Abstract
A study was carried out on caloric response and pure tone audiometry in 308 patients with internal ear disorders. 1. Patients with unilateral sensorineural hearing loss or bilateral asymmetrical sensorineural hearing loss had unilateral canal paresis more frequently than did patients with normal hearing or bilateral symmetrical hearing loss (p<0.01). 2. Those patients who had unilateral sensorineural hearing loss and unilateral canal paresis tended to experience only one episode of vertigo in comparison with those who had normal hearing and normal caloric responses, or bilateral symmetrical hearing loss and normal caloric responses (p<0.05).
