• Objectives: The objective of this thesis was to analyze cone beam computed tomography (CBCT) images to measure potential changes in nasal septal deviation (NSD) from rapid maxillary expansion (RME) treatment in a sample of adolescent patients.

  Methods: This retrospective study involved 26 patients that incidentally presented with mild to severe septal deviation and treated for transverse maxillary constriction with RME. A control group of 7 patients was also identified without RME treatment that presented with mild to severe baseline deviation. CBCT images were taken at T1 (before appliance insertion) and T3 (6 months after appliance removal) and were analyzed to measure changes in nasal septal deviation.

  Results: Repeated measures ANOVA and non-parametric Wilcoxon related samples test resulted in no significant changes in NSD with or without RME treatment and irrespective of baseline deviation.

  Conclusion: Rapid maxillary expansion treatment did not result in significant changes in NSD.
