The osteotomies and subsequent spatial rearrangement of the maxilla and the mandible enable the correction of facial deformities, asymmetry, and malocclusion. Moreover, the movements performed during the procedure affect the morphology of surrounding soft tissues, including the upper airway (UA). Objectives: The objective of this study was to radiologically assess the potential volumetric alterations of the UA in the supine position at various intervals following BiMax advancement surgeries. Methods: A group of 31 patients who underwent BiMax advancement surgery were included in the study. Medical computed tomography (CT) of the head and neck region was performed 2 weeks preoperatively, 1 day postoperatively, and 6 months postoperatively. The UA volumes were calculated and analyzed based on the acquired Digital Imaging and Communications in Medicine (DICOM) files using different software applications. The sella-nasion-A point (SNA) and sella-nasion-B point (SNB) angles were evaluated to measure the achieved maxillomandibular advancement. Results: When comparing the volume of the UA before surgery, post-surgery, and 6 months post-surgery, the p-value was &lt;0.001, indicating statistically significant differences in UA volume between the successive examinations. A statistically significant difference was found between UA volume before surgery and 6 months post-surgery and between UA volume after surgery and 6 months post-surgery, with the obtained p-values being &lt;0.001 and 0.001, respectively. A significantly larger UA volume was observed 6 months post-surgery (mean \u00b1 SD: 27.3 \u00b1 7.3) compared to the volume before surgery (mean \u00b1 SD: 22.2 \u00b1 6.4), as well as 6 months post-surgery compared to the volume assessed shortly after surgery (mean \u00b1 SD: 24.2 \u00b1 7.3). Conclusions: BiMax advancement surgeries result in the significant enlargement of the UA. The volume of the UA does not diminish immediately following the procedure and is not constant; it increases significantly during the postoperative observation period.<\/jats:p>","DOI":"10.3390\/jcm13164588","type":"journal-article","created":{"date-parts":[[2024,8,6]],"date-time":"2024-08-06T08:07:59Z","timestamp":1722931679000},"page":"4588","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Assessment of Upper Airway Volume Changes Following Bimaxillary Advancement Surgery: A Radiological Evaluation in the Supine Position at Multiple Intervals"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0349-9914","authenticated-orcid":false,"given":"Pawe\u0142 Piotr","family":"Grab","sequence":"first","affiliation":[{"name":"Clinical Department of Cranio-Maxillo-Facial Surgery, Military Institute of Medicine\u2014National Research Institute, Szaser\u00f3w 128, 04-141 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Micha\u0142","family":"Sza\u0142wi\u0144ski","sequence":"additional","affiliation":[{"name":"Clinical Department of Cranio-Maxillo-Facial Surgery, Military Institute of Medicine\u2014National Research Institute, Szaser\u00f3w 128, 04-141 Warsaw, Poland"},{"name":"Department of Dental and Maxillofacial Radiology, Medical University of Warsaw, 02-097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maciej","family":"Jagielak","sequence":"additional","affiliation":[{"name":"Ortognatyka Dr Jagielak\u2014Private Surgical Practice, Al.
