摘要

摘要: 目的:采用病例对照研究方法分析单侧先天性小耳畸形外耳道闭锁患者与听力正常者在安静及噪声环境中言语识别率(SDS)的差异,了解单侧外耳道闭锁患者在噪声下的言语识别结果,为临床早期干预提供科学依据。方法:单侧先天性小耳畸形合并外耳道闭锁患者(畸形组)20例,同时选取年龄完全匹配的正常受试者20例作为对照组,应用普通话言语测听材料,在声场下测试所有受试者安静及噪声环境中的SDS。结果:声场内安静条件下70 dB SPL给声,畸形组与对照组的SDS比较差异无统计学意义。信噪分离时,畸形组(言语信号在患侧、噪声在健侧)与对照组(右侧言语声刺激,左侧噪声刺激)比较差异有统计学意义(单音节、双音节、语句;S/N=0和S/N=-10)(P＜0.05);当畸形组言语信号刺激健侧、噪声刺激患侧时,两组比较差异无统计学意义。信噪同侧时,两组的单音节词的SDS差异有统计学意义(S/N=0和S/N=-5)(P＜0.05),而双音节词和语句的SDS差异无统计学意义(P>0.05)。结论:单侧先天性小耳畸形外耳道闭锁患者在噪声条件下SDS低于正常受试者。对患耳听力进行干预可提高患者噪声条件下的SDS。

Abstract: Objective: Case-control study analysis of the speech discrimination of unilateral microtia and external auditory canal atresia patients with normal hearing subjects in quiet and noisy environment.To understand the speech recognition results of patients with unilateral external auditory canal atresia and provide scientific basis for clinical early intervention.Method: Twenty patients with unilateral congenital microtia malformation combined external auditory canal atresia, 20 age matched normal subjects as control group.All subjects used Mandarin speech audiometry material, to test the speech discrimination scores(SDS)in quiet and noisy environment in sound field.Result: There's no significant difference of speech discrimination scores under the condition of quiet between two groups. There's a statistically significant difference when the speech signal in the affected side and noise in the nomalside(single syllable, double syllable, statements; S/N=0 and S/N=-10) (P<0.05).There's no significant difference of speech discrimination scores when the speech signal in the nomalside and noise in the affected side.There's a statistically significant difference in codition of the signal and noise in the same side when used one-syllable word recognition(S/N=0 and S/N=-5) (P<0.05), while double syllable word and statement has no statistically significant difference(P>0.05).Conclusion: The speech discrimination scores of unilateral congenital microtia malformation patients with external auditory canal atresia under the condition of noise is lower than the normal subjects.
