What is the location of trigeminal neuralgia?

    Under normal circumstances, trigeminal neuralgia primarily occurs within the distribution area of the trigeminal nerve, including parts of the face, oral cavity, and top of the head. Trigeminal neuralgia is a disorder involving severe facial pain, usually affecting one side of the face. The trigeminal nerve has three major branches: the ophthalmic nerve, maxillary nerve, and mandibular nerve. If discomfort symptoms arise, it is recommended to seek timely medical consultation at a hospital and follow standardized treatment under a physician's guidance. Detailed analysis is as follows:

    The ophthalmic nerve is distributed across areas including the anterior scalp of the skull, forehead, bridge of the nose, skin of the upper eyelid, upper nasal cavity, cornea, and conjunctiva. The pain mainly occurs around the forehead and eyes, including regions such as the eyebrow area and the temple. Some patients may also experience pain in or around the eye.

    The maxillary nerve supplies skin between the eye and the mouth opening, upper lip, upper jaw teeth and gums, hard and soft palate, anterior part of the tonsillar fossa, nasal cavity, maxillary sinus, and nasal pharyngeal mucosa. Pain mainly occurs around the ala nasi (nostril wing), upper lip, zygomatic region, and along the superior alveolar nerves, including areas near the incisors and adjacent lateral incisors.

    The mandibular nerve is distributed in the auriculotemporal region and the skin below the mouth opening, teeth and gums of the mandible, the anterior two-thirds of the tongue, floor of the mouth mucosa, external auditory canal, and tympanic membrane. Pain typically occurs in the lower jaw and the nerve distribution area, including the cheek and tongue regions.

    If pain occurs in any of the above-mentioned areas, it is recommended to promptly visit a qualified hospital for professional diagnosis and treatment by a physician.
