目的探讨持续性耳鸣患者听力临床特征。方法 125例耳鸣患者,根据患者耳鸣类型分为A组(持续性耳鸣,75例)和B组(间断性耳鸣,50例),比较两组患者年龄、性别、病程、耳鸣部位、伴随症状及听力情况。结果两组患者性别、年龄及病程比较差异无统计学意义(P>0.05)。A组患者左耳耳鸣发生率56.00%高于B组的34.00%,右耳耳鸣发生率16.00%低于B组的42.00%,差异具有统计学意义(P<0.05);两组患者双耳耳鸣发生率比较差异无统计学意义(P>0.05)。A组患者耳鸣伴随症状发生率40.00%高于B组的16.00%,差异具有统计学意义(P<0.05);但两组耳鸣不同伴随症状比较差异无统计学意义(P>0.05)。不同频率(0.5、1.0、2.0、4.0 k Hz)下A组患者听力水平低于B组,差异有统计学意义(t=7.6347、5.1336、3.3038、3.0879,P<0.05)。结论持续性耳鸣好发于左耳,常合并有不同类型伴随症状,对患者听力造成一定影响。
Objective To investigate the clinical features of hearing in patients with persistent tinnitus. Methods A total of 125 patients with tinnitus were divided into group A (n = 75) and group B (n = 50) according to their tinnitus. Age, sex, course of disease, tinnitus, concomitant symptoms, Listening situation. Results There was no significant difference in gender, age and duration between the two groups (P> 0.05). The incidence of left ear tinnitus in group A was 56.00% higher than that in group B 34.00%, the incidence of right ear tinnitus 16.00% was lower than that in group B 42.00%, the difference was statistically significant (P <0.05) The incidence was no significant difference (P> 0.05). The incidence of tinnitus accompanying symptoms in group A was higher than that in group B (40.00%, 40.00%) (P <0.05). However, there was no significant difference in tinnitus between the two groups (P> 0.05). The hearing ability of patients in group A at different frequencies (0.5,1.0,2.0,4.0 k Hz) was lower than that in group B (t = 7.6347,5.1336,3.3038,3.0879, P <0.05). Conclusions Persistent tinnitus occurs predominantly in the left ear, often accompanied by different types of accompanying symptoms, which may affect hearing ability of patients.
