Turk Arch Otorhinolaryngol. 2023 Sep;61(3):134-137. doi: 10.4274/tao.2023.2023-3-4. Epub 2023 Nov 14.

Abstract

The infraorbital nerve is responsible for the sensory innervation of the lower eyelid, the lateral nose, the cheek, the upper lip, and the maxillary teeth. It passes along the infraorbital canal, which runs superior to the maxillary sinus. Dehiscence of the infraorbital canal and its ectopic course in the maxillary sinus is a rare variation. A nerve with these variations may be affected by pathologies in the maxillary sinus and this may constitute a rare cause of facial pain. In this report, we present the clinical symptoms of a 29-year-old male patient who had an infraorbital nerve with an ectopic course and dehiscence in light of the literature.
