INTRODUCTION: Obstructive sleep apnea (OSA) in young children is caused by upper airway obstruction and is associated with changes in cognitive development, temperament and behavior. Adenotonsillectomy (AT) is often utilized as first line therapy for pediatric OSA. Children with laryngomalacia (LM) have a high chance of residual OSA after AT. There is paucity of literature regarding surgically naïve young children with OSA and laryngomalacia. Our study aimed to compare demographics, comorbidities and outcomes associated with OSA in surgically naïve young children with and without laryngomalacia.
METHODS: Retrospective chart review of surgically naïve young children (<2-year-old) with polysomnogram (PSG) diagnosed OSA. All young children underwent pre-operative PSG followed by drug-induced sleep endoscopy (DISE) directed intervention. Variables documented included demographics, comorbidities, history of adenotonsillectomy, DISE directed surgical interventions and pre and post PSG findings. Laryngomalacia was defined as presence of obstruction (Chan Parikh score ≥ 2) at the supraglottic level on DISE evaluation. Demographics and prevalence of comorbidities of those with and without LM were compared using t-test (continuous) and Chi Square (categorical). P value is significant for <0.05.
RESULTS: 79 surgically naïve young children with PSG diagnosed OSA performed between 2015 and 2019 were included in the study. Children with LM were younger in age (11 months) and had a higher OSA-18 score (35) compared to children without LM (17 months) (OSA-18 score: 5). No significant difference was noted in the pre-DISE PSG parameters in the 2 groups. 56.1% of children with OSA and laryngomalacia did not need AT. Both children with and without laryngomalacia showed improvement in AHI on post-DISE PSG. Higher baseline AHI was associated with greater improvement in AHI.
CONCLUSION: Surgically naïve young children with OSA and LM present earlier than those without LM and report a significantly worse quality of life Young children with a higher baseline AHI were found to have greater improvement in severity of OSA post-DISE and surgical intervention. Majority of children with OSA and laryngomalacia did not need adenotonsillectomy after a preprocedural DISE assessment yet showed similar improvement in AHI. More studies are needed to determine which patients with OSA and laryngomalacia will need multilevel interventions.
