Exploring the Association Between Clinical Characteristics and Etiopathogenesis of Tinnitus: A Cross-Sectional Study

Background  Tinnitus is the perception of internal noises like ringing or hissing, which can greatly affect quality of life. It involves increased neuronal synchrony and interactions with non-auditory brain structures. There's no universal classification system due to its varied origins and mechanisms, and current protocols often overlook physiotherapy, especially for non-otologic causes such as Cervicogenic and Temporomandibular disorders. This study seeks to link clinical features with tinnitus characteristics to better identify underlying causes and improve diagnostic protocols. Methods A prospective observational cross-sectional study was conducted from June 2022 to March 2024 in a rural hospital in Central India, involving 75 patients with tinnitus. The study included comprehensive history, clinical examination, and physiotherapy assessments to categorize tinnitus into otologic, non-otologic, or central types. Each type was analyzed to correlate its characteristics with underlying causes. The findings aim to improve diagnostic protocols and deepen understanding of tinnitus origins. Results The otologic origin of tinnitus was found in 53 (70.7%) patients. Out of 16 (21.3%) patients in the non-otologic category, three (4%) of patients had a somatosensory origin, seven (9.3%) of patients were found to have a somatosensory cervicogenic origin of tinnitus, and six (8%) of patients had a central origin of tinnitus. The remaining six (8%) were found to have mixed origins. Conclusion Otologic tinnitus was the commonest cause of tinnitus, followed by cervicogenic tinnitus. Ours is probably the first study that classifies tinnitus based on otologic and non-otologic origin, with special emphasis on cervicogenic origin tinnitus. Further research could study tinnitus chronicity, causes, and treatments using objective measures and advanced diagnostics.
