The two dimensional plain cephalometric radiographs were widely used to assess the post-rapidmaxillary expansion (RME) effect on the naso-pharyngeal airway. However,volumetric changes inthe airway need proper assessment. The aim of this study was to assess the linear and volumetricchanges in the airway pre and post orthodontic RME using cone beam computed tomography(CBCT). A sample of 12 participants (8 males, 4 females with mean age 14+1.3) who needed RMEfor the management of posterior crossbite due to transverse maxillary deficiency was used in thisstudy. CBCT scans were acquired pre and post maxillary expansion. Linear and angular measurementswere calculated in addition to the volumetric measurements were obtained. There was astatistically significant increase in inter-molar width and molar tipping. The nasal cavity showedstatistically significant increase in the width of the nasal floor and the lateral nasal width. There wasalso statistical significant increase in naso and oropharygeal airway measurements post-expansion.RME using hyrax appliance increased the nasal floor width, nasal lateral width and the airway volumeat the naso and oropharyngeal level
