Hemifacial Spasm
Hemifacial spasm is a condition that causes involuntary twitching or spasms on one side of the face, most often starting around the eye before sometimes spreading to other facial muscles.
Signs & Symptoms
Intermittent, involuntary twitching or spasms on one side of the face that can worsen with stress or fatigue over time.
Causes & Risk Factors
Hemifacial spasm is most often caused by a blood vessel pressing on the facial nerve near the brainstem. Less commonly, it can result from a nearby tumor or nerve injury.
Diagnosis
Diagnosis is based on the characteristic pattern of symptoms, a neurological exam, and MRI imaging to look for a cause, such as a blood vessel or mass pressing on the nerve.
Treatment Options
Treatment may include medication or botulinum toxin (Botox) injections to reduce spasms. For symptoms that don’t respond well, surgery to relieve pressure on the facial nerve may be considered.
