Orbit
Published in Swati Goyal, Neuroradiology, 2020
The inferior orbital fissure, present between the floor and the lateral wall of the orbit, contains the inferior ophthalmic vein, the infraorbital artery, and the infraorbital nerve (a branch of the maxillary division of trigeminal nerve). The infraorbital foramen crosses the floor of the orbit and carries the infraorbital artery, vein, and nerve from the inferior orbital fissure.

The infraorbital artery takes its origin from the third part of the maxillary artery. It emerges through the infraorbital foramen to supply the lower eyelid, cheek, lateral nose and ipsilateral upper lip. The infraorbital artery has extensive communications with the trans-verse facial artery and branches of the facial artery and the ophthalmic artery.

Notable vasculature in this region include the infraorbital artery, angular artery, dorsal nasal artery, and zygomaticofacial artery (Figure 1). The infraorbital foramen, from which the infraorbital artery and nerve exit, is typically located medially 1/3 of the distance between the medial and lateral canthi, and on average between 6.3–10.9 mm below the infraorbital rim and is not reported to change significantly with age (6,7). The angular artery, a branch of the facial artery, courses along the medial periorbital area and anastomoses with the dorsal nasal artery here (6). This artery can have variations in location, and in some may be located more superficially in the subcutaneous tissue. The zygomaticofacial artery and nerve arise from a foramen at the lateral orbital rim about 0.5–1.0 cm below the horizontal line at the lateral canthus (8).
Oral mucosa grafting in periorbital reconstruction
Published in Orbit, 2018
Buccal mucosa is delimited by the outer commissure of the lips anteriorly, the anterior tonsillar pillar posteriorly, the maxillary vestibular fold superiorly, and the mandibular vestibular fold inferiorly. Vascular supply is derived predominantly from branches of the maxillary artery. These include the buccal artery, the middle and posterior superior alveolar arteries, and the anterior superior alveolar branch of the infraorbital artery. The transverse facial artery, a branch of the superficial temporal artery provides additional blood supply. Buccal mucosa is innervated by the long buccal nerve, a branch of the third division of the trigeminal nerve (CNV3) and the anterior, middle, and posterior superior alveolar branches of the second division of the trigeminal nerve (CNV2). The facial nerve also contributes sensory innervation to the buccal mucosa.74,75
Angular artery island flap for eyelid defect reconstruction

All these studies show that angular artery is a continuation of facial artery in only half of the cases. Hou et al. examined 22 hemi-faces and found that the angular artery was constantly present in their specimens and it originated from an ophthalmic or infraorbital artery in about 64% of the specimens [22]. Based on the findings of these mentioned studies, the flow was not reversed at least half of the cases so the term ‘retroangular flap’ is not appropriate. The flap can be named as angular artery axial flap instead.
