Abstract
Sudden sensorineural hearing loss can be a frightening experience for the sufferer and needs immediate treatment. Systemic steroid therapy has been the mainstay of treatment of this condition but concerns about their side effects has led to their use by intratympanic injection. We studied the results of intratympanic dexamethasone (IT-Dexa) both as a primary therapy and as salvage treatment after failure of oral steroids. A total of 39 patients of SSNHL were studied prospectively. Of these 23 were given oral steroids. Ten of these showed no response and were treated with IT-Dexa 4mg/ml twice a week for two weeks. In addition, 16 patients who reported later than two weeks or had concomitant medical disorders like diabetes and/or hypertension were treated with IT-Dexa. While oral steroids showed hearing improvement (≥ 10dB) in 56.5% patients, the recovery rate was 62.5% and 80% in those treated primarily with IT-Dexa and as salvage therapy respectively. There was a negative correlation of delay in institution of treatment with hearing recovery. Conclusion: intratympanic dexamethasone is a safe and effective treatment and should be offered to patients as a primary treatment modality and also as salvage therapy after failure of oral steroids. For best results the treatment should be started at the earliest.
