Abstrakt: To assess the eustachian tube function by impedance audiometry (Toynbee's test) in patients of mucosal type of chronic otitis media (inactive stage) and to assess the correlation of eustachian tube function with the results—i.e., success or failure of tympanoplasty in these patients in terms of graft uptake. This was a prospective observational study carried out over one and half years in Department of E.N.T. & Head and Neck Surgery, a tertiary care hospital. The study group comprised of eighty-seven patients who were diagnosed with chronic otitis media mucosal type- inactive stage and were planned for tympanoplasty or tympanoplasty with cortical mastoidectomy. Written informed consent was taken from all patients. The eustachian tube function was assessed preoperatively by impedance audiometry (Toynbee's test). The surgical outcome was tested by looking at the status of the tympanic membrane postoperatively. The surgical outcome in terms of whether a defect was present in the tympanic membrane was compared with the preoperative eustachian tube function. 98.6% of patients with successful surgical outcome had normal eustachian tube function preoperatively while the neo-tympanic membrane was intact in 63.63% and 33.33% of patients with pre-operative partially impaired and grossly impaired eustachian tube function respectively. From our study, we concluded there was a strong association between functioning eustachian tube and graft uptake in tympanoplasty. So eustachian tube plays important role in successful outcome of surgery. [ABSTRACT FROM AUTHOR]
