Introduction: The purpose of this study was to use cone-beam computed tomography to quantitatively evaluate the skeletal effects of rapid maxillary expansion and orthodontic treatment, with a specific interest in evaluating whether the skeletal changes achieved by RME will maintain throughout orthodontic treatment. Methods: Thirty consecutive patients (16 boys, 14 girls; mean age, 13.9 ± 1.8 years) who required RME with Hyrax appliances as part of their comprehensive orthodontic treatment were studied. Measurements before and after RME, and after orthodontic treatment, of palatal and buccal maxillary widths, palatal alveolar angle, nasal width, nasal floor width, and maxillary sinus width at …
