Ménière's disease (right ear). In this patient with Ménière’s, cVEMP reflexes are reduced in the affected ear while the oVEMP reflexes are preserved bilaterally. vHITs and subjective visual horizontal tests are normal. The audiogram shows a significant asymmetry with the affected ear showing a flat moderately-severe sensorineural hearing loss. Caloric testing also shows a significant asymmetry, where the right ear shows negligible vestibular response to ice-water irrigation.
