Lyons M, et al. - In children presenting with early vs late onset sleep disordered breathing (SDB), researchers conducted this retrospective, cross-sectional study to compare the frequency and type of diagnoses correlated with pharyngeal dysfunction (PD). From a prospectively kept surgical database, a consecutive series of children ≤ 3 years old who had management for SDB were retrospectively identified. They compared the early onset group with two separate late onset (≥ 4years old) groups. Early onset patients with SDB were more likely to have gastroesophageal reflux disease or swallowing dysfunction while patients with later onset more commonly presented with related asthma or obesity. No statistically significant difference was found in airway lesions between groups. The authors concluded that early-onset SDB is associated more frequently with conditions that cause PD than later-onset SDB. Identifying these conditions and optimizing their management can have an impact on pediatric SDB treatment outcomes.
