全程中均有遭受医源性损伤的风险。本文回顾了成人该神经的临床解剖学。

鼓索神经的解剖结构与标准描述不同,尤其是在其从中耳穿出及舌部神经支配区域方面。虽然已知其传递舌前三分之二的味觉以及支配下颌下腺和舌下腺的副交感神经,但鼓索神经可能还有其他感觉和分泌运动功能。
详细了解鼓索神经的解剖结构可能有助于降低头、颈和中耳手术中医源性损伤的风险,并解释此类损伤的不同后果。
