Tic douloureux

Tic douloureux (trigerminal neuralgia) usually has its onset in the sixth or seventh decade and is characterized by severe, excruciating facial pain which is almost always unilateral. The mandibular division and the maxillary division of the fifth cranial nerve are most commonly affected. Carbamazepine is the drug of choice. Currently popular surgical procedures include decompression of the fifth cranial nerve and percutaneous thermal lesioning of the gasserian ganglion.
