【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70dB 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)(P0.05);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)(P0.05),而双音节词和语句的SDS差异无统计学意义(P0.05)。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: to analyze the difference of speech recognition rate (SDS) between patients with unilateral congenital microauricle atresia and normal hearing in quiet and noisy environment by case-control study. To understand the results of speech recognition in patients with unilateral external auditory canal atresia under noise, and to provide scientific basis for early clinical intervention. Methods: twenty patients with unilateral congenital microtia complicated with atresia of external auditory meatus (deformity group) and 20 normal subjects (age matched) were selected as control group. Testing SDS. in quiet and noisy environments for all subjects in sound field Results: there was no significant difference in SDS between the abnormal group and the control group when 70dB SPL was given under the quiet condition in the sound field. When the signal was separated, there were significant differences between the abnormal group (speech signal in the affected side, the noise in the healthy side) and the control group (right speech sound stimulation, left side noise stimulation) (monosyllabic, disyllabic, sentence). S/N=0 and S/N=-10 (P0.05); when the speech signal stimulates the contralateral side and the noise-stimulating side in the deformity group, there is no significant difference between the two groups. The SDS of monosyllabic words in the two groups was significantly different (S/N=0 and S/N=-5) (P0.05), while the SDS difference of dicyllabic words and sentences had no statistical significance (P0.05). Conclusion: the SDS of patients with unilateral congenital microauricle atresia is lower than that of normal subjects. Intervention of hearing in affected ears can improve SDS. in patients with noise
