耳聋伴耳鸣患者助听器选配模式与耳鸣掩蔽效果的比较

摘要

目的 通过比较双耳聋伴耳鸣患者在单、双耳助听器选配模式下对耳鸣的掩蔽疗效,探究助听器选配模式对耳鸣掩蔽作用的临床意义.方法 对20例病程在1年以上的双耳感音神经性耳聋且伴有双耳耳鸣的患者,分别记录未助听、单耳助听及双耳助听1个月后的耳鸣强度、频率匹配结果及耳鸣残疾评估量表(tinnitus handicap inventory,THI)得分,并进行统计分析.结果 受试者在未助听、单、双耳助听1个月后耳鸣频率无变化,耳鸣强度依次为9.47±3.02,9.00±4.05,8.60±5.53 dB,三种模式下耳鸣响度之间差异均无统计学意义(P＞0.05);THI量表得分依次为58.93±19.72,41.33±23.14,24.67±17.59,三种模式的THI得分之间差异均有统计学意义(P＜0.05).结论 双耳配戴助听器较单耳虽对耳鸣程度上无法起到缓解作用,但是可以获得较好的主观感受.%Objective By comparing the Patients who has hearing loss and tinnitus fit different hearing aid modes for masking tinnitus.To explore the clinical significance of wearing hearing aids for tinnitus masking effect.Methods 20 cases of bilateral sensorineural hearing loss for more than one year are included,accompanied by bilateral tinnitus.The records consisted of tinnitus intensity,frequency matching results and Tinnitus Handicap Inventory scores in unaided,or aided in one or two ears for a month.The data of Tinnitus frequency,intensity,THI scores were analyzed.Results There were no changes to the tinnitus frequencies,but the loudness scores were 9.47±3.02,9.00±4.05,and 8.60±5.53 dB under the unaided,unilaterally and bilaterally aided conditions.There were no statistically significant differences (P＞0.05).THI scores were 58.93±19.72,41.33±23.14,and 24.67±17.59 under the three conditions.The THI scores were statistically different(P＜0.05).Conclusion Binaural hearing aids have a better effect on masking tinnitus than unilateral amplification.
