Assessment of Hearing Outcome after Type-I Tympanoplasty – A Prospective Study

Background: Chronic suppurative otitis media is a longstanding infection of the middle ear cleft characterized by persistent or recurrent aural discharge, deafness and perforation of tympanic membrane. Type I tympanoplasty is a surgical procedure that repairs tympanic membrane perforation. Methods: There were a total of 62 patients of age group 15-45 years of chronic otitis media, mucosal type who underwent type I tympanoplasty in ENT Dept, DMCH, Laheriasarai, Darbhanga, during Feb 2025 to Aug 2025. Pure tone audiometry of the patients was done before the surgery and one month and three months following surgery and the hearing improvement was assessed in each case. Results: In this study, graft uptake was highest (95%) in posterior perforations, 75% in anterior perforations and lowest (63.64%) in combined perforations. The mean hearing improvement one month following surgery was 7.16 dB and three months following surgery, it was 7.78 dB. Conclusions: Chronic otitis media is a treatable cause of hearing loss. Type-I tympanoplasty is a safe and effective method to remove the disease of the middle ear and reconstruct the tympanic membrane perforation.
