Audiovestibular involvement in leprosy.

100 leprosy patients were studied for audiovestibular involvement. Conductive hearing loss was detected in 6 cases of BT leprosy, all of them having coincidental chronic middle ear infection. Sensori-neural hearing loss was detected in 10 cases, of which 6 had LL, 2 BT and 2 pure neuritic type of disease respectively. All the cases of lepromatous leprosy having sensorineural hearing loss had evidence of ENL reaction. Vestibular involvement was not detected in any of the cases. Evaluation of audiovestibular function was also carried out in 50 fresh cases of leprosy and after 3 months, 6 months and 1 year of multidrug therapy to ascertain any ototoxic side effects of antileprosy drugs. No audiovestibular dysfunction was detected in these patients at any time during follow-up.
