Related to microvascular decompression: trigeminal neuralgia

microvascular decompression

A procedure for reducing cranial nerve compression by vessels within the cranial cavity.
 
Indications
Hemifacial spasm, glossopharyngeal neuralgia, trigeminal neuralgia.

Method
A corridor is cut along the petrous temporal bone and arachnoid around the neurovascular structures to reduce cranial nerve pressure; arteries and some veins are rerouted with stents, while minor compressive veins are electrocauterised. It may be useful for managing trigeminal neuralgia.

Conclusion: compression by an artery is the most common pathology encountered in the microvascular decompression for trigeminal neuralgia.
When medicinal treatment is no more effective various surgical modalities can be tried which include peripheral procedures like glycerol and alcohol injections, cryosurgery, peripheral neurectomy and central procedures viz microvascular decompression, radio frequency thermocoagulation, glycerol gangliolysis, balloon compression, percutaneous retrogasserian glycerol rhizotomy and gamma knife radiosurgery10.
Surgical methods include nerve section and microvascular decompression. The latter can provide complete relief of pain in 76% of patients and substantial improvement in an additional 16%, according to Resnick et al.
