Screening for symptoms of obstructive sleep apnea in children with severe craniofacial anomalies: assessment in a multidisciplinary unit.

Objective: To assess the incidence of airway obstruction symptoms and the presence of obstructive sleep apnea in children with severe craniofacial anomalies by a proactive screening program using a standard questionnaire and cardiorespiratory polygraphy.
Patients and Methods: Children with severe craniofacial anomalies referred to our paediatric airway unit from February 2001 to June 2011 were eligible to be included in this retrospective, single centre study. Symptoms of airway obstruction were proactively investigated using the shorter version of the Pediatric Sleep Questionnaire (PSQ). Obstructive sleep apnea was assessed by means of cardiorespiratory polygraphy. Demographic data and reason for referral were also recorded. Primary outcomes were the prevalence of symptoms of airway obstruction and OSA.
Results: 44 children (24 girls) with severe craniofacial anomalies (15 Crouzon, 13 Apert, 9 Goldenhar, 5 Treacher-Collins, 2 Pfeiffer) were included, at a mean age of 5 years (range 8 months to 14 years). Reason for referral was routine follow up in 30 patients and overt OSA symptoms and signs in the remaining 14. PSQ results showed symptoms of airway obstruction in 82% of patients, being snoring the most frequent symptom (64.1%) followed by apneas (33.3%). Polygraphic studies showed inconclusive results in 8 children (18.2%), normal apnea-hypopnea index (AHI) in 16 (36.4%), mild obstructive sleep apnea in 9 (20.4%), moderate in 4 (9.1%) and severe obstructive sleep apnea in 7 (15.9%).
Conclusions: Children with craniofacial anomalies have a high prevalence of symptoms of airway obstruction and obstructive sleep apnea that support a proactive screening strategy in this highly selected population.
