ABSTRACT |
The function of the eustachian tube was evaluated with impedance audiometry before and after tonsillectomy and adenoidectomy. In all cases the first tympanometry was performed on the day before operation and everyday after operation. The pressures were classified in tympanogram type A (+50 to
-99mmH2O), type C1 (-100 to -199 mmH2O) and type
C2 (less than -200mmH2O). Before operation, 36 ears had type A and 4 ears had type
C2. The operation produced changes in middle ear ventilation. In 75% of ears, there was noted to a negative pressure of
-100mmH2O or less on the first day after operation. Normalization of the pressure was noted earlier relatively and occurred in all cases on the 9th day after operation.
