Role of tympanoplasty on eustachian tube dysfunction in chronic otitis media - mucosal disease

Aim: To assess the Eustachian tube function (ETF) in chronic otitis media (COM)-mucosal disease and the role of tympanoplasty in ETF. Materials and Methods: A longitudinal study from January 2019 to June 2020 which comprised of 110 patients diagnosed with COM- mucosal disease was carried out in a tertiary care referral hospital. They were divided into mucosal active (n = 34) and mucosal inactive (n = 76) groups. Preoperative ETF was assessed with immittance audiometry by Toynbee's method. All patients underwent tympanoplasty with or without cortical mastoidectomy depending on the disease status. Postoperatively between 8 and 12 weeks after successful graft uptake, ETF was tested by William's test. Results: Out of 110 patients, 29 had Eustachian tube dysfunction preoperatively and 27 had normal ETF posttympanoplasty +/- cortical mastoidectomy. Mc Nemer test was applied and P value was found to be < 0.01 denoting a highly significant difference between the pre and postoperative ETF. Conclusion: Tympanoplasty with or without cortical mastoidectomy has a therapeutic effect on ET dysfunction in COM-mucosal disease.
