Original Article


Sudden sensorineural hearing loss is a dire medical emergency which must be treated at the earliest to get better long term hearing results. Our study aims to determine the efficacy of intratympanic steroid (Methylprednisolone) on auditory outcomes in patients of sudden sensorineural hearing loss and study the relation between time of onset of hearing loss to start of therapy and frequency-wise recovery of hearing loss. A prospective cohort clinical study with 33 patients with sudden hearing loss of 30 dB or more were treated with the intratympanic injection of methylprednisolone and the effect of the drug was observed. In this study, 33 patients with sudden onset (unilateral or bilateral) of hearing loss were treated with intratympanic methylprednisolone. The duration at which the drug was administered and the age of the participants was taken into consideration. Main outcome measures included audiometry results at low, medium and high hearing loss frequencies. The specific frequency at which the hearing improvement took place was tabulated. It was observed that hearing improved significantly if the steroid is injected within the first 4 days of onset (p < 0.05) at all the frequencies. A gain of 15 dB or more was achieved in more than 78% patients after injecting methylprednisolone intratympanically. A statistically significant association was found between recovery rate and frequency of hearing loss with patients showing greater improvement at low hearing loss frequency in comparison to mid and high frequencies (p < 0.05). The drug efficacy does not change with the age of the patient.
