It is well known that hypertrophic tonsils and adenoids may cause upper-airway obstruction. The aim of this study is to determine the mean pulmonary arterial pressure (mPAP) in children with hypertrophic tonsils and adenoids and to clarify whether tonsillectomy and adenoidectomy (T&A) has any effect on mean pulmonary arterial pressure of these children. ⋯ This study showed that obstructive adenoid and tonsillar hypertrophy causes higher mPAP values in children and revealed that T&A is an effective therapeutic measure in such patients.
