Are multi-detector computed tomography and cone-beam computed tomography exams and software accurate to measure the upper airway? A systematic review

CONCLUSIONS: MDCT and CBCT scans' accuracy in upper airway dimensional measurements depends on machine brand, parameters, and segmentation technique. Regarding the segmentation technique, 12 programs were studied. Most either underestimated or overestimated upper airway measurements. In particular, OnDemand3D and INVIVO showed poor accuracy. On the contrary, Invesalius, and MIMICS were accurate in assessing nasal cavities when using an interactive threshold. However, results varied due to methodological differences among the studies. Finally, fully automatic segmentation based on artificial intelligence may represent the future of airway segmentation because it is faster and seems to be accurate. However, further studies are necessary.REGISTRATION: This study was registered in Prospero (International Prospective Register of Systematic Reviews) with the ID number CRD42022373998.PMID:37797294 | DOI:10.1093/ejo/cjad060
