目的：我们已经报道了保留鼓索神经（CTN）后味觉障碍的发生率高于CTN切除后，特别是在耳硬化病例中，年轻患者CTN功能的恢复率高于老年患者。方法：对1999 ~ 2002年59例单侧（42耳）或双侧（34耳）CTN切除术后2年以上的患者进行随访。年龄7 ~ 63岁，平均46.2岁，其中中耳炎63耳，粘连性中耳炎6耳，慢性中耳炎7耳。通过味觉电图（EGM）和问卷调查评估味觉功能。结果：CTN单、双侧电图阈值在术后2年仍明显升高。有趣的是，随着时间的推移，EGM无反应区域在10岁以下的患者中逐渐变小，而在中老年患者中则相同。在问卷调查中，单侧CTN切除后3-12个月（平均7.2个月）味觉障碍或舌麻木症状消失，双侧CTN切除后1-12个月（平均6.7个月）味觉障碍或舌麻木症状消失。
Objectives: We already reported that taste disturbance occurred more frequently after preservation of chorda tympani nerve (CTN) than after section of CTN, especially in cases of otosclorosis, and that younger patients showed higher recovery rate of CTN function than older ones. In the present study, we examined taste function after the section of CTN in middle ear surgery.Methods: Fifty-nine patients were followed up more than 2 years after section of CTN on unilatreral side (42 ears) or on both sides (34 ears) from 1999 to 2002. They aged from 7 to 63 years with a mean of 46.2 years, and they consisted of 63 ears of cholesteatoma, 6 ears of adhesive otitis media and 7 ears of chronic otitis media. Taste function was evaluated by electrogustometry (EGM) and questionnaire. Results: The threshold of EGM was still much elevated 2 years after surgery either in unilatreral or bilateral section of CTN. Interestingly, the area with no response of EGM became smaller in patients below 10 years old with the time, but it was the same in middle and old aged patients. In the questionnaire, symptoms of taste disturbance or tongue numbness ceased 3–12 months (mean, 7.2 months) after unilateral section of CTN and they ceased 1–12 months (mean, 6.7 months) after bilateral section of CTN.
