PTA in our patient recorded one, three, and 14 days after onset of Sudden Sensorineural Hearing Loss in the right ear (first episode). (a) Pure Tone Audiometry recorded one day after hearing loss onset showing a moderate sensorineural hearing loss in the right ear with an average auditory threshold of 49.54 dB HL and normal hearing threshold in the left side. (b) Pure Tone Audiometry recorded three days after hearing loss onset; hearing in the right side significantly improved (average threshold: 23.2 dB HL). (c) When recording Pure Tone Audiometry 14 days after sudden hearing loss onset, and 4 days after cessation of high-dose corticosteroid therapy, hearing in the right ear returned to previous levels with an average threshold of 54.09 dB HL.
