64615 Chemodenervation of muscle(s); muscle(s) innervated by facial, trigeminal, cervical spinal and accessory nerves, bilateral (eg, for chronic migraine)

Name of the Procedure:

Chemodenervation of muscle(s); muscle(s) innervated by facial, trigeminal, cervical spinal and accessory nerves, bilateral (e.g., for chronic migraine).

Summary

Chemodenervation is a medical procedure involving the injection of Botox or similar substances into specific muscles. This procedure targets muscles controlled by the facial, trigeminal, cervical spinal, and accessory nerves on both sides of the body, mainly to manage chronic migraines.

Purpose

The primary purpose of this procedure is to alleviate chronic migraines, which are severe, recurrent headaches that significantly impact daily life. By temporarily paralyzing specific muscles, the frequency and severity of migraines can be reduced.

Indications

• Chronic migraines (15 or more headache days per month)
• Severe, refractory headaches not responding to standard treatments
• Conditions causing abnormal muscle contractions or spasms in the facial or cervical regions

Preparation

• Avoid blood-thinning medications like aspirin or ibuprofen for a few days before the procedure, as advised by your healthcare provider.
• Inform your doctor of any allergies, particularly to botulinum toxin or related substances.
• Complete any required diagnostic tests, such as headache diaries or imaging studies.

Procedure Description

1. You will be positioned comfortably, often sitting or lying down.
2. The healthcare provider will clean the injection sites with an antiseptic solution.
3. Using a fine needle, small amounts of botulinum toxin are injected into specific muscles around the forehead, temples, neck, and shoulder regions.
4. Multiple injections may be required, with the exact locations and dosage depending on your symptoms.
5. The procedure typically involves minimal discomfort and does not require sedation or deep anesthesia.

Duration

The procedure usually takes about 15 to 30 minutes.

Setting

The procedure is often performed in an outpatient clinic or a specialized doctor's office.

Personnel

• Neurologist or trained physician
• Registered nurse or medical assistant

Risks and Complications

• Localized pain or bruising at injection sites
• Temporary muscle weakness near the injection areas
• Headache or neck pain shortly after the procedure
• Rare but serious risks include difficulty swallowing, breathing issues, or widespread muscle weakness (if the toxin spreads beyond the target areas)

Benefits

• Reduction in the frequency and severity of migraines
• Improved quality of life and daily functioning
• Potential decrease in the need for migraine medications

Recovery

• Most patients return to normal activities immediately or within a few hours.
• Avoid strenuous activity for 24 hours post-procedure.
• Follow-up appointments may be scheduled to monitor progress and plan future treatments.

Alternatives

• Medications (e.g., oral migraine preventatives, triptans)
• Lifestyle modifications (stress management, dietary changes)
• Physical therapy or acupuncture
• Nerve block procedures
• Each alternative has varying degrees of effectiveness and side effects; discuss these with your healthcare provider.

Patient Experience

• The procedure is usually well-tolerated, with most experiencing minimal discomfort from the injections.
• Any mild pain or swelling typically resolves within a day or two.
• Many patients notice a reduction in migraine frequency within 2 to 4 weeks.
• Pain management strategies can include over-the-counter pain relievers if needed.
