Background and Purpose: Hemifacial spasm HFS is a rare neuromuscular disorder characterized by unilateral, involuntary, and paroxysmal contractions of orofacial muscles. Methods: Thirty patients with HFS and 30 age- and sex-matched healthy participants consented to the study. Cortical gray matter thickness was assessed, and subcortical volumetric analysis was performed. Post hoc correlations with HFS severity and measures of mood i. Results: There were no significant differences in cortical thickness in HFS patients compared to healthy controls.

Our leading neuroscience team offer treatment for hemifacial spasm, including microvascular decompression surgery. This is a rare condition characterised by irregular, involuntary muscle contractions spasms on one side of the face. The cause is not known but one theory is that an artery presses against the facial nerve the nerve that moves the face , irritating the nerve and causing the twitching. These involuntary spasms can occur around the eye, cheek and mouth, and can get worse under stress. General symptoms include:. Your consultant will discuss your treatment options and help to determine the best approach for you.
Hemifacial spasm is usually diagnosed by inspection which mainly identifies involuntary movements of orbicularis oculi. Assessing abnormal muscle responses AMR is another diagnostic method. We report a case of left hemifacial spasm without detectable involuntary facial movements.
Hemifacial spasm is a nervous system disorder in which the muscles on one side of your face twitch involuntarily. Hemifacial spasm is most often caused by a blood vessel touching a facial nerve, but it may be caused by a facial nerve injury or a tumor, or it may not have a cause. Hemifacial spasm is most often caused by a blood vessel touching a facial nerve.
