Effects of rapid maxillary expansion on nasal cavity dimensions and airway resistance

Relationship between rapid maxillary expansion and nasal cavity size and airway resistance: short- and long-term effects.

INTRODUCTION The availability of new, reliable, objective, and 3-dimensional techniques to assess the effects of rapid maxillary expansion on the morphology of the maxillary dental arch, nasal cavity dimensions, and nasal airway resistance led to the development of this research. METHODS Thirty-eight subjects participated in this study (mean age, 13 years). Data were collected before expansio...

The reduction of nasal airway resistance by rapid maxillary expansion and its effect on respiratory disease.

Effects of rapid vs slow maxillary expansion on nasal cavity dimensions in growing subjects: a methodological and reproducibility study.

AIM To evaluate the methodological feasibility of a RCT comparing skeletal changes of nasal cavity size obtained with RME and SME, assessed via CBCT. MATERIALS AND METHODS Twenty Caucasian children with a mean age of 10.4 years were recruited and allocated to receive RME (10 subjects, mean age 10.4 years) or SME (10 subjects, mean age 10.5 years). INCLUSION CRITERIA constricted maxillary ar...

Nasal airway measurements in children treated by rapid maxillary expansion.

BACKGROUND Rapid maxillary expansion is an orthodontic procedure that is commonly used to widen the maxilla. It is generally admitted that this technique is effective to correct palate narrowing, whereas there has not been agreement on the effect of this procedure in nasal parameters. The availability of a reliable and objective technique to assess the geometry of nasal cavities, such as acoust...

The effect of rapid maxillary expansion airway resistance onnasal

The purpose of this study was to evaluate changes in nasal resistance to ajrflow in persons undergoing rapid maxillary expansion and to reevaluate the responses at a l-year follow-up. Nasal resistance measurements, assessed in four modes (natural state, anterior nares dilation with Tygon tubing, following administration of decongestant, and nares dilation with tubing and decongestant), were tak...
