“…Hence, headshaking has been suggested to be due to neuropathic pain. There is a long‐standing comparison between idiopathic headshaking and trigeminal neuralgia, a neuropathic pain syndrome in humans; compression of the trigeminal nerve as seen on MRI in human patients is a commonly stated cause of trigeminal neuritis …”

Headshaking is a common problem in horses. The etiology is unknown but thought to involve sensory input from branches of the trigeminal nerve, some of which are within the infraorbital canal.The objective of this retrospective cross-sectional study was to describe the CT anatomy and variations of the infraorbital canal in horses with local disease processes and normal horses, and to examine associations between those findings and headshaking. Computed tomography scans were reviewed and morphological changes of the infraorbital canal were described. Presence of changes was then tested for association with headshaking prevalence, presence of disease processes in the region of the infraorbital canal, age, and sex. Nonparametric tests were used and a P-value of .05 was considered significant. A total of 218 horses were included, 9% of which had headshaking and 45% had CT lesions in the region of the infraorbital canal. Morphological changes to the bone of the infraorbital canal were found in 121 horses (56%) and included the following: increased mineralization 39 (18%), decreased mineralization 89 (41%), deformed shape 51 (23%), displaced position 43 (20%), and disruption 11 (5%). All changes of the infraorbital canal significantly increased in frequency with the presence of adjacent disease. Increased mineralization and disruption of the infraorbital canal were significantly associated with headshaking in horses with adjacent disease; the latter only reached significance after exclusion of dentally immature horses.No other changes were significantly associated with the presence of headshaking. No association was found between headshaking and the age or sex of the horse. K E Y W O R D Sequine head, maxillary, neurological, sinusitis, trigeminal nerve

“…The first one involves experimental procedures carried out on cadaveric and dry skulls [3][4][5][6][7][8][9][10][11][12]. The second one involves the evaluation of cranial structures by MDCT [13]. The findings of the previous studies that used cadaveric skulls and dry skulls showed the variability of size and position of IOF.…”

“…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.…”

“…As far as we know, there's only one similar study conducted on living subjects. Hwang et al [13] examined variations of IOG, IOC and IOF on 100 living subjects using MDCT and evaluated the obtained results according to the gender and side. Their results showed that the mean distances IOF-IOM and IOF-FML were 9.6 ± 1.7 mm and 26.5 ± 1.9 mm, respectively.…”

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.

“…A clear understanding of facial anatomy is critical to avoid a catastrophic complication, such as inadvertent vessel cannulation. The principal facial foramina and large periocular vessels can be accurately localized using the patient’s pupil as a global positioning system: the supraorbital vessels are aligned with the medial iris limbus, and the infraorbital vessels fall between the pupil and the medial iris 32–34 (Fig. 4).…”

Morphometric analysis of the infraorbital groove, canal, and foramen on three-dimensional reconstruction of computed tomography scans

Abstract: These results provide detailed knowledge of the anatomical characteristics and clinical importance of the IOF. Such knowledge is of paramount importance for surgeons when performing maxillofacial surgery and regional block anesthesia.
