Preliminary short-term outcomes of rapid maxillary expansion on periodic limb movements during sleep in pediatric sleep-disordered breathing.

Objective: To assess the short-term outcome of rapid maxillary expansion (RME) on periodic limb movement disorder (PLMD) in children with residual snoring after late adenotonsillectomy (AT).

Methods: This prospective clinical trial included 24 patients treated with rapid maxillary expansion (RME). Participants' inclusion criteria were children with maxillary constriction aged 5-12 years who had AT for more than two years and those whose parents/guardians reported that they still snored ≥4 nights per week.
