title: Evaluation of hearing and cochlear function by audiometric testing in patients with hyperemesis gravidarum.
abstract: BACKGROUND
  The aim of this study was to investigate cochlear functions in patients with hyperemesis gravidarum (HG).
  
  
  METHODS
  Twenty-nine HG patients (58 ears) and 31 healthy control subjects (62 ears) were included. Audiometry testings at 250 and 500 Hz and 1, 2, 4, 8, 10, 12, 14, 16 kHz were performed to the patients and controls.
  
  
  RESULTS
  Mean age of patients with HG was 26,5 ± 4,4 years and the mean age of control group was 28,0 ± 4,2 years. At the time of the tests mean gestational age of the HG group and controls were 9 and 11 weeks respectively. No differences were observed between the groups in tympanic membrane status, or other otolaringological evaluations. No significant differences were observed in audiometric tests at any frequencies between the groups (p values for all > 0.05).
  
  
  CONCLUSIONS
  There was not a difference between pregnant cases with HG and cases with normal pregnancy in terms of audimetric tests. Cochlear functions are not affected remarkably in women with HG.
