Objectives/Hypothesis To evaluate in patients with idiopathic sensorineural hearing loss whether pulse therapy with methylprednisolone leads to better recovery of hearing than traditional oral prednisolone therapy. Study Design Randomized controlled trial. Methods Sixty-seven patients diagnosed with idiopathic sensorineural hearing loss were randomly divided into two groups based on therapy. The study group received 500-mg daily intravenous methylprednisolone for 3 consecutive days, followed by 1 mg/kg (maximum 60 mg) oral prednisolone for 11 days (total treatment: 14 days). The control group received 1 mg/kg (maximum 60 mg) oral prednisolone for 14 days. Hearing change was evaluated by comparing initial hearing tests and the third-month hearing tests in three ways: 1) pure tone improvement in each individual tone (0.5, 1, 2, 3, and 4 kHz); 2) word-recognition score improvement; and 3) complete, partial, and no recovery of hearing calculated (as defined by American Academy of Otolaryngology - Head and Neck Surgery Clinical Practice Guidelines). Results Sixty of 67 patients, 29 of 34 patients in the study group and 31 of 33 patients in the control group, completed the study. Frequency-specific hearing improvement did not differ significantly among the groups. Word-recognition score improvement was 20.34% ± 27.35% for the study group and 13.41% ± 23.48% for the control group, which had no statistically significant difference. There was also no significant difference in hearing recovery rates for the two groups. Conclusion Pulse therapy with methylprednisolone and traditional oral prednisolone therapy resulted in similar hearing improvement.
