How are migraine headaches treated?
The pain management specialist may use a combination of treatment approaches. These include:
- Sphenopalatine ganglion block – This procedure involve inserting a small catheter through the nostril to reach the sphenopalatine ganglion nerves (located at the base of the brain and back of throat). Once the catheter is in place, the doctor injects a long-acting anesthetic onto the nerves, which blocks pain signals. In a study of 22 patients, this procedure offered significant pain relief for patients, which lasted for more than 30 days.
- Medications – The first therapy for migraine headaches is abortive agents, like Maxalt of Imitrex. Preventive medicines include tricyclic antidepressants (nortriptyline and amitriptyline). These drugs affect levels of serotonin and other brain chemicals. In addition, serotonin norepinephrine reuptake inhibitors are used, such as vanlafaxine. Anti-seizure medicines are used also, such as topiramate.
- Occipital nerve block (ONB) – This block is used to relieve pain at the posterior region of the head. A long-acting anesthetic is injected into the scalp near the occipital nerves. Clinical studies show that ONB reduces 50% or more pain intensity and frequency.
- Botox – Botulinum toxin A is used to prevent migraine headaches by paralyzing and blocking acetylcholine release from nerve cells. The injections are given in the forehead and temples, as well as the upper neck region. According to one clinical study, these injections reduced the severity and intensity of migraine pain.
- Radiofrequency denervation – The doctor may use radiofrequency energy to destroy a portion of the nerve root located at the top of the neck (cervical spine). The needle and probe are inserted to the site using x-ray guidance. Based on studies, this procedure is 75% effective.
