Trigeminal neuralgia (TN, or TGN), also known as prosopalgia, suicide disease, or Fothergill's disease, is a neuropathic disorder characterized by episodes of intense pain in the face, originating from the trigeminal nerve.
6. Treatment for TN
6.1 Medical Treatment： 6.1.1 Carbamazapine is the gold standard for initial
treatment.
6.3 Operation for TN:
6.3.1 Percutaneous procedures:

1. Definition of Trigeminal Neuralgia
2. Prevalence and Incidence
2.1 150,000 people are diagnosed with TN every year（annual occurrence is 35/100,000)
2.2 Over the age of 50 (52-69).
2.3 More common in women than in men （F/M，1.74/1).
The maxillary branch (V2) sensation covers the lower eyelid, the side of the nose, the upper lip and cheek, and the upper teeth and gums.
The mandibular branch (V3) is responsible for sensation of the lower teeth and gums, lower lip, chin, jaw, and part of the ear. It is also responsible for supplying the muscles involved with chewing (mastication), those muscles involved with chewing.

6.3.2 Open Surgery (MVD):
6.3.2.1 Theoretical Basis: 6.3.2.2 Preoperative evaluation:
3D MRI: 3D time of flight (3D- TOF) , 3D constructive interference in steady – state( 3D -CISS) , fast imaging employing steady- state acquisition (FIESTA).
5. Clinical characters of TN
5.1 Dermatome of TN
The ophthalmic branch (V1) is responsible for sensation from the scalp, forehead, upper eyelid and tip of the nose.
In 3D-TOF, signal of venous is isointensive.
The image of nerve in FIESTA stage is superior to it in 3D-TOF stage.
