Improvement in obstructive sleep apnea in a child with Down syndrome with rapid palatal expansion

Children with Down syndrome (DS) have distinct orofacial structures that predispose them to sleep-disordered breathing. The management options for obstructive sleep apnea include continuous positive airway pressure, adenotonsillectomy, mandibular advancement, and maxillary expansion. However, most of these treatment options are less effective or less viable for children with DS. Rapid maxillary expansion with a fixed orthodontic appliance is a viable alternative for DS patients because it separates the midpalatal suture and dilates the airway, regardless of the patient's compliance. We present a case of a 15-year-old boy with DS and severe obstructive sleep apnea, which dramatically improved with rapid maxillary expansion and subsequent orthodontic treatment. Although only the short-term changes have been presented in this report, this case emphasizes the need for further discussions on the viability of rapid maxillary expansion for treating obstructive sleep apnea in children with DS.
