Eighth nerve evaluation in leprosy.
25 cases of bacillary positive leprosy patients and 25 age and sex matched controls were investigated for assessment of cochleo-vestibular status. Impaired hearing was complained of by 4 patients. None had tinnitus, dizziness or vertigo. On testing 44% patients were found to have unilateral or bilateral perceptive deafness. Specialised tests of hearing indicated that the deafness was of cochlear type. The vestibular functions were not affected. Leprosy seems to selectively involve the cochlea.
