Obstructive Sleep Apnea Syndrome: A Child Is Not Just a Small Adult

초록

Objectives: Pediatric obstructive sleep apnea syndrome (OSAS), like adult OSAS, is characterized by intermittent upper airway collapse during sleep and is associated with anatomic and neuromuscular factors. However, the clinical manifestations, diagnostic criteria, and polysomnographic findings of OSAS in children are likely to be different from those in adults. The purpose of this study was to identify the characteristics that distinguish the clinical manifestations and polysomnographic findings of OSAS in children from those in adults. Methods: The study population consisted of 34 children (mean age, 7.6 years; range, 4 to 16 years) with OSAS and 33 adults (mean age, 40.1 years; range, 18 to 58 years) with OSAS. We compared various clinical manifestations, such as body mass index, tonsil size, severity of symptoms and signs, and polysomnographic data, between these groups. Results: Obesity was more common among the adults, whereas tonsillar hypertrophy was more common among the children. There were significant differences between the groups in the severity of symptoms and signs, including witnessed apnea, daytime sleepiness, morning headache, memory reduction, and daytime fatigue. In the children with OSAS, slow-wave sleep was relatively well preserved, and respiratory events such as apnea and hypopnea occurred mainly during rapid eye movement sleep. Conclusions: The clinical manifestations and polysomnographic findings in children with OSAS differ from those in adults with OSAS.
