Trigeminal neuralgia (or tic doloreux∗) is a disorder of the sensory root of the trigeminal nerve
most common in middle-aged and elderly people
associated with the maxillary division (less frequently in the
mandibular division and least in the ophthalmic division)
.
The cause of trigeminal neuralgia is unknown, but may be due to an aberrant blood vessel
-surgical displacement of such vessels has relieved symptoms. -temporary block of the infraorbital nerve by
injection of alcohol.
- branches of the infraorbital nerve may be surgically transected or
avulsed at the foramen, or ablated using selective radio frequencies from a needle electrode passed
through the foramen ovale.
- sensory root may be partially cut between the ganglion and pons
(rhizotomy), or the spinal tract sectioned (tractotomy). S
