Trigeminal Nerve Blocks and Neurolysis

Trigeminal neuralgia is a chronic neuropathic pain syndrome that primarily involves the divisions of the fifth cranial nerve. The literature has shown that maxillary (V2) division is affected most frequently (50%), followed by the mandibular division (V3) (39%), and the ophthalmic division (V1) (11%). The trigeminal neuralgia is considered as the most common form of facial pain in people older than 50 years of age with an annual incidence of about 4.5 new patients per 100,000, significantly more common in women than men.
