Rapid maxillary expansion improves airway and gives ample room for the tongue
This study: Does rapid maxillary expansion affect nasopharyngeal airway? A prospective Cone Beam Computerised Tomography (CBCT) based study, written by Mohammed Almuzian, Xiangyang Ju, Anas Almukhtar, Ashraf Ayoub, Lubna Al-Muzian, Jim P McDonald states:
Rapid maxillary expansion (RME) was found to be an effective dentoalveolar expander and significantly augment the upper nasopharynx and minimize the upper retropalatal space. Rapid maxillary expansion (RME) is a procedure used for midpalatal suture opening by means of fixed orthodontic appliances, during growth. The aim is to increase the transverse width of the maxillary arch as the result of dental and skeletal expansion. Bonded RME is an efficient dentoalveolar expander in growing patients and associated with an expansion of both LNC and upper nasopharynx spaces. The effects of RME on the upper nasopharyngeal region exhibited a mushroom-like pattern where the upper part expanded, the middle part significantly narrowed, and the lower part mildly but insignificantly narrowed. This form of interceptive orthodontics improves the nasal airway and gives ample room for the tongue. This study shows volumteric changes in the size of airway using Cone Beam Computerised Tomography (CBCT).
