Abstract:
Objective:To systematically evaluate the volumetric changes of upper airway after rapid maxillary expansion using Meta analysis.Methods:All literatures about volumetric changes in the upper airway after rapid maxillary expansion were searched from the database in general.The literatures were screened according to the correlation and the inclusion criteria,included the literatures were analyzed by Rev Man 5.3.Results:11 literatures were finally selected.Meta analysis indicated that,after treatment nasopharyngeal volume increased by 0.62 cm3(P=0.000 2),palatopharyngeal volume increased by 0.62 cm3(P=0.02),glossopharyngeal volume increased by 0.39 cm3(P=0.11),oropharyneal volume increased by 0.40 cm3(P=0.27).Conclusion:The existing evidence indicates that rapid maxillary expansion can increase the volume of nasopharynx and retropalatal part of upper airway.
