microvascular decompression(redirected from Jannetta procedure)
microvascular decompressionA procedure for reducing cranial nerve compression by vessels within the cranial cavity.
Hemifacial spasm, glossopharyngeal neuralgia, trigeminal neuralgia.
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.
