Foramen infraorbitale is a hole located on the anterior surface of maxilla through which nervus infraorbitalis, arteria infraorbitalis and vena infraorbitalis pass. The aim of this study is to evaluate the location of foramen infraorbitale and its distance from certain reference points on computed tomography (CT) images obtained by three-dimensional reconstruction method. In this study, maxillofacial CT images of 50 people who were examined in the facial region for any reason at Bulent Ecevit University Faculty of Medicine Radiology Department were used. The distance of foramen infraorbitale to eight reference points was measured. Two angles defined between the line drawn from the foramen infraorbitale to the two reference points and the vertical line drawn from the foramen infraorbitale to the midline were measured. With these data; side comparison was made amongst total people, women and men; gender comparison was made between the left and right sides. According to the side comparison, the distance between foramen infraorbitale and midline (MA) was found statistically significantly different in total people and men. In addition, the distance between foramen infraorbitale and apertura piriformis (AF) was statistically significantly different in women (p<0.05). According to the gender comparison, the distance between the foramen infraorbitale and the perpendicular line drawn from the outermost edge of arcus zygomathicus (AE) and the distance between the foramen infraorbitale and spina nasalis anterior (AH) was found statistically significantly different (p<0.05). On the right side, MA, AE, AF, AH and the distance between foramen infraorbitale and nasion (AG) was found statistically significantly different (p <0.05). As a result; knowledge of the location of foramen infraorbitale is important during the surgical interventions. Three-dimensional reconstruction studies related to the anatomical structures in this region are limited. CT can provide a detailed examination of the localization of foramen infraorbitale.
