Abstract

Retrusion of jaws was always associated with sleep apnea syndrome due to malpositioning of soft tissue structures and reduction of volume of the upper airway. Recently, transverse maxillary deficiency has received attention in the literature because it is a common find in the sleep apnea patients, beside being related to abnormal breathing patterns. Greater resistance to the airflow through the upper airways can be demonstrated in such individuals when compared with those presenting normal occlusion. Maxillary expansion procedures widening of the nasal floor and reduces resistance to airflow, with a positive influence upon naso-pharynx function and respiratory dysfunction. The objective of this study will be to prospectively evaluate the volume of the upper airway in 10 patients presenting with transverse maxillary deficiency treated with surgically assisted rapid maxillary expansion.
