Effectiveness of lignocaine-dexamethasone periauricular injection on treating tinnitus

Abstract

Tinnitus is a highly prevalent disorder with no effective treatment. The various topical treatment used are ineffective and the benefits are mainly due to its placebo effect. A study on a series of twelve patients was carried out in a tertiary hospital in Bhutan to see the effectiveness of lignocaine-dexamethasone periauricular injection on treating tinnitus. To remove the bias in recording tinnitus by subjective response, we used a single patient as both case and control for the first time in such studies. The study found that there was no significant difference in reduction in tinnitus severity in both case and control ears even after eliminating the subjective response bias.
