The syndrome is characterized by myotonia, skeletal dysplasia, and facial dysmorphism. Methods: CPAP was initially prescribed, but he was not able to tolerate due to a high pressure setting. Rapid maxillary expansion alone reduced AHI to 10.4 events/h. Results: When combined with CPAP, AHI is further reduced to 2.4 events/h. The patient has a better compliance with CPAP following rapid maxillary expansion therapy as the pressure setting decreased. Conclusions: This is the first report utilizing a combination of rapid maxillary expansion and CPAP therapy to successfully treat severe pediatric OSA.Mahidol UniversityMedicineNeuroscienceArticleSCOPUS10.5664/jcsm.9028
