What does infraorbital mean?
Infraorbital is an anatomical adjective meaning below the eye socket, or relating to structures in that region. The orbit is the bony cavity that contains the eye, so the prefix infra- specifies a position beneath it. In medicine, the term is used especially for the infraorbital nerve, artery, foramen, and region. It is more precise than informal expressions such as “under the eye” and is usually found in clinical descriptions, surgical procedures, and anatomical references. Although relatively uncommon in general conversation, it is useful when distinguishing structures around the eye and in understanding how nerves and blood vessels pass through the facial skeleton.

Infraorbital literally means “below the orbit”: orbit refers to the eye socket, and infra- means beneath.

Where does infraorbital come from?
Infraorbital was formed in English from the Latin prefix infra-, meaning “below,” and orbitalis, meaning “pertaining to the orbit” or “eye socket.” The compound reflects the traditional anatomical description of structures situated beneath the orbit. Its roots are shared by related English words such as infra, orbital, suborbital, and supraorbital, which distinguish positions below and above the eye socket.
How infraorbital is actually used
This is a specialized anatomical term. It is normally used in medical, anatomical, and surgical contexts and is not generally used in everyday speech. British and American medical usage generally agree on its meaning and form.
