Hemifacial spasm is a rare disorder that is caused by a blood vessel cross-compressing the facial nerve near the nerve's entry into the brain stem. Electrical stimulation of one branch of the facial nerve on the affected side in patients elicits a response from muscles that are innervated by another branch. and it may thus be a result of 痙攣（けいれん）とは、筋肉が急激に不随意（自分の意志とは関係なく）に収縮する発作のことをいい、全身または一部の筋肉に起こります。. 骨格筋（四肢の筋）に発作的にみられる急激な収縮（てんかん性の痙攣、convulsion）は救急治療の対象となり Hemifacial spasm (HFS) is characterized by paroxysmal, involuntary twitching of facial muscles on one side of the face innervated by the ipsilateral facial nerve (seventh cranial nerve). The abnormal involuntary firing of the peripheral facial nerve triggers short or longer contractions of muscles of facial expression. HFS is considered a subtype of peripheral (neuromuscular) movement disorder Abstract In two patients with hemifacial spasm These observations are consistent with the hypothesis that there is ephaptic transmission among peripheral branches of the facial nerve at the site of compression in HFS.
