Effect of adeno-tonsillectomy on hearing threshold and middle ear pressure.
Out of 50 children (100 ears) undergoing adeno-tonsillectomy, 34 ears had hearing threshold 20-50 dB (20 dB is normal) and 32 ears showed negative middle ear pressure of 100 to 400 mmH2O (100 mmH2O is normal). Post-operatively only 7 ears had hearing threshold of 20-30 dB and negative middle ear pressure of 100 to 200 mmH2O. Thus adenoidectomy improves eustachian tube functions.
