Insights
Children with Robin sequence have a higher risk of obstructive sleep apnea (OSA) and behavioral issues. Early OSA treatment in infancy is linked to normal neurocognitive outcomes in primary school-aged children.
Area of Science:
- Pediatric Sleep Medicine
- Craniofacial Abnormalities
- Neurodevelopmental Disorders
Background:
- Robin sequence (RS) is a congenital condition affecting facial development, often associated with airway obstruction.
- Obstructive sleep apnea (OSA) is a common complication in children with RS, potentially impacting long-term health.
- Early intervention with devices like the Tuebingen palatal plate aims to manage RS-related airway issues.
Purpose of the Study:
- To evaluate neurocognitive and behavioral outcomes in primary school-aged children with RS.
- To investigate the prevalence and impact of obstructive sleep apnea (OSA) in this cohort.
- To assess the effectiveness of early palatal plate treatment on long-term outcomes.
Main Methods:
- A cohort of 42 primary school-aged children (21 with RS, 21 controls) underwent polysomnography.
- Intelligence was assessed using the Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V).
- Sleep habits and behavior were evaluated through sleep diaries, CSHQ, and CBCL questionnaires.
Main Results:
- Children with RS exhibited a significantly higher obstructive apnea-hypopnea index (OAHI) compared to controls.
- Despite normal overall intelligence quotient (IQ) scores, children with RS showed increased risk for externalizing behavioral problems.
- One child with RS was diagnosed with severe OSA (OAHI 57/h) despite a previously unremarkable history.
Conclusions:
- Children with Robin sequence face an elevated risk for OSA and associated behavioral challenges.
- Regular OSA screening is recommended throughout childhood for individuals with RS.
- Adequate treatment of OSA during infancy supports normal neurocognitive development in children with RS.
Study Objectives:
To investigate neurocognitive and behavioral outcomes at primary school age in relation to obstructive sleep apnea (OSA) in children with Robin sequence (RS) treated with the Tuebingen palatal plate in infancy and to assess the impact of OSA in these patients.
Methods:
Forty-two primary school-aged children (n = 21 with RS, n = 21 age- and sex-matched controls) underwent polysomnography, intelligence testing ("Wechsler Intelligence Scale for Children-Fifth Edition" [WISC-V]), and anthropometrics. Families completed a 7-day sleep diary and questionnaires on sleep and behavior (Children's Sleep Habits Questionnaire [CSHQ] and the Child Behavior Checklist [CBCL]).
Results:
In children with RS (17 non-syndromic, four syndromic; median age 9.7 [8.5-10.8] years), the obstructive apnea-hypopnea index (OAHI) was significantly higher than in controls (1.3 [0.4-2.7]/h vs. 0.4 [0.1-0.6]/h). Two syndromic children with RS were already on nocturnal respiratory support for OSA prior to our study, and one non-syndromic child was diagnosed with severe OSA (OAHI 57/h) despite an unremarkable medical history and questionnaire. The overall intelligence quotient in children with RS was within the normal range and did not differ between children with RS and healthy peers (102 vs. 108, p = .05). However, children with RS had values in the at-risk clinical range for externalizing behavior.
Conclusions:
These children with RS showed an increased risk of OSA and behavioral problems, suggesting regular screening for OSA throughout childhood. Neurocognitive scores in children with RS were within the normal range after adequate treatment of OSA during infancy.
