目的：了解慢性中耳炎患者鼓室成形术后耳鸣改变情况，分析慢性中耳炎患者术后听力提高程度、中耳炎分型与术后耳鸣改变的关系。方法记录106例慢性中耳炎病人术前及术后6个月的耳鸣严重程度的变化及听力改变情况，分析耳鸣改变与中耳炎分型以及听力提高的关系。使用配对t检验、独立样本t检验、卡方检验和确切概率法进行统计分析。结果慢性中耳炎患者的耳鸣发生率为46%。术前伴有耳鸣的40例病人，术后有15例病人的耳鸣治愈；18例病人耳鸣治疗有效；7例耳鸣治疗无效，鼓室成形术对耳鸣治疗有效率为82%；术后有1例新发耳鸣。术后耳鸣改善明显组的气导听力提高较耳鸣改善不良组的明显（p<0.05），中耳炎的分型对耳鸣的治疗有效性没有影响（p>0.05）。结论对慢性中耳炎伴耳鸣的患者，手术可使多数患者耳鸣缓解。其中低频气导听力的提高对其耳鸣的缓解作用较显著，鼓室成形术诱发新的耳鸣不常见。%Objective The purpose of this paper is to investigate the effect of tympanoplasty on tinnitus in patients with chronic otitis media(COM), and to determine the effect of audiologic outcome, different types of chronic otitis media influenc-ing on tinnitus changes. Methods Our study consisted of 106 patients who were operated between March 2012 and January 2013. Audiologic evaluation by pure tone audiometry and assessment of tinnitus scores were conducted 3 months before and after surgery. We analysed the data with Paired t test, Student’s t test and Fisher's exact test by stata software. Results The pre-operative incidence of tinnitus in patients with chronic otitis media was 46%. After tympanoplasty, tinnitus reduced in 82%of patients. There was a very significant difference between audiological gain and reduced tinnitus scores (p<0.05), there was no significant effect of type of COM or duration of tinnitus symptoms on the reduced tinnitus scores (p>0.05). There was one patient having new tinnitus after surgery. Conclusions Following tympanoplasty, most patients experienced a reduction in tinnitus and restored hearing. Tympanoplasty was a positive treatment on tinnitus in patients with COM.
