A
neurovascular compression is described as a prominent pathological contact
between cranial nerves and vessels. This contact builds up in the so-called
root entry zone of a cranial nerve, where we find the transition of central
to peripheral myelin resulting in less myelination of nerve fibres (axon).
This region varies in length depending on the different cranial nerves and is
located close to the brainstem. This results in typical hyperactive
dysfunction of the respective cranial nerve. The trigeminal neuralgia, the
spasmus hemifaciei (hemifacial spasm) and the glossopharyngeal neuralgia are
typical clinical entities associated with neurovascular compression as the
predominant cause.
