[Profound bilateral sensorineural hearing loss: a result of viral infections]

A patient is presented with profound bilateral sensorineural hearing loss, as a result of viral infections. The extensive clinical diagnosis was carried out. The findings of multiple audiological and immunological tests helped to fix the proper treatment and the period of its application. In consequence, the hearing in the right ear showed a significant improvement, but the left ear wasn't recovering. The inflammatory process occurred much earlier in the left ear and caused the indivertible hearing loss.
