Insights
Older children with obstructive sleep apnea (OSA) show increased airway obstruction severity and more affected sites compared to younger children. These findings highlight age-related differences in obstruction patterns, crucial for effective pediatric OSA management.
Area of Science:
- Pediatric Otolaryngology
- Sleep Medicine
- Respiratory Physiology
Background:
- Obstructive sleep apnea (OSA) and obstructive sleep-disordered breathing (oSDB) are common in children.
- Age-related variations in the location and severity of airway obstruction during sleep are not well understood.
- Drug-induced sleep endoscopy (DISE) is a key tool for evaluating airway obstruction in pediatric OSA/oSDB.
Purpose of the Study:
- To investigate age-related differences in the sites and severity of sleep-dependent airway obstruction in surgically naive children with OSA/oSDB.
- To compare obstruction patterns across distinct pediatric age groups using DISE findings.
Main Methods:
- Retrospective chart review of 252 surgically naive children (0-18 years) with OSA/oSDB who underwent DISE.
- Children were categorized into six age groups: infants, younger toddlers, older toddlers, preschool, younger school-aged, and older school-aged.
- Obstruction was graded (none/mild, moderate, severe) at multiple airway sites, and multiple regression analyses identified age-related differences.
Main Results:
- Older children exhibited significantly higher total obstruction scores and a greater number of severely obstructed sites.
- Increased obstruction was observed in older groups at the inferior turbinates, adenoid, palatine tonsils/lateral pharyngeal wall, lingual tonsil, and tongue base.
- Younger age groups showed more obstruction in the supra-arytenoid tissue.
Conclusions:
- Significant age-dependent variations exist in the patterns and severity of airway obstruction in children with OSA/oSDB.
- These findings underscore the importance of considering age when interpreting DISE results and tailoring treatment strategies for pediatric OSA/oSDB.
Objective:
Little is known about age-related variations in sites and grade of sleep-dependent airway obstruction in children with obstructive sleep apnea (OSA) or obstructive sleep-disordered breathing (oSDB). The objective was to compare sites and grade of obstruction on drug-induced sleep endoscopy (DISE) across different age groups of surgically naïve children with OSA or oSDB.
Methods:
A retrospective chart review was performed for surgically naïve children aged 0-18 years with OSA/oSDB who underwent DISE from July 2021 to August 2023. Participants were categorized into: infants (aged 0-1 years), younger toddlers (aged 1-2 years), older toddlers (aged 2-3 years), preschool (aged 3-5 years), younger school-aged (aged 5-10 years), and older school-aged (aged 10-18 years). On DISE, obstruction was rated 0 = none/mild, 1 = moderate, 2 = severe for inferior turbinates, adenoid, velum, palatine tonsils/lateral pharyngeal wall, lingual tonsils, tongue base, epiglottis, and supra-arytenoid tissue. A series of multiple regression analyses were used to identify age differences in the grade of obstruction across all sites combined and at each individual site separately.
Results:
The sample consisted of 252 children aged 1 month to 17 years with 57.9% males. Older patients had greater total obstruction scores (B = 0.42, SE = 0.10, p < 0.01) and greater number of sites that were severely obstructed (B = 0.11, SE = 0.05, p = 0.03). Older age groups had more obstruction at inferior turbinates (p = 0.02), adenoid (p < 0.01), palatine tonsils/lateral pharyngeal wall (p < 0.01), lingual tonsil (p < 0.01), and base of tongue (p < 0.01). Younger age groups had more obstruction at the supra-arytenoid tissue (p < 0.01).
Conclusion:
Varying patterns of sleep-dependent airway obstruction should be expected across different age groups in children with OSA or oSDB.
