Abstract
We measured the pure tone audiogram and distortion product otoacoustic emissions of a patient with hearing loss after administration of streptomycin. A 33-year-old male received streptomycin for lung Tbc as an inpatient. Two months after administration of streptomycin, the patient complained of bilateral tinnitis and progressive high tone sensorineural hearing loss. We found that the DP level had declined, and the appearance of tinnitis and changes in the pure tone audiogram preceded the decline of DP level. We report a case of streptomycin-induced hearing loss and monitoring by otoacoustic emissions for early detection of drug-induced hearing loss.
