Abstract
Background: Sensorineural hearing loss(SNHL) is a common condition seen in an otology clinic. The causes for SNHL are chronic otitis media, Presbycusis, noise induced, ototoxic drug induced, idiopathic etc, There are various treatment modalities to treat them. Treatment outcomes are also different for all. Materials and Methods: A Prospective, observational single centre study was conducted in ENT OPD in which detailed history (onset, duration, associated symptoms of hearing loss), clinical examination followed by Pure tone audiometry was done. Hearing loss was calculated using Extended Fletcher’s Index. 35 patients received treatment depending on their diagnosis and followed up for three months with pure tone audiometry and then results were condition seen in an otology clinic. The causes for SNHL are chronic otitis media, Presbycusis, noise induced, ototoxic drug induced, idiopathic etc, There are various treatment modalities to treat them. Treatment outcomes are also  compared after one month and three months of treatment.  Results: Pre and post-treatment pure tone audiometry values were analyzed. Statistically significant differences in improvement was observed between younger and older age group, and also significant changes in outcome among the causes. Conclusion: ISSNHL is the most common cause of SNHL in the younger age group with a better result, and Presbycusis is the most common cause of SNHL in the older age group with worse outcome.
