Laryngeal pathologies as an etiologic factor of obstructive sleep apnea syndrome in children.

Obstructive sleep apnea syndrome is a chronic condition of airway obstruction, common in children, with known clinical consequences. The etiology of OSAS in children stems from a combination of obstructing structural factors and neuromotor factors. In children, tonsilar hypertrophy accounts for this condition in most cases, however, in about 20% of the cases, other causes are involved.
