In this paper, we studied 3 children with moderate hypertrophy of the
palatine tonsils and adenoids and serious congenital diseases. The fir
st patient was a 4-year-old girl with Fallot's tetralogy, the second w
as a 6-year-old girl with Goldenhar syndrome and ventricular septal de
fect, aortic stenosis and patent ductus arteriosus, and the third was
a 3-year-old boy with cerebral palsy and epilepsy. We examined obstruc
tive apnea during sleep in these patients using all-night polysomnogra
m or apnomonitor before surgical therapy. After tonsillectomy or adeno
-tonsillectomy we confirmed significant improvement of clinical sympto
ms and obstructive sleep apnea in these patients by all-night polysomn
ograms or apnomonitor.
