Thenmozhi K, Faiza Sameen K

Abstract :

Aim: Among the many sufferers of tinnitus, a few have normal he� sensitivity. The aim of the study is to find the relevance of high frequency audiometry in tinnitus patients with normal he� in conventional pure tone audiometry.

Subjects and Methods: A small group of 10 tinnitus patients were selected with normal pure tone audiogram and high frequency audiometry was performed and the results were analyzed.

Results: The tinnitus patients showed higher thresholds in high frequency audiometry when compared to conventional pure tone audiometry. There was a correlation between tinnitus laterality and high frequency he� loss.

Conclusion: High frequency audiometry provides essential information in tinnitus patients having normal pure tone thresholds. The association between tinnitus laterality and asymmetry of the high frequency audiometry suggests a potential causal role for the high frequency he� loss in tinnitus etiopathogenesis.
