The infraorbitalis is a prominent anatomical landmark located within the human face. Specifically, it refers to the infraorbital nerve and its corresponding infraorbital foramen, a small opening in the bone beneath the orbit of the eye. This nerve, a branch of the maxillary nerve, which itself originates from the trigeminal nerve, plays a crucial role in sensation for the lower eyelid, side of the nose, upper lip, and adjacent cheek.

The infraorbital foramen serves as the exit point for the infraorbital nerve and accompanying blood vessels from the infraorbital canal. This canal runs within the maxilla, the upper jawbone. The infraorbital nerve provides sensory innervation to the skin and mucous membranes of the aforementioned facial regions, allowing individuals to feel touch, pain, and temperature.

Clinically, the infraorbital foramen and the infraorbital nerve are significant in various medical and dental procedures. Local anesthetic injections are often administered near the infraorbital foramen to numb the areas supplied by the nerve, facilitating dental work on the upper teeth or minor surgical procedures on the lower face. Understanding the location and function of the infraorbitalis is essential for healthcare professionals involved in facial anatomy and procedures.
