In turn, it splits into two branches: Facial nerves: The final course of the maxillary nerve, after exiting the infraorbital foramen, sees the nerve divide into three sets of terminal branches: As with many parts of the nervous system, there are sometimes variations seen in the structure of the maxillary nerve, and this is of particular concern for surgeons and dentists. While compression by a blood vessel is one of the more common causes of trigeminal neuralgia, there are many other potential causes as well. It leaves the canal through the major palatine foramen and together with the artery, it courses medially and forwards to end in the area of the incisive fossa where it makes anastomosis with the contralateral major palatine nerve and with the nasopalatine nerve. Doctors may also cut part of the trigeminal nerve (neurectomy) during this procedure if arteries aren't pressing on the nerve. Radiofrequency thermal lesioning. Pain symptoms were found to be mediated by the maxillary division of the trigeminal nerve and resolved after percutaneous radiofrequency ablation (RFA) of bilateral maxillary nerves.

Surgeries repairing this nerve following trigeminal neuralgia are largely successful, with all three major approachesmicrovascular decompression, radiosurgery, and radiofrequency lesioninghaving success rates at or above 80%. Sensory information from these areas passes via axons to the trigeminal ganglion, located within an area called Meckels cave, a special pouch within the middle cranial fossa. These branches converge to form the sensory root of the trigeminal nerve and convey the sensory information to the brains at the level of the pons, a section associated with a range of bodily functions, such as sleep, breathing, swallowing, hearing, balance, among many others. Superior labial branches: There many of these smaller nerves, which serve to enervate the side of the cheek, the upper lip, oral mucosa, and labial glands (which help produce saliva).
