Abstract

This study examined the effects of Rapid Maxillary Expansion (RME). Using Cone Beam CT scanning technology and Rhinomanometry, the volume and nasal airway resistance (NAR) of the nasal cavity was measured immediately before and after RME.

27 subjects (16 female, and 11 male), ages 9-18 were enrolled in the study. After RME all subjects had a statistically significant increase in nasal cavity volume. The pre expansion group experienced a statistically significant reduction in NAR when compared to the post expansion group. Individuals with a high pre expansion NAR experienced the greatest reduction in NAR. The correlation between change in volume and change in NAR proved to be weak. A comparison was made among facial types; Dolichofacial individuals experienced a greater reduction in NAR to the other face types, especially when compared to Brachyfacial individuals.
