Objective: To investigate the cochlear function of the patients suffering from obstructive sleep apnea-hypopnea syndrome(OSAHS) by using ABR.Methods: 40 patients with OSAHS(80 ears) admitted from February 2004 to September 2004 were divided into two subgroups: mild OSAHS group(11 cases) and moderate and severe OSAHS group(29 cases)according to the value of AHI.Each group was tested by Auditory brainstem response(ABR).The latencies of wave Ⅰ、Ⅲ、Ⅴand the interpeak latency intervals of waveⅠ-Ⅲ、Ⅲ-Ⅴ、Ⅰ-Ⅴ were measured.The obtained results of the two subgroups were respectively compared with the normal values.Results: The latencies of waveⅠ、Ⅲ、Ⅴ and the interpeak latency intervals of wave Ⅰ-Ⅲ、Ⅰ-Ⅴin the moderate and severe OSAHS subgroup were prolonged compared with the normal control values
and the difference was significant statistically.The latencies of waveⅠ、Ⅲ in the moderate and severe OSAHS subgroup were significantly prolonged compared with those in the mild OSAHS subgroup.But there was no statistical change in the latencies of wave Ⅰ、Ⅲ、Ⅴand the interpeak latency intervals of waveⅠ-Ⅲ、Ⅲ-Ⅴ、Ⅰ-Ⅴin the mild OSAHS subgroup as compared with the normal control values.Conclusion: Cochlear function can be impaired in patients with moderate and severe OSAHS
and ABR can be taken as a monitor index to observe whether OSAHS affects cochlear function or not.
