Abstract
Aim: to determine the effect unilateral nasal obstruction on the middle ear pressure, Eustachian tube function and the type of Tympanometry of both ears before and after operation. Patients and Methods: Total 70 patients with unilateral nasal were recruited for this study .Tympanometry, Eustachian tube function and middle ear pressure were compared for all patients before and after operation. Result: 39 patients had type A tympanogram,8 type B and 24 type C before operation for the same side of ACP while for the other side there were (50 type A, 2 type B and 15 type C) tympanogram patients but after FESS operation there were (55 type A,1type B and 14 type C) tympanogram patients for the same side and (68 type A, 0 type B and 2 type C) tympanogram for the other side. also middle mean ear pressure for the same side before surgery was (-125± -9.3) and (-92.42± -7.4) for the other side and became (-45.14± -6.39) for the same side and (38.3±6.1) for other side, while ETF tests were bad for all ears on the same side of lesion and for (45) ears on the other side before surgical correction of nasal obstruction which became good ETF tests for all (70) patients on both sides. Furthermore, there were no significant correlations between type of tympanogram, middle ear pressure or ETF tests with the age and sex of patients. Conclusion: there was a definite relationship between nasal obstruction and type of tympanogrsm, MEP and ETF. Good Eustachian tube function tests aren’t always associated with type A tympanogram.
