“…The IOM is one of the most commonly used reference points. There was a wide range of values for the position of the IOF in relation to the IOM of the orbit, from 4 mm to over 10 mm [7][8][9], [11][12]. Our results were comparatively similar to that found in previous studies.…”

“…Various anatomical studies have been conducted with the aim to describe anatomical variations of the exit point of the infraorbital nerve and vessels from the orbit [6][7][8][9][10][11][12][13]. For a number of years, the research on the morphometry of the IOF has been realized on cadaveric or dry skulls.…”

“…Knowledge of distance IOF-IOM may be useful in identifying the position of the danger zone during surgical procedures. To apply an IONB, the surgeon needs to palpate the infraorbital margin to identify the IOF and then inject a local anesthetic [11]. However, palpating the IOM alone is not sufficient in locating the IOF in all cases.…”

“…Existing data concerning variations of the foramina related to the gender and side are still conflicting. Furthermore, large variations in measurements have been reported in the literature with regard to the distance between the IOF and other reference points on the face [6][7][8][9][10][11][12].…”

Abstract. In this study, we aimed to analyze the variability in the size and localization of infraorbital foramen (IOF) with respect to the surrounding anatomical bony landmarks using the three-dimensional computed tomography (3D-CT) with the volume rendering and evaluate these morphometric parameters in relation to the gender and side. The cranial CT scans of 60 living adult subjects, without any trauma or malformation of facial bones were included in the study. Data of the subjects were collected in the Center of Radiology, Clinical Center Nis, Serbia. Measurements included the transverse and vertical diameter of the IOF foramen, the distance from IOF to facial midline, the distance to lateral margin of the piriform aperture, the distance to infraorbital margin and the distance to maxillary alveolar border. All measurements were done bilaterally and performed with a digital coordinate caliper. Obtained results were statistically analyzed. Observation of 120 hemi-skulls revealed that the IOF was present in all of them. The mean transverse diameter of the IOF was 2.81 ± 0.69 mm and the mean vertical diameter was 3.41 ± 0.88 mm. The IOF was located at an mean distance 26.17 ± 1.69 mm from facial midline, 14.99 ± 1.30 mm from the lateral margin of the piriform aperture, 9.06 ± 1.01 mm below the IOM and 28.22 ± 2.78 mm above the maxillary alveolar border. Statistically significant difference was found between males and females for the distance from IOF to PA (p < 0.05). These morphometric characteristics may have important implications for the surgical and local anesthetic planning.

The aim of this study was to provide the morphological and morphometric data of the supraorbital foramina or notches related to sex, side, and the climatic conditions where the population lived. It was hypothesized that the distribution of the occurrence and location of these openings depends on climatic conditions in which the population lived. Orbits from 866 dried skulls obtained from three climatic regions: warm, temperate, and cold were examined. The examination concentrated on the configuration (notch/foramen) and on the distances to the reference points: nasion, frontomalare orbitale, infraorbital foramen and the superior orbital rim. In 14.3% of cases a smooth supraorbital rim was observed while different variants of the structures were observed in 85.7% of the cases. In cold climatic conditions, supraorbital foramina were found in the highest frequency (35.4%). In warm and temperate climates, the observed frequencies of supraorbital foramen were the lowest (18.8% and 19.9%, respectively). Frequency of supraorbital notches was the lowest of those skulls from a cold climate (44.0%) and the highest in those from a warm climate (59.0%). These results support the hypothesis that the occurrence of the supraorbital notches is greater in populations from warm compared with cold regions. This would provide a greater exit route for the neurovascular bundle and this may be related to the thermoregulatory processes in the supraorbital region. Furthermore, knowledge of precise locations of supraorbital structures is important when a supraorbital nerve block is given, for example, in the treatment of migraine headaches.

This study aimed to determine the number of infraorbital foramina in monkeys of the Papionini tribe. The authors performed a μCT analysis of the morphology of the infraorbital foramina. A total number of 52 simian skulls belonged to two macaque species: Macaca mulatta and Macaca fascicularis were used in the study. The number of infraorbital foramina was counted macroscopically and with the use of a magnifying glass. Next, the skull representing the most common morphological type was selected and scanned by micro‐computed tomography (μCT). The Shapiro–Wilk normality test was used in the study. To compare the differences in the number of infraorbital foramen between species, sex and sides, the Mann–Whitney U test was applied. Three infraorbital foramina were present in most individuals from the test group. The Mann–Whitney test revealed no statistically significant difference between the number of foramina on the right‐ and left‐hand side. Likewise, no statistically significant differences between the numbers of infraorbital foramina across sexes were observed. Volumetric reconstructions revealed the presence of separate infraorbital canals for each infraorbital foramen. Craniofacial innervation in macaques is formed by complex branching patterns of cranial nerves. Variability in the number of infraorbital foramina suggests a variable maxillary innervation pattern in these animals. Based on the analysis of volumetric projections, the presence of two labial branches and a single nasal branch of the infraorbital nerve is suggested. Detailed descriptions are supported by quantitative data and μCT evidence.
