  • Objectives: The objective of this study is to analyze cone-beam computed tomography (CBCT) images to measure changes in oropharyngeal airway (OPA) dimensions after treatment with rapid maxillary expansion (RME), and compare these changes with those from a matched control group. Methods: This randomized controlled clinical trial included an untreated matched control group of 38 subjects, and a treatment group of 37 subjects with maxillary transverse deficiency that received RME with a hyrax appliance. CBCT scans were taken at baseline and after 6 months and were analyzed for changes in OPA volume and cross-sectional area measurements. Results: A MANOVA revealed no significant changes in OPA volume and cross-sectional area measurements between subjects treated with RME compared to an untreated group over a 6 month time period. Conclusion: Treatment with a hyrax appliance did not yield a significant effect in changing OPA dimensions.
