[Obstructive apnea syndrome during sleep in children: diagnosis and treatment].

Marked adeno-tonsillar hypertrophy is certainly the most common respiratory disturbance found among children. Most particularly obstructive sleep apnea (OSA) leads to serious, at times fatal, consequences on the cardio-respiratory apparatus. Thus opinion in the literature unanimously holds that said syndrome is one precise indication for tonsillectomy and/or adenotomy. The present case study was performed on 19 children, age range 21 months to 6 years, with serious obstructions of the respiratory tract due to tonsillar or adeno-tonsillar hypertrophy (14 cases) or to isolated adenoid hypertrophy (5 cases). The sample was divided into 4 groups, taking into consideration the severity of the nighttime sleep obstruction and the type of obstruction. Polygraphy performed during sleep recorded objective OSA in 10 subjects with tonsillar or adeno-tonsillar hypertrophy, but no case was recorded in any subject with solely adenoid hypertrophy. The severity of the obstruction was likewise shown, judged both on the basis of frequency and duration of the pauses as well as on the cardio-respiratory complications, especially in the smallest children (less than 3 years). Furthermore, in the most serious cases significant hematological alterations were recorded. Tonsillectomy, performed in 9 of the 10 children with OSA, completely resolved the sleep disturbances and improved, or normalized, the broncho-pneumonic picture as well the hematological findings in those cases where preoperative complications were present. Even for those children who did not manifest OSA, tonsillectomy and/or adenotomy led to a more uniform rhythm and quality of their sleep.
