Infraorbital fissure or groove is located on the floor of the orbit of the eye which is created by the superior portion of the maxilla. It anteriorly converts into the infraorbital canal. Essential branches of the fifth Cranial Nerve and vessels go inside this fissure and canal and produce branches within the canal, which supply some of the maxillary teeth as well as surrounding tissue. The infraorbital nerves and vessels leave the infraorbital canal inside the face from the infraorbital foramen.
