The infraorbital foramen is located immediately below the inferior border of the orbit and contains the infraorbital artery and infraorbital nerve (Figure 7.2). The infraorbital artery originates as a branch of the maxillary artery and anastomoses with the facial artery following its emergence through the infraorbital foramen. The infraorbital nerve is a terminal branch of the maxillary nerve (CN V2). It resides beneath the quadratic labii superioris and provides sensory innervation to the lower portion of the eyelid, the upper lip, and the lateral portion of the nose.
