Ocular vestibular evoked myogenic potentials in response to air conducted stimuli: clinical application in healthy adults.

OBJECTIVES This study aims to determine the normal values for ocular vestibular evoked myogenic potentials in response to air conducted stimuli in healthy adults. PATIENTS AND METHODS Thirty-six healthy adult participants with no ear complaints were enrolled. Ocular vestibular evoked myogenic potential tests were performed to all participants. Latency and amplitude values of the waves were recorded. RESULTS The mean N1 latency was 9.62±2.02 (4.30-16.00) msec and the mean P1 latency was 14.90±2.33 (9.0-21.00) msec. The mean amplitude was 3.36±1.36 (1.06-8.48) µV. There was a positive correlation between N1 and P1 latencies and age (r=242, p=0.0359 for N1; r=250, p=0.030 for P1). CONCLUSION Ocular vestibular evoked myogenic potentials can be obtained easily and can be used in the evaluation of vestibular disorders. However, the effect of age should be considered when interpreting results.
