The distance between the infraorbital nerve (ION) entry point and the orbital rim was significantly smaller in the inferior lateral wall fracture group than in the MWF group (11.87 ± 2.54 vs 14. Infraorbital canal. Infraorbital groove. Maxillary part of orbital margin. Anterior surface of maxilla. Infratemporal surface of maxilla. Nasal surface of maxilla. Greater palatine groove of maxilla. Sinus of maxilla. Frontal process of maxilla. BACKGROUND AND PURPOSE: The infraorbital nerve arises from the maxillary branch of the trigeminal nerve and normally traverses the orbital floor in the infraorbital canal. Sometimes, however, the infraorbital canal protrudes into the maxillary sinus separate from the orbital floor. We systematically studied the prevalence of this variant.
