[Effects of adentonsillectomy on pulmonary function parameters]

Adenotonsillar hypertrophy is a common finding among children which in untreated cases may result in serious cardiopulmonary problems. There are limited studies about the effect of adenotonsillectomy on pulmonary function parameters. Does adenotonsillectomy affect on pulmonary function? This study is performed to reveal this purpose. In a pre- and post-treatment clinical trial on 39 children between 6-13 years old with indication of adenotonsillectomy due to obstructive respiratory symptoms [because of prominent hypertrophy of tonsils and/or adenoid tissue], 5 main Spirometric parameters weere measured before and 2 months after adenotonsillectomy with a standard method and data were analyzed by paired t-test. 39 children [56% male and 44% female] with a mean age of 8.95 +/- 1.93 were evaluated. 4 main Spirometric parameters increased: FEV1/FVC from 89.H12.7 to 97 +/- 4.6, FEV0.5/FVC from 70.9 +/- 15.5 to 81.U11.8, FEV25-75 from 1.9 +/- 0.6 to 2.2 +/- 0.7, MEF50 from 2 +/- 0.6 to 2.4 +/- 0.7 and all the improvement was statistically significant [P<0.0001]. There was no statistically significant change in FEV1/ PEFR index. Due to obvious changes of 4 main Spirometric parameters, it can be deduced that adenotonsillectomy is of effective roles in improvement of pulmonary function
