The present study assessed the 3D PAS changes following isolated mandibular advancement at a follow-up period of 1 year. A total of 120 patients (40 males, 80 females, mean age: 26.0 \u00b1 12.2) who underwent BSSO advancement surgery were recruited. Cone-beam computed tomography (CBCT) scans were acquired preoperatively (T0), immediately following surgery (T1), and at 1 year of follow-up (T2). The volume, surface area, and minimal cross-sectional area (mCSA) of the airway were assessed. The total airway showed a 38% increase in volume and 13% increase in surface area from T0 to T1, where the oropharyngeal region showed the maximum immediate change. At T1\u2013T2 follow-up, both volumetric and surface area showed a relapse of less than 7% for all sub-regions. The mCSA showed a significant increase of 71% from T0 to T1 (p &lt; 0.0001), whereas a non-significant relapse was observed at T1\u2013T2 (p = 0.1252). The PAS remained stable at a follow-up period of 1 year. In conclusion, BSSO advancement surgery could be regarded as a stable procedure for widening of the PAS with maintenance of positive space at follow-up.<\/jats:p>","DOI":"10.3390\/jimaging8040082","type":"journal-article","created":{"date-parts":[[2022,3,22]],"date-time":"2022-03-22T23:30:23Z","timestamp":1647991823000},"page":"82","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Three-Dimensional Pharyngeal Airway Space Changes Following Isolated Mandibular Advancement Surgery in 120 Patients: A 1-Year Follow-up Study"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6250-2650","authenticated-orcid":false,"given":"Sohaib","family":"Shujaat","sequence":"first","affiliation":[{"name":"OMFS IMPATH Research Group, Department of Imaging & Pathology, Faculty of Medicine, KU Leuven & Oral and Maxillofacial Surgery, University Hospitals Leuven, 3000 Leuven, Belgium"}]},{"given":"Eman","family":"Shaheen","sequence":"additional","affiliation":[{"name":"OMFS IMPATH Research Group, Department of Imaging & Pathology, Faculty of Medicine, KU Leuven & Oral and Maxillofacial Surgery, University Hospitals Leuven, 3000 Leuven, Belgium"}]},{"given":"Marryam","family":"Riaz","sequence":"additional","affiliation":[{"name":"Department of Physiology, Azra Naheed Dental College, Superior University, Lahore 54600, Pakistan"}]},{"given":"Constantinus","family":"Politis","sequence":"additional","affiliation":[{"name":"OMFS IMPATH Research Group, Department of Imaging & Pathology, Faculty of Medicine, KU Leuven & Oral and Maxillofacial Surgery, University Hospitals Leuven, 3000 Leuven, Belgium"}]},{"given":"Reinhilde","family":"Jacobs","sequence":"additional","affiliation":[{"name":"OMFS IMPATH Research Group, Department of Imaging & Pathology, Faculty of Medicine, KU Leuven & Oral and Maxillofacial Surgery, University Hospitals Leuven, 3000 Leuven, Belgium"},{"name":"Department of Dental Medicine, Karolinska Institutet, 17177 Stockholm, Sweden"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"416","DOI":"10.1108\/RPJ-10-2016-0163","article-title":"Mandibular retrognathia correction using a fixed sagittal guidance appliance individually manufactured by selective laser melting manufacturing technology","volume":"24","author":"Fekonja","year":"2018","journal-title":"Rapid Prototyp.
