A new scoring system for upper airway pediatric sleep endoscopy

Area of Science:

• Otolaryngology
• Pediatric Sleep Medicine
• Respiratory Medicine

Background:

• Sleep-associated upper-airway obstruction is a significant cause of morbidity in children.
• Standardized, quantitative assessment of airway anatomy is crucial for surgical planning and research in pediatric sleep disorders.

Purpose of the Study:

• To design, implement, and evaluate a scoring system for quantifying airway obstruction during pediatric drug-induced sleep endoscopy (DISE).

Main Methods:

• A retrospective case series of children with sleep-related breathing disorder undergoing polysomnography and DISE.
• Flexible fiber-optic laryngoscopy was performed, with videos assessed by 4 raters using a 4-point scale for obstruction at 5 airway locations.
• Internal reliability (interrater and intrarater ICCs) and external validity (correlation with polysomnography indices) were evaluated.

Main Results:

• The scoring system demonstrated substantial agreement among raters (70% of ICCs > 0.6).
• Higher total obstruction scores correlated with lower oxygen saturation nadir (P = .04).
• Multilevel airway obstruction identified by the system was associated with significantly worse polysomnography indices (P = .02).

Conclusions:

• The proposed scoring system is easy to use, achieves good internal reliability and external validity for quantifying obstruction in pediatric DISE.
• Standardized reporting of DISE outcomes will improve clinical communication and interpretation of findings.
• This system aids in informing site-directed surgical interventions for obstructive sleep apnea in children.
