Sleep-related breathing disorders in young orthodontic patients

Introduction: This study aimed to find out the frequency of sleep-related breathing disorders (SRBD) in young orthodontic patients in Israel. SRBD is characterized by prolonged upper airway obstruction during sleep. Methods: The study group consisted of 309 children aged 6-17 years who attended the Orthodontic Clinic at Hadassah Medical Center. Parents were asked to complete a translated validated Pediatric Sleep Questionnaire. Results: Of the examined children, 10% were at high risk for SRBD. Boys were at higher risk for SRBD and were at high risk at a younger age than girls. Girls had a low risk of SRBD after adenotonsillectomy, whereas 50% of the boys that underwent adenotonsillectomy were at high risk for SRBD. Conclusions: Our findings propose that 10% of the children aged 6-17 years, who were seeking orthodontic consultation at our medical center, were at high risk for SRBD. Boys were significantly at a higher risk for SRBD than girls and were at high risk at a younger age. It is important to screen young orthodontic patients for SRBD and to refer high-risk patients to their physicians for further evaluation and treatment.
