title: [Assessment of auditory function in patient with posterior circulation transient ischemic attack].
abstract: OBJECTIVE
  To study the hearing characteristics in patient with posterior circulation transient ischemic attack (PCTIA).
  
  
  METHODS
  Sixty-two patients diagnosed by neurologist were selected as experimental group for testing of pure tone audiometry, tympanometry, otoacoustic emissions (OAE) and auditory brainstem response (ABR). Thirty healthy subjects were chosen as control group. The data were compared between the PCTIA groups and the control group using the SPSS 14.0 software.
  
  
  RESULTS
  (1) The difference in pure tone threshold across 125 to 8000 Hz between the PCTIA group and the control group was not statistically significant (P>0.05); (2) In PCTIA patients, the prevalence of TEOAE was only 42.7%, significantly different from the control group; (3) The patients had longer ABR latency and wave interval than the normal controls (P<0.01).
  
  
  CONCLUSIONS
  Brain-stem and cochlear damage can occur in patients with PCTIA. These results suggest that OAE and ABR be used as important diagnostic test for patients with PCTIA, and might be helpful in localizing abnormality in PCTIA.
