Figure 4

Pure Tone Audiometry recorded one, 14, and 60 days after onset of sudden hearing loss in the left ear (second episode). (a) Pure Tone Audiometry confirmed hearing loss in the left ear, with an average threshold of 38.18 dB HL; threshold in the right ear was unmodified compared to the exam performed 14 days after cessation of previous treatment (56.09 dB HL); (b) Pure Tone Audiometry recorded 14 days after hearing loss onset showed a significant improvement of hearing loss in the left ear (average: 22.72 dB HL) but also in the right ear (average: 30.45 dB HL); (c) Audiometry 60 days after left sudden hearing loss onset showed no significant differences compared to previous exam, with preserved hearing threshold in both ears.
