Aim : Pathophysiology of Eustachian tube significantly affects the result of middle ear reconstructive surgery. The aim of this study is to ascertain the relevance of preoperative assessment of tubal function on the results of myringoplasty and to correlate the outcome of surgery with the tubal function gradings. Materials and Methods : A total of 58 cases of dry central perforation of tympanic membrane were divided into two groups. In control group A, pre-operative Eustachian tube function was not checked. In Test group B, pre-operative Eustachian tube function was checked by modified inflation-deflation test using impedance audiometer. Results : Success was assessed at 4th month postoperatively on the basis of intact drum. The results between both groups were compared using Chi-square test. There was no statistically significant difference (P< 0.05) between the control and the test group. Conclusion : The capability to reduce an applied negative pressure correlates well with the successful result of a tympanic membrane graft. However, failure to equilibrate negative pressure does not discriminate between success and failure of this operative procedure.
