Obstructive sleep apnea syndrome in children.

Area of Science:

• Sleep Medicine
• Pediatric Otolaryngology
• Orthodontics

Background:

• Repetitive partial or complete upper airway obstructions during sleep cause chronic snoring and related symptoms.
• The significance of upper airway resistance increases during sleep may outweigh the number of obstructive sleep apneas.
• Clinical symptoms can manifest even when nocturnal oxygen saturation is not severely affected by partial airway occlusion.

Purpose of the Study:

• To highlight the importance of upper airway resistance and craniofacial morphology in sleep-related breathing disorders.
• To discuss diagnostic tools and treatment options for pediatric sleep-disordered breathing.
• To evaluate the impact of airway occlusion on facial development.

Main Methods:

• Polygraphic evaluation using esophageal pressure measurements and breathing frequency during sleep.
• Assessment of craniofacial morphology and its interaction with airway adequacy.
• Clinical observation of treatment outcomes for tonsillectomy, adenoidectomy, and nasal continuous positive airway pressure.

Main Results:

• Esophageal pressure and breathing frequency are key diagnostic features in prepubertal children.
• Tonsillectomy and adenoidectomy can benefit children with small upper airways during sleep.
• Nasal continuous positive airway pressure effectively treats airway occlusion but does not correct mandibular deficiency.

Conclusions:

• The interplay between upper airway patency and craniofacial structure is critical for managing sleep-disordered breathing.
• Orthodontic interventions may obviate the need for maxillomandibular surgery in pubertal patients.
• Comprehensive evaluation is necessary to address both airway obstruction and associated skeletal discrepancies.
