title: [Ocular vestibular evoked myogenic potentials in response to bone-conducted sound stimuli: results of measurements in healthy adults].
abstract: OBJECTIVE
  This study aims to determine the normal values of ocular vestibular evoked myogenic potentials (oVEMP) in response to bone-conducted sound stimuli in healthy adults.
  
  
  METHODS
  The study included 42 healthy adult volunteers (18 males, 24 females; mean age 39.7±11.2 years; range 20 to 60 years) (84 ears) with pure tone mean thresholds better than 20 dB, no detected nystagmus during positional tests, and no complaint involving the ear. The participants were performed otorhinolaryngologic examination, audiologic evaluation, and positional tests. Ocular vestibular evoked myogenic potentials were measured using air-conducted and bone-conducted sound stimuli and results were compared.
  
  
  RESULTS
  No statistically significant difference was detected between the side of the ear tested and sex in terms of the latency and amplitude values (p>0.05). There was no correlation between n1, p1 latency and amplitude values with age and (p>0.05). Mean n1 latency was 9.9±1.87 milliseconds and p1 latency was 12.75±1.41 milliseconds. Mean amplitude was 5.06±1.97 µV. Interaural asymmetry ratios were 4±3% for p1, 4±3% for n1, and 8±6% for amplitude.
  
  
  CONCLUSIONS
  Data obtained in this study may be accepted as normal values for healthy adults and used as reference in oVEMP studies with bone-conducted sound stimuli.
