Résumé
Objective:To evaluate volumetric changes in the upper airway after orthodontic-bimaxillary surgery for the treatment of skeletal class Ⅲ malocclusion.Methods:Literatures about volumetric changes in the upper airway after orthodontic-bimaxillary surgery for the treatment of skeletal class Ⅲ malocclusion were searched from the database:Cochrane library,Embase,PubMed,Web of Science,Wangfang,China Science and Technology Journal Database (VIP),Chinese Biomedical Medicine Database (CBM) and China National Knowledge Infrastructure(CNKI).All the literatures were evaluated by Newcastle-Ottawa Scale(NOS) and analyzed by RevMan 5.3.Results:9 studies with 204 cases about volumetric changes in the upper airway after orthodontic-bimaxillary surgery for the treatment of skeletal Ⅲ malocclusion were included.Meta-analysis showed that after treatment there was no statistical difference about the nasopharyngeal volume change and the total volume change(P＞0.05);there was statistically significant difference about oropharyngeal volume change (P＜0.05).Conclusion:It might be better to consider orthodontic-bimaxillary surgery for skeletal class Ⅲ malocclusion with certain risk factors about OSAHS,but there was still a risk of airway narrow after orthodontic-bimaxillary surgery for skeletal class Ⅲ malocclusion.
