Chorda tympani nerve is a branch of the facial nerve which enables perception of taste of 2/3 anterior part of tongue and it is responsible for unilateral parasymphatetic nerve supplying of the submandibular and sublinqual salivary glands.
Prospective analysis of patients operated on middle ear in ENT Department Jagiellonian University of Krakow between 2004-2008 was performed. Nearly 650 operations were done in that period of time. Chorda tympani nerve was cut in 96 individuals. Most of them were treated for chronic otitis media.
When chorda tympani nerve was cut--the majority of cases did not complain of dysgeusia. Disturbance of taste was observed in ca. 2% of patients but it was transitory. The subject experienced sour/metallic taste.
Taste disturbance following unilateral injury to the chorda tympani nerve was usually the most intense in the first few weeks and improves with time.
鼓索神经是面神经的一个分支，它能使人感知舌前三分之二的味觉，并且负责单侧副交感神经对下颌下腺和舌下腺的支配。
对2004年至2008年期间在克拉科夫雅盖隆大学耳鼻喉科接受中耳手术的患者进行前瞻性分析。在此期间共进行了近650例手术。其中96例患者的鼓索神经被切断。他们大多数因慢性中耳炎接受治疗。
当鼓索神经被切断时，大多数患者并未主诉味觉障碍。约2%的患者出现味觉紊乱，但为暂时性的。患者会尝到酸味/金属味。
单侧鼓索神经损伤后的味觉障碍通常在最初几周最为严重，并随时间改善。
