阻塞性睡眠呼吸暂停低通气综合征的听觉功能评价

Assessment of Auditory Function in Obstructive Sleep Apnea-Hypopnea Syndrome

目的 探讨阻塞性睡眠呼吸暂停低通气综合征 (obstructivesleepapnea -hypopneasyndrome ,OSAHS)患者听觉功能有无损伤。方法 对 19例OSAHS患者及 16例正常对照者分别进行纯音测听、声导抗及听性脑干反应(ABR)检测 ,将两组结果进行统计学分析。结果 纯音听阈及声导抗测试两组无显著性差异 ;OSAHS患者ABR的波Ⅲ及波V潜伏期延长 ,两组之间有显著性差异 ;OSAHS患者ABRⅠ -Ⅲ和Ⅰ -Ⅴ波间期延长 ,两组之间有非常显著性差异。结论 OSAHS患者长期的夜间反复缺氧会导致听觉功能的损伤 ,ABR可监测OSAHS患者听觉功能的早期损害。

Objective To study the auditory function in patients suffering from obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods Pure tone audiometry, tympanometry and ABR were used to measure the auditory function in 19 patients with OSAHS and 16 patients without OSAHS. The datas were analysed between two groups by SPSS 9.0 statistic software.Results There were no differences in threshold of pure tone and tympanometry between the two groups. In ABR test showed that the lantency of wave III and wave V was longer in patients with OSAHS than that in control group .The difference was significant statistically. The interpeak lantency intervals of wave Ⅰ-Ⅲ, Ⅰ-Ⅴ in OSAHS patients were longer than that in control group .The difference was very significant statistically.Conclusion The auditory function may be affected in patients with OSAHS.ABR can be used to detect the early damage of auditory function in OSAHS.
