[An analysis of electrocochleography in patients with OSAHS].

Objective:To investigate the values of electrocochleograph（ECochG）in patients with OSAHS. Method:ECochG was performed in 31 (62 ears) OSAHS patients (moderately 5 cases, severely 26 cases) and 28 healthy adults (56 ears). AP latency ，AP amplitude and SP/AP were measured and analyzed. Result:There was no difference between the two groups in SP/AP amplitude ratio（P>0.05） while both AP latency（P<0.05） and AP amplitude（P<0.05） were significantly different. Conclusion:ECochG can confirm the damage of cochlear and auditory nerve near the cochlear segment in patients with moderate to severe OSAHS.
