There are limited studies about the effect of adentonsillectomy on pulmonary function parameters. Does adenotonsillectomy affect on pulmonary function? This study is performed to reveal this purpose.
Materials and Methods: In a pre- and post-treatment clinical trial on 39 children between 6-13 years old with indication of adentonsillectomy due to obstructive respiratory symptoms (because of prominent hypertrophy of tonsils and/or adenoid tissue), 5 main Spirometric parameters were measured before and 2 months after adenotonsillectomy with a standard method and data were analyzed by paired t-test.
Results: 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 89.1±12.7 to 97±4.6, FEV0.5/FVC from 70.9±15.5 to 81.1±11.8, 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.
Conclusion: Due to obvious changes of 4 main Spirometric parameters, it can be deduced that adenotonsillectomy is of effective roles in improvement of pulmonary function.
