HL (the conductive component was minimal and ranged from 10 to 15 dB). Hearing was normal in the left ear (Fig. 1a). The patient reported improvement of her hearing symptoms 2 days after starting prednisone, and an audiogram obtained 2 weeks after initiation of prednisone demonstrated a pure tone average improvement of 20 dB HL in her right ear, which brought her to a normal level that was symmetric with her left ear (Fig. 1b).
