Abstract
In recent years several daytime symptoms resulting from pediatric obstructive sleep apnea have been recognized that affect neurobehavioral and cognitive functioning. It is important to identify patients who will benefit from treatment. Up until now the systematic analysis of obstructive sleep apnea in children has been hindered by both variable diagnostic criteria and patient care protocols. This review examines the effects of obstructive sleep apnea in children as well as treatment outcomes. Recent data suggest that some diagnostic modalities may underestimate the prevalence of sleep-disordered breathing in children. A review of the data from the past year shows a significant correlation between obstructive sleep apnea and daytime symptoms. It also shows mitigation of these symptoms with appropriate treatment. The directed history and physical examination continue to be the most effective means of diagnosis in most affected children. The polysomnogram is considered the gold standard for diagnosis but may underestimate the presence of sleep-disordered breathing in children. Some children with the diagnosis of primary snoring will benefit from treatment. In view of the profound effects of obstructive sleep apnea in children, it is vital to develop an accurate and universal system for diagnosing and treating these patients. Adenotonsillar hypertrophy is the major cause of obstructive sleep apnea in children. A directed history and physical examination followed by tonsillectomy and adenoidectomy are effective in improving the physical sequelae and quality of life of affected children.
