Reversible cardio-pulmonary changes due to adeno-tonsilar hypertrophy.

Adeno-tonsillar hypertrophy, with signs of upper airway obstruction is a common presentation in ENT clinics. Recently it is identified as a major cause of sleep apnea syndrome. Several isolated case reports of pulmonary hypertension and corpulmonale appeared in the literature. The authors report two such children aged less than 2 years with cardio-pulmonary changes occurring secondary to chronic adeno-tonsillar hypertrophy that were successfully treated with the surgical removal.
