Correlation of Eustachian Tube Dysfunction with Results of Tympanoplasty in Mucosal Type of Chronic Suppurative Otitis Media.

To Assess the relation between eustachian tube function and outcome of tympanoplasty in mucosal type of chronic suppurative otitis media, a prospective study was carried out over a period of one and half years (January 2016-July 2017) at a tertiary referral centre (Gujarat Cancer Society Medical College and Research Institute, Ahmedabad). Total 90 Patients of any age and sex and with Mucosal type of chronic suppurative otitis media and Patients with follow up of 12 months were selected. The Eustachian Tube function was assessed preoperatively by pressure swallow equalization test and impedance audiometry. All patients were categorized based on function of eustachian tube. All patients were operated by type 1 tympanoplasty with or without mastoidectomy. We measure the Graft uptake rate after type 1 tympanoplasty (with or without mastoidectomy) in patients with or without eustachian tube dysfunction. Graft uptake rate is higher in patients with normal or mild eustachian dysfunction compared to severe eustachian tube dysfunction. In our study we found 87% success rate in patients with normal Eustachian tube function, 80% in partially impaired Eustachian tube function, and 70% in totally impaired Eustachian tube. So, pre-operative planning in tympanoplasty surgery eustachian tube function assessment is must to increase graft uptake rate by preoperative utilization of decongestant. It is also important to comment outcome of surgery.
