infraorbital nerve

in·fra·or·bit·al nerve

[TA]
the continuation of the maxillary nerve [CN V2] after it has traversed the pterygopalatine fossa and enters the orbit, via the infraorbital fissure, it is then transmitted by the infraorbital canal to reach the face; it supplies the mucosa of the maxillary sinus, the upper incisors, canine and premolars, the upper gums, the inferior eyelid and conjunctiva, part of the nose, and the superior lip.
Synonym(s): nervus infraorbitalis [TA]

infraorbital nerve

The terminal branch of the maxillary nerve (CN V2). It is a sensory nerve that leaves the floor of the orbit through the infraorbital foramen and innervates the upper incisors and canine teeth, the mucosa of the maxillary sinus, and the skin of the lower eyelid, cheek, side of the nose, and upper lip.

In this article, we describe a case in which an unusual anatomic variation of the infraorbital nerve was observed.
The CT identified an unusual anatomic variation: The right infraorbital nerve canal passed through the lumen of the maxillary sinus within the lamella of an infraorbital ethmoid (Haller's) cell (figure).
Care was taken to preserve the bone of the infraorbital nerve canal, and the procedure was completed without complications.

In our patient, the infraorbital nerve canal traversed the lumen of the maxillary sinus within the lamella of the infraorbital ethmoid cell rather than coursing within the bone of the orbital floor.
