Headache disorders are typically managed medically, but Mayo Clinic plastic surgeons treat a subset of patients with refractory, anatomically mediated headaches secondary to peripheral nerve compression. This approach is commonly referred to as nerve decompression surgery for migraines. It involves decompression of the supraorbital and occipital nerves to reduce or alleviate trigger point headaches and associated migraine-like symptoms.

"Unlike primary migraine disorders, trigger point headaches are caused by a structural problem and not a physiological issue," says Antonio J. Forte, M.D., Ph.D., a plastic surgeon at Mayo Clinic in Jacksonville, Florida. "When symptoms are driven by a structural compression, medical therapy alone is often insufficient, and surgical decompression may be required."

Peripheral nerve compression as a headache generator

Compression of peripheral sensory nerves in the occipital and frontal regions of the head by muscle, fascia or osseous structures results in neuralgia. Similar to other entrapment neuropathies, such as carpal tunnel syndrome, the nerve compression generates symptoms that progressively worsen if left untreated. Nerve irritation may manifest as migraine-like headaches when the occipital or supraorbital nerve — the most common headache trigger sites — is involved:

• Greater occipital nerve compression, the most prevalent trigger site, is marked by pain in the posterior neck that radiates through the lateral scalp.
• Supraorbital nerve compression is characterized by pain originating near the eyebrow and radiating into the forehead.

However, because supraorbital and occipital nerve compression can cause migraine-like symptoms, many people refer to trigger point or nerve compression headaches as migraines and seek treatment accordingly. While the etiologies of trigger site and migraine headaches may overlap, peripheral nerve compression represents a distinct and potentially treatable diagnosis.

In some patients, trigger point headaches may contribute to the multifactorial etiology of a migraine disorder, underscoring the importance of careful evaluation.

Coordinated approach to diagnosing supraorbital and occipital neuralgia

Diagnosing peripheral nerve compression can be challenging and requires a methodical, multidisciplinary approach. Diagnosis typically relies on:

• Recognition of consistent and reproducible pain patterns.
• Response to targeted diagnostic interventions.
• Exclusion of alternative etiologies.

At Mayo Clinic, neurologists first rule out intracranial pathology and initiate first line therapies, including pharmacological management and botulinum toxin injections. For patients with refractory symptoms despite medications and Botox, physical medicine and rehabilitation specialists administer diagnostic and therapeutic nerve blocks. Temporary symptom relief supports the diagnosis and helps identify the involved nerve.

"Nerve compression headaches start the same way every time," Dr. Forte says. "Pain near the brow or in the back of the neck that radiates in a specific pattern. We collect clues like this that indicate we're not dealing with a regular headache or migraine. But multifactorial headache etiology is common and can make diagnosis complex."

Dr. Forte stresses that patients must be counseled regarding the possibility of having concomitant headache disorders. However, if supraorbital or greater occipital nerve compression is diagnosed, surgery may substantially reduce symptoms by addressing a predominant factor.

Targeting peripheral nerve compression with surgery

Awareness of nerve decompression surgery for headaches remains limited. Dr. Forte notes that many of the patients he treats surgically have been living with headache pain every day for years. "When a patient has headaches that are secondary to nerve compression, this surgery can provide meaningful improvement in the frequency and severity of the headaches," Dr. Forte explains.

Releasing the supraorbital or greater occipital nerve can provide immediate symptom relief.

"There is no guarantee that the surgery will provide full relief because headaches of a different etiology may still exist after surgery," Dr. Forte says. "In appropriately selected patients, studies and institutional experience suggest meaningful improvement in frequency and severity — often in the 80% range."

Greater occipital and supraorbital nerve decompression surgeries both use anatomically guided exploration to remove the compressive elements:

• Greater occipital nerve decompression surgery is performed through a 5 cm incision between the posterior hairline and occiput.
• Supraorbital nerve decompression surgery is approached through an upper eyelid incision.

Once the nerve is located, a path is cleared around the nerve for release. Intraoperatively, compressed nerves often appear enlarged, discolored and irritated. Decompression restores space around the nerve, facilitating recovery and regeneration.

Recovery is typically straightforward, with minimal postoperative restrictions. Incision scars are concealed within the hairline or eyelid crease. Patients report enhanced quality of life, improved daily function and decreased reliance on emergency department care.

Importance of peripheral nerve compression recognition and timely referral

While the majority of headache disorders are not surgically treatable, peripheral nerve compression represents a distinct and potentially life-altering etiology. Increased awareness among referring physicians is essential to ensure timely referral and diagnosis, which can significantly alter patient outcomes.

Referral for surgical evaluation should be considered when:

• Headaches consistently originate from a focal trigger site.
• Symptoms are refractory to standard therapies.

For patients with focal, reproducible headaches that fail standard therapy, early referral for diagnostic nerve blocks can identify those who may benefit from surgical decompression. "More than 90% of people, including physicians, do not know that this treatment option exists," Dr. Forte says. "If the first line of treatment is unsuccessful, an early referral provides the patient with this potentially life-changing option."

Patients with patterns not consistent with peripheral compression migraines include:

• Diffuse, nonlocalized headache patterns.
• No response to diagnostic nerve blocks.
• Predominant central migraine features without trigger site.
