Evaluation of infraorbital canal anatomy and related anatomical structures with Multi-Detector Ct

Results: IOC was observed as a groove, without a superior wall, rather than a canal in the majority of the images (64%). Presence of a true canal was observed in the 23% of the images. IOC coursed along the superior – lateral wall of the adjacent maxillary sinus in 83% of images (n = 408). IOF was single in 88% of images (n = 433). ASAC was detected in 44% of the images (n = 216). In comparison to IOC, ASAC had a lateral (n = 135, 62.5%) or inferior (n = 81, 37.5%) course. In the 72.6% of the patients presenting with ASAC, conjunction with IOC was detected just before the IOF.
