The objective of this study was to evaluate the airway volume of growing patients combining a morphological approach
using cone beam computed tomography associated with functional data obtained by polysomnography examination after rapid maxillary
Study design: 22 Caucasian patients (mean age 8.3 0.9 years)
undergoing rapid maxillary expansion with Haas type expander banded on second deciduous upper molars were enrolled for this
prospective study. Cone beam computed tomography scans and polysomnography exams were collected before placing the appliance
(T0) and after 12 months (T1). Methods: Image processing with airway volume computing and analyses of oxygen saturation and
apnoea/hypopnoea index were performed.
Airway volume, oxygen saturation and apnea/hypopnea index underwent
significant increase over time. However, no significant correlation was seen between their increases.
maxillary expansion treatment induced significant increases in the total airway volume and respiratory performance. Functional
respiratory parameters should be included in studies evaluating the RME treatment effects on the respiratory performance.
