<p class="abstract"><strong>Background:</strong> Chronic otitis media is an inflammatory process in the middle ear cleft that poses serious health problem in developing countries. Myringoplasty is a common otological procedure to reconstruct the tympanic membrane to prevent recurrent otorrhea, and restore sound-conducting mechanism. The use of rigid endoscope in transcanal myringoplasty has significant advantage as it provides magnified, close up as well as wide angle view, less morbidity and early postoperative wound healing with better cosmetic results without compromising success rate and postoperative hearing gain. The aims and objectives of the study were to analyze the results of endoscopic transcanal interlay myringoplasty, in terms of graft uptake and hearing improvement in cases of chronic suppurative otitis media with inactive mucosal disease with central perforation.</p><p class="abstract"><strong>Methods:</strong> This is a prospective study conducted from January 2016 to August 2018 in 30 patients of inactive mucosal chronic otitis media (COM).

Background: Tympanic membrane Perforations primarily results from middle ear infections and myringoplasty is a surgical procedure used to repair the tympanic membrane and to improve hearing. The interlay technique is a newer safe and technique that has shown higher success rates and is considered better than both overlay as well as the underlay techniques. Aims and objectives: To analyze the results of interlay myringoplasty, in terms of graft uptake and hearing improvement in cases of chronic suppurative otitis media with inactive mucosal disease with large central perforation. Materials and Methods: This is a prospective study conducted from August 2015 to January 2018 in 60 patients of chronic suppurative otitis media (CSOM) with large central perforation. All patients underwent interlay myringoplasty through post aural approach after clinical examination, audiometric tests & routine investigations. Patients were called for regular follow up for 12 weeks. Results: The graft uptake rate in the present study was found to be 93.33%, Pre operatively mean air bone gap was 28.5±6.96 dB and Post operatively after 12 weeks mean air bone gap improved to 15.83±3.37. Conclusion: Interlay myringoplasty with a superiorly based TM flap is an effective technique over conventional methods in terms of both graft uptake as well as hearing improvement in large central perforation.
