Abstract

Sleep-disordered breathing in children can include habitual snoring, obstructive hypoventilation, upper airway resistance syndrome, and obstructive sleep apnea. Obstructive hypoventilation in children is characterized by COâ‚‚ retention caused by prolonged partial upper airway obstruction during sleep. To date, there have been few studies regarding the clinical significance and management strategies in pediatric obstructive hypoventilation, although it is a unique feature of pediatric sleep-disordered breathing. In this report, we describe two cases of obstructive hypoventilation that demonstrated improvement following upper airway surgery. These results suggest that upper airway surgery could be an additional treatment modality in obstructive hypoventilation.

  Fig. 2 Clinical and radiologic findings of case II patient. Endoscopic findings and lateral cephalometry view showed bilateral tonsillar hypertrophy, floppy soft palate and adenoid vegetation. (A) Endoscopic findings of oropharynx. Bilateral palatine tonsillar hypertrophy and floppy soft palate were noted. (B) Endoscopic findings of nasopahrynx. (C) Lateral cephalometry view. Adenoid vegetation was observed.
