ABSTRACT Objective: To determine Eustachian tube function in tubotympanic type of chronic ear disease and to correlate Eustachian tube function with pathological change in middle ear mucosa. Materials and Methods: A prospective study of the cases of tubotympanic type of chronic suppurative otitis media was undertaken. Patients were subjected to clinical examination followed by audiometry tests and impedence audiometry to determine eustachian tube functions. Patients were then subjected to myringoplasty and eustachian tube function were then reassessed post operatively. Results: In our study, out of 30 cases who underwent myringoplasty, 21 cases had successful surgical outcome and 9 cases were failed. Out of 24 cases of good Eustachian tube function, 21 cases had successful surgical outcome intends of taking up graft, absence of otorrhea and improvement in hearing. In remaining 3 cases, there was recurrence of otorrhea with central perforation. All the 6 cases with poor Eustachian tube function had surgical failure. Conclusion: The prognosis of the middle ear reconstructive surgery has direct correlation with Eustachian tube functions and Eustachian tube function tests should be a routine investigation in all the cases planned for surgical reconstruction of the middle ear.
