The orthognathic surgical correction of mandibular deviation compensates to some extent for the reduction in the cross-sectional area and volume of the upper airway caused by the surgery itself.</p><p><strong>Clinical relevance: </strong>For patients with skeletal Class III high-angle malocclusion with mandibular deviation, a thorough assessment of the upper airway should precede the selection of orthognathic surgery procedures. For patients with normal preoperative upper airway morphology, consideration may prioritize correction of facial aesthetics and occlusion. For patients with pre-existing narrow upper airways, as mandibular setback exacerbates narrowing and the compensatory effect of mandibular deviation correction on the airway is limited, it is suggested that these patients prioritize bimaxillary surgery or reduce the amount of mandibular setback to better promote postoperative respiratory function health.</p>","PeriodicalId":10461,"journal":{"name":"Clinical Oral Investigations","volume":"29 1","pages":"73"},"PeriodicalIF":3.1,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143001321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
