Abstract
Aims and Objective: Assessment of effect of size, site, location of perforation on the degree of hearing loss. To evaluate improvement in hearing after tympanoplasty.
Methodology: This is the retrospective and prospective study of 100 patients that underwent tympanoplasty at tertiary care hospital between January 2106 to June 2018. The follow up period was 1 year.
Results: Most common type of perforation was medium type of perforation with incidence of 44%. Hearing loss was found to be maximum with large central perforation (49.7 ± 7.07 dB). Mean improvement gain after tympanoplasty was also maximum with large central perforation (15.67 dB).
Conclusion: The larger the size of perforation, the larger is the hearing loss. The location of perforation has significant effect on the degree of hearing loss with posterior quadrant perforations causing more hearing loss. Tympanoplasty is a beneficial procedure for hearing improvement and eradication of disease and there is significant improvement after tympanoplasty.
