Distortion products are a subtype of otoacoustic emission. The normality of distortion products reflects correct outer hair cell function. Test results obtained from patients with neurosensorial, cochlear and retrocochlear hearing loss were analyzed, focusing on four points: correlation with audiometric results, reliability for the follow-up of dynamic cochlear disorders, frequency specificity, and topographic diagnosis.
