title: [The features of auditory brainstem response in patients with obstructive sleep apnea-hypopnea syndrome].
abstract: 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.
