“…The branching pattern of the infraorbital nerve (ION) after its exit through the infraorbital foramen is another very welldocumented side of its anatomy, due to its importance in peripheral nerve blockade. Several cadaver studies focus on the prevalence of a true infraorbital channel versus an infraorbital groove [4,5]. Consulting Bergman's Comprehensive Encyclopaedia of Human Anatomic Variation, along with a literature search revealed a few distinct variants of the ION branching.…”

Anatomical variations are a common feature of the human anatomy. Variation can explain some pathological conditions and is important to keep them in mind during surgical procedures. The relations between nerves and their adjacent arteries have been proposed to play a role in the generation of peripheral trigger migraines. Close opposition between nerves and arteries can lead to vascular compression on the nerve that triggers episodes of pain. We did a routine dissection of the infratemporal fossa and orbital oor by opening the maxillary sinuous. Here we report a case where the infraorbital nerves form a nervous loop entrapping the infraorbital artery in the infraorbital channel. Similar cases of close nervous and arterial apposition are described for the auriculotemporal, and occipital nerves. We think that accumulating knowledge of these rare variations could expand our understanding of rare conditions such as primary infraorbital neuralgia.

“…The IOA commonly exits through IOF in the middle and superior (2) to the ION bundle within the same sheath (1). The ION could give off branches at various levels; at the beginning of infraorbital groove, along infraorbital canal or after emerging from IOF, and each branch can divide into subbranches differently (18). Hu et al (2007) found that inferior palpebral branch of the ION divided into medial and lateral branches (3), while the study of Nderitu et al (2014) reported only one branch of this nerve (19).…”

The infraorbital nerve block is commonly used for mid-facial anesthesia. Therefore, the location of infraorbital foramen (IOF) and accessory infraorbital foramen (AIOF) where the nerve exits through is important. Although, many studies tried to identify the location of IOF and AIOF using bony and soft tissue landmarks, the results varied in each study. Objectives�To determine the location of IOF and AIOF with reference to the line between anterior nasal spine (ANS) and the lowest point of the zygomaticomaxillary junction (Z) which is defined as line A, describe anatomical relationship between IOF and AIOF, and assess an accuracy of the proposed predicting method. Methods�A total of 216�skulls were examined. Live images were analyzed under the stereoscopic microscope. For localization of IOF, the vertical distance from IOF to line A (B) and the mean ratio of the distance between ANS and the intersecting point of the vertical line from IOF with line A (D) to distance A were analyzed. If AIOF was identified, all distances were measured similar to IOF. To assess an accuracy of the predicting method, 15 cadavers were studied by measuring the distance error between the predicted and�the real foramen. Results�There were 86 AIOFs. Most of them located superomedial to IOF except for 3 AIOFs which located in the inferolateral position. The location of IOF was predicted by using the vertical line B which was 15.14 ? 1.99 mm and the mean ratio of distance D to distance A (D:A) which was 63.35 ? 3.9%. For localization of AIOF, the mean vertical distance was 19.34 ? 3.36 mm and the mean ratio was 51.8 ? 5.9%. No statistically significant difference�was found between sex and sides. In cadavers, the mean distance error of the predicted IOF was 1.10 ? 1.44 mm lateral and 0.59 ? 1.39 mm inferior to the real IOF and there were 50% of the predicted IOFs that accurately located within the real IOF. Therefore, this study provides an alternative method for localization of IOF and AIOF which could be useful in clinical settings.
