Oropharyngeal changes caused by orthognathic surgery have been a concern because the sleep quality of patients may be enhanced or worsened by these changes. The purpose of this meta-analysis was to identify, review and compare scientific literature about changes in airway in adult patients undergoing orthognathic surgery to correct anteroposterior osseous discrepancies. An electronic search of four databases was carried out up to July 2010, with supplemental hand searching of the references of the retrieved articles. Quality assessment of the included articles was carried out. Data were extracted and a meta-analysis was performed. Heterogeneity was assessed amongst the studies and results were presented in forest plots. 49 studies met the inclusion criteria. Only studies with moderate or high methodological soundness were included in the review. Moderate evidence was found to support a significant decrease in the oropharyngeal airway in mandibular setback surgery, a milder decrease in bimaxillary surgery to correct Class III and an increase in maxillomandibular advancement surgery. Evidence is lacking on airway volume changes after orthognathic surgery.
正颌手术后的口咽变化一直是人们关注的问题，因为这些变化可能会改善或恶化患者的睡眠质量。本荟萃分析的目的是识别、回顾和比较有关成人正颌手术矫正前后骨性不调时气道变化的科学文献。截至 2010 年 7 月，我们对四个数据库进行了电子检索，并对检索到的文章的参考文献进行了补充手工检索。对纳入研究的质量进行了评估。提取数据并进行荟萃分析。评估了研究之间的异质性，并以森林图形式呈现结果。有 49 项研究符合纳入标准。仅纳入了方法学质量为中等到高的研究进行综述。有中度证据支持下颌后退手术中咽气道显著减小，III 类错颌矫正的双颌手术中轻度减小，上颌骨和下颌骨前突手术中增加。正颌手术后气道容积变化的证据不足。
