Hemifacial spasm is a neurological disorder that leads to involuntary contractions of the facial muscles, commonly affecting one side of the face. At Atlas Institute in Los Angeles, under the guidance of Dr. Aaron Cohen-Gadol, a board-certified neurosurgeon and founder of the innovative Atlas Institute of Brain & Spine, we offer specialized care for this condition, addressing both the symptoms and the underlying causes. With over 7,500 complex surgeries performed, Dr. Cohen-Gadol is known worldwide for his expertise in managing cranial nerve disorders and has influenced over 100,000 patient lives globally.
Dr. Cohen gave me my life back. It’s cliché, but the truest explanation of the amazing work he and his entire team did for me. He performed a very tricky Microvascular decompression of my glossopharyngeal nerve. I have had zero symptoms since surgery!
I am convinced Dr. Cohen is the best of the best, and feel so grateful and lucky to have been and continue to be able to call him my doctor. Someone at this high of a level who remains so friendly and compassionate is not common. You cannot be in better hands than Dr. Cohen and his team. Forever grateful.
How Hemifacial Spasm Affects Daily Life
Patients experiencing hemifacial spasm may notice persistent twitching, beginning near the eye and potentially extending to other facial muscles, including those around the cheek and mouth. This condition can be particularly challenging, leading to visual disturbances that may complicate activities like reading or driving. While hemifacial spasms are not typically painful, they can induce significant social anxiety and affect overall quality of life. Approximately 10% of hemifacial spasm cases resolve on their own without treatment, although the reasons for this spontaneous improvement are not well understood, making professional evaluation essential.
Identifying Signs of Hemifacial Spasm
Common symptoms of hemifacial spasm include:
- Involuntary twitching on one side of the face, especially near the eye
- Muscle spasms affecting the areas around the cheek and mouth
- Twitching that may occur even during sleep
- A “ticking” sound from the ear due to muscle contractions in the middle ear
These symptoms can worsen under stress or when talking, prompting many individuals to seek a diagnosis and treatment options.


What Causes Hemifacial Spasm to Occur?
Hemifacial spasms primarily stem from compression of the facial nerve at the brainstem, often due to nearby blood vessels or tumors. Other contributing factors can include:
- Facial nerve injury
- Previous episodes of Bell’s palsy
- Neurological disorders
In some cases, the exact cause remains unknown, which can make diagnosis challenging. Microvascular decompression (MVD) surgery is one of the most effective treatments for hemifacial spasm, as it aims to relieve pressure on the facial nerve, potentially offering a long-term solution for patients.
Surgical and Non-Surgical Treatments for Hemifacial Spasm
Treatment options for hemifacial spasm range from medical management to surgical interventions:
- Medical Management: Medications like carbamazepine, clonazepam, or botulinum toxin (Botox) injections may provide temporary relief from spasms but do not address the underlying cause. Botulinum toxin injections are the most common treatment for hemifacial spasm, effectively controlling symptoms in most individuals.
- Microvascular Decompression Surgery: This surgical technique aims to relieve pressure on the facial nerve, offering lasting relief for many patients. Given Dr. Cohen-Gadol’s extensive experience and his pioneering work in neurosurgery, patients can trust in the quality of care provided.
Exploring Diagnostic Methods for Hemifacial Spasm
Diagnosis of hemifacial spasm typically involves a detailed neurological examination and medical history. Although no single test can confirm the condition definitively, advanced imaging techniques such as MRI may help identify anatomical issues like nerve compression, which could contribute to the symptoms.
