突发性耳聋患者耳鸣状况的危险因素研究

目的探讨突发性耳聋患者耳鸣状况的危险因素。方法收集2006年1月—2012年12月该院收治的507例突发性耳聋患者完整的病历资料,对其听力损失的程度、听力曲线的类型及治疗效果进行评定,对耳鸣响度进行分级。分析不同耳鸣程度的相关影响因素。结果 507例突发性耳聋伴耳鸣患者的耳鸣程度以3级所占的比例最大,为32.94%（167/507）;所占比例最低的为1级,为13.02%（66/507）;2、4级分别各占27.02%（137/507）。不同耳鸣程度的患者在年龄、性别、耳侧、不同听力损害程度及不同听力曲线类型等方面的分布情况相比,均无统计学差异（P〉0.05）。结论患者在年龄、性别、耳侧等方面的不同分布情况、不同听力损害程度及不同听力曲线类型等不同的突发性耳聋的听力学特征及治疗效果与耳鸣的严重程度并不存在相关性,并非造成突发性耳聋患者伴发不同严重程度耳鸣的独立的危险因素。

Risk factors of tinnitus in patients with sudden deafness

Objective To investigate risk factors of tinnitus in patients with sudden deafness. Methods Complete medical records of507 cases of sudden deafness treated at The Hospital Affiliated to Panzhihua University from January 2006 to December 2012 were collected. Their degree of hearing loss,hearing curve type and treatment were evaluated for tinnitus loudness graded. Analysis of different degrees of tinnitus related factors was made. Results Of 507 cases of sudden deafness combined with tinnitus patients＇ tinnitus degree at level three accounted for the largest proportion（32. 94%,167 /507）,that at level one accounted for the lowest proportion（13. 02%,66 /507）,and those at level two and four accounted for 27. 02%,respectively,（137 /507）. There were no statistically significant differences among patients with different degrees of tinnitus in age,gender,location of tinnitus,different degree of hearing loss,different types of hearing and other aspects of the distribution curve（P〉0. 05）. Conclusions Differences in patients＇ age,gender,location of tinnitus,different audiological characteristics,such as degree of hearing loss and different hearing curves,and treatment efficacy are not correlated with the severity of tinnitus,which are not independent risk factors of sudden deafness combined with tinnitus.
