Loss of taste function was studied pre- and postoperatively in patients who underwent myringoplasty.
Thirty-two patients who were diagnosed with chronic otitis media and underwent myringoplasty between May 2007 and May 2009 were included in the study. Regional taste test was performed preoperatively and two weeks after the operation in all patients planned to undergo myringoplasty. For patients describing disturbance in the postoperative taste test or in the questionnaire form, the taste test was repeated at six months after the operation and the questionnaire form was completed.
Chorda tympani was preserved in 18 patients (56.2%), traumatized in nine patients (28.1%), and cut completely in five patients (15.7%). Totally in 10 out of 32 patients (31.2%), an disturbance in the taste test was found at two weeks postoperatively. Sweetness/saltiness, bitterness, and sourness taste disturbances were found in 10, nine, and two patients, respectively. Improvements were identified in two out of 10 patients in the taste test performed at six months. The disturbances in the taste tests of eight patients continued to exist at that time. Sweetness/saltiness, bitterness, and sourness taste disturbances were found in eight, seven and two patients, respectively.
The chorda tympani nerve may be traumatized or completely cut as a complication of ear surgery. Sacrificing the nerve, where it is highly traumatized by surgical devices, reduces the duration of postoperative complaints.
对接受鼓膜成形术的患者术前及术后的味觉功能丧失情况进行研究。
本研究纳入了2007年5月至2009年5月间被诊断为慢性中耳炎并接受鼓膜成形术的32例患者。对所有计划接受鼓膜成形术的患者在术前及术后两周进行区域味觉测试。对于术后味觉测试或问卷中描述有异常的患者，在术后6个月重复味觉测试并完成问卷。
18例患者（56.2%）的鼓索神经得以保留，9例患者（28.1%）的鼓索神经受到创伤，5例患者（15.7%）的鼓索神经被完全切断。32例患者中共有10例（31.2%）在术后两周发现味觉测试异常。分别有10例、9例和2例患者出现甜味/咸味、苦味和酸味味觉异常。在6个月时进行的味觉测试中，10例患者中有2例有所改善。此时，8例患者的味觉测试异常仍持续存在。分别有8例、7例和2例患者出现甜味/咸味、苦味和酸味味觉异常。
鼓索神经可能因耳部手术并发症而受到创伤或被完全切断。在神经受到手术器械严重创伤的情况下牺牲该神经，可缩短术后不适的持续时间。
