Volumetric upper airway changes after rapid maxillary expansion: a systematic review and meta-analysis.

Background Although Rapid Maxillary Expansion (RME) has been used for over a century, its effect on upper airways has not yet adequately been assessed in an evidence-based manner. Objective To investigate the volumetric changes in the upper airway spaces following RME in growing subjects by means of acoustic rhinometry, three-dimensional radiography and… CONTINUE READING
