Obstructive sleep apnea syndrome (OSAS) is characterized by prolonged, gene
rally partial, upper airway obstruction associated with hypoxemia and/or hy
percapnia. Main etiological factors include hypertrophy of the tonsils and
adenoids, craniofacial abnormalities with reduction in the upper airway cal
iber, abnormality of neural upper airway control, or a combination of these
factors. Symptoms depend an age, but they always include snoring and breat
hing difficulties during sleep. Diagnosis of OSAS must be established early
in order to prevent complications It is suspected on history, physical exa
mination and investigative confrontation such as nasofibroscopy and imaging
. Polysomnography is the gold standard for diagnosis, scoring of the obstru
ction and distinction between primary snoring and obstructive breathing. Ad
enotonsillectomy is an effective therapy For selected patients, craniofacia
l surgery may be helpful. Same children require continuous positive airway
pressure or the nasopharyngeal tube. Tracheotomy is rarely indicated (C) 20
