Abstract
A study of 111 patients of presbyacusis revealed an earlier onset of hearing impairment in our country, as compared to the occident, probably due to poor nutrition. There was a higher incidence of “presbyacusis praecox” in women than in men. The hearing loss increased progressively decade by decade with the higher frequencies showing more loss than the lower. However, even these lower frequencies showed hearing impairment of more than 30 dB in all decades. Types IV and V audiometric curves (Schuknecht, 1974) predominated in both sexes, showing thereby that the lesion in these cases of presbyacusis was mainly an atrophy of the spiral ligament or an “inner ear conductive deafness”. Retrocochlear lesions were present in only four cases.
