Definition:
Hemifacial spasm (HFS) is a neurological abnormality wherein the blood vessels cause pressure to the cranial nerve due to frequent constrictions. This results to degrees of facial spasming, particularly around the eye.
Diagnosis:
Hemifacial spasms are diagnosed via CT scan.
Treatment:
Botulinum toxin injections are given to patients with the disorder. Surgical treatment meanwhile involves microvascular decompression as well as insertion of teflon strips in between the blood vessels to prevent constrictions.
Symptoms and Signs:
Among the symptoms of hemifacial spasms are redness of the face and pain around the eye and upper cheeks.
Causes:
Hemifacial spasms are caused by the involuntary contraction of the blood vessels that connect the face and the cranial nerves. Due to the pressure, spasms arise.
