Abstract
Introduction- Hearing loss is one of the most common sensory deficits in humans which has negative influence on multiple aspects of individual’s life. Tympanic membrane perforation because of chronic otitis media or trauma results to conductive hearing loss. Prompt management of chronic otitis media reduces complications related to tympanic membrane perforation, thereby enhancing the quality of life for patients.
Aim and objective-
To study the correlation between site of perforation with degree of hearing loss.
Method and Methodology- This prospective observational study was conducted from December 2020 to December 2022 on 60 patients in the Department of Otorhinolaryngology and Head & Neck Surgery at Medical college and hospital, India. All the patients in the age group of 18-50 years from both sexes having tympanic membrane perforation in the inactive stage were included in the study. Photo documentation of the tympanic membrane perforation of the patients was done using oto-endoscope. Based on the site, tympanic membrane perforation was divided into 3 categories- Anterior, Posterior and Combined.
Result- Majority of the patients (50%) were in the age group of 18-40 years having female preponderance. Most of the patients presented with ear discharge (83.3%). Majority of perforations were combined perforations (63%). We also noted that the highest mean conductive hearing loss was seen in the combined perforations at 25.88 (+/- 11.05) dB.
Conclusion- Degree of hearing impairment is affected by the site of perforation.
