Background: Mucosal type of chronic otitis media is characterized by a central perforation of the tympanic membrane with or without ossicular chain involvement. The perforation is in the pars tensa and is mostly sequelae to an earlier attack of acute otitis media. The tympanic membrane perforation may be caused by chronic suppurative otitis media (CSOM) or the following trauma, mostly resulting in hearing loss. Aim: To compare the hearing outcome in patients undergoing type one tympanoplasty using temporalis fascia versus patients undergoing type one tympanoplasty using fascia lata graft. Method: Patients with mucosal chronic suppurative otitis media were chosen from the OPD or outpatient department of otorhinolaryngology at Dr DY Patil Hospital; between May 2019 and April 2021. This prospective study includes 50 patients, of which 25 patients were operated on for myringoplasty with temporalis fascia, and the other 25 were operated on for myringoplasty with fascia lata graft. The pre-operative and post-operative hearing assessment was done by audiometry (AB gap), and improvement in PTA findings was compared. Results: There is a significant improvement in the AB gap in patients undergoing type one tympanoplasty with tensor fascia lata compared to those who underwent the same surgery but with temporalis fascia. Conclusion: As observed by our study, significant improvement in AB gap in patients undergoing type 1 tympanoplasty with tensor fascia lata was present compared to those who underwent the same surgery but with temporalis fascia. Thus, performing type one tympanoplasty with tensor fascia lata can be suggested for better improvement in the AB gap.
