TO ASSESS THE OUTCOME OF ENDOSCOPIC INTERLAY TYMPANOPLASTY IN TERTIARY CARE CENTER

Background: Chronic otitis media is an inammatory process in middle ear cleft which is treated by a common otological procedure tympanoplasty to reconstruct the tympanic membrane and to restore sound-conducting mechanism. Rigid endoscope in transcanal interlay tympanoplasty has signicant advantage as it provides magnied, and wide angle view, with better success rate and postoperative hearing gain. The Aims and objectives were to assess the outcome of endoscopic interlay tympanoplasty, in terms of graft uptake, hearing improvement and rate of complications in cases of inactive mucosal chronic suppurative otitis media. Methods: This prospective study was conducted for 1 year at our institution in 50 patients having conductive hearing loss with dry, central perforation. All patients underwent transcanal endoscopic interlay tympanoplasty and were followed up for 3months to determine the graft uptake, hearing improvement and rate of complications. Results: Graft uptake rate in the present study was found to be 98% with residual perforation as a complication in 2% patients and no other complications were encountered. Post operatively air bone gap (ABG) after 12 weeks found to be < 20 dB ABG in 84% patients. Conclusion: Endoscopic interlay tympanoplasty is a effective method with high success rate both in terms of graft uptake as well as post operative hearing improvement and can be implemented in all cases of inactive mucosal COM.
