Abstract
To add to the limited body of literature on ocular vestibular evoked myogenic potential (oVEMP) responses in children and to assess a different montage for oVEMP recording. To evaluate the characteristics of the oVEMP response in children and compare the results with that of a group of healthy adults. Prospective descriptive study from a tertiary referral center. Twenty-two children (mean age = 6.3 yr, standard deviation = ±1.5, range = 3.5-8.9 yr) were recruited from families whose parent(s) were employed by the Cincinnati Children's Hospital Medical Center (CCHMC). Pediatric participants were categorized by age into three groups for data analysis. The comparison adult group of ten participants were members of the employee staff at CCHMC. Audiometric assessment was completed in all participants. The latency, amplitude, and threshold of the oVEMP responses were recorded using a modified electrode montage with reference at the chin and compared between the pediatric and adult participants. All participants completed testing and had bilateral measurable oVEMP responses using a 105-dB nHL, 500-Hz tone burst stimulus. Comparison between right and left ears across all participants for each oVEMP characteristic found no statistically significant difference. oVEMP testing showed no significant differences with respect to latency, amplitude, interaural amplitude asymmetry, and threshold of response as a function of age. oVEMP responses for ages ≥3 did not differ from responses in adults.
