[The features of auditory brainstem response in patients with obstructive sleep apnea-hypopnea syndrome].
OBJECTIVE
To investigate the effects and causes of obstructive sleep apnea-hypopnea syndrome (OSAHS) on auditory pathway, the changes of auditory brainstem response (ABR) were analyzed.


METHODS
With the use of polysomnography,72 snorers were examined and divided into OSAHS and non- OSAHS groups. These two groups patients and a group of normal person were underwent ABR measuring.


RESULTS
There were statistically significant difference between the group of OSAHS and the non-OSAHS or the group of OSAHS and the normals on the delayed latency of wave I and wave V, the response liminal value of wave V rised.


CONCLUSIONS
The results suggest that cochlear function may be affected in patient with OSAHS, the effected of brain stem is unknown.
