To evaluate the effect of adenoidectomy on Eustachian tube function, opening pressure was measured before and immediately after adenoidectomy and every month for 5 months in 10 children, and the inflation-deflation test was performed every month for 6 months after the insertion of tympanostomy tubes in 42 children.The following results were obtained: 1) opening pressure decreased immedeately after adenoidectomy in about half of the children, 2) inflation-deflation test results did not improve after adenoidectomy, at least for 6 months, 3) children with adenoid hypertrophy failed to respond to the inflation-deflation test at all, while 20% of the children treated with adenoidectomy showed a positive response to the test. One can conclude that children with adenoid hypertrophy should be treated with adenoidectomy.
