Hemifacial Spasm

Hemifacial spasm denotes a one-sided, painless, synchronous contraction of facial muscles by a malfunction of the VII. Cranial nerves (facial nerve) and / or of its motor core.

A hemifacial spasm is usually the result of a nerve compression by a pulsating blood vessel, similar to trigeminal neuralgia.

Hemifacial spasm denotes a one-sided, painless, synchronous contraction of facial muscles by a malfunction of the VII. Cranial nerves (facial nerve) and / or of its motor core. A hemifacial spasm is usually the result of a nerve compression by a pulsating blood vessel, similar to trigeminal neuralgia. Unilateral, involuntary, painless contractions of facial muscles usually start in the eyelid and then spread across cheek and mouth. Contractions may be intermittent at first, but can be almost continuously. The pulsating blood vessel is in MRI often visible, but ultimately the diagnosis of hemifacial spasm is clinical. Partial seizures, blepharospasm and tics cause similar symptoms and should be taken into consideration. The most effective treatment for hemifacial spasm is injection of botulinum toxin (botulinum toxin type A or type B). Treatments for trigeminal neuralgia (z. B. anticonvulsants, baclofen, amitriptyline, surgery) can also be used.
