Abstract

Objective: evaluate the correlation between skeletal changes in 2D dimensions and volume changes of the upper airways before and after rapid maxillary expansion (RME) therapy in children with obstructive sleep apnoea (OSA) by Cone Beam computed tomography (CBCT) and between volume of the upper airways and clinical data.

Methods: 23 children with OSA and malocclusion underwent CBCT scans with a Dentascan and 3D reconstruction program before (T0) and 4 months after (T1) RME. Patients underwent an ENT visit with auditory and respiratory tests, including a daytime sleepiness questionnaire, a 19-channel polysomnography, and an orthognatodontic examination.

Results: in all cases opening of the mid-palatal suture was demonstrated. Nasal osseous width, volume of the total upper airways, nasal cavity and nasopharynx and oropharynx increased significantly (P, .05), and enlarged nasopharyngeal volume was correlated to increased nasal width at the PNS plane (P, .05). Posterior suture, pterygoideus process, maxillary width and Nasal cross-sectional width (PNS) (W-PNS) have an excellent and statistically significant correlation coefficient with Total upper airway volume (V-TA) Nasal cavity volume (V-NC) (Nasopharyngeal airway volume (V-NPA) Oropharyngeal airway volume (V-OPA), while Anterior and middle suture have an excellent and statistically significant correlation coefficient only with Oropharyngeal airway volume (V-OPA).
