Cranial Nerve Disorders - Overview
A cranial nerve disorder typically affects a single cranial nerve, as in trigeminal neuralgia (TN), Bell's palsy, hemifacial spasm (HFS), and glossopharyngeal neuralgia (GPN).

Neurosurgical treatments include microvascular decompression (MVD) surgery, a non-destructive procedure, and various rhizotomies, whereby nerve tissue is destroyed in order to alleviate pain and suffering in the patient.
