There is a clear interest among chronic migraine patients in learning about treatments that do not involve lots of medications. To this effect, some of the most talked-about alternative therapies include:
- Supraorbital nerve decompression surgery
- Botox injection treaments
- Transcranial magnetic stimulation (TMS)
How Radio Frequency Ablation (RFA) Can Keep Migraines under ControlIn a way, RFA is similar to supraorbital nerve decompression surgery in the sense that it provides migraine relief by means of direct intervention on nerve clusters believed to cause headaches. This is a slightly invasive procedure; it calls for the insertion of a probe similar to a needle, and it is often applied to the neck area. The nerves that RFA typically intervenes are located near the C1-C5 vertebrae.
The RFA probe uses radio waves to create an electric current, which in turn heats up the nerve endings and essentially incapacitate them. To this effect, RFA is also similar to nerve block applications; in fact, pain specialists frequently apply blocks to determine if their patients are good candidates for RFA.
Effectiveness and Risks
RFA is a mid-term therapeutic solution for migraine patients whose headaches are thought to originate from their necks. The nerves are not permanently disabled; they tend to regenerate after a while. Three quarters of patients who undergo RFA report complete relief that lasts about a year. At this point, RFA is second to supraorbital nerve decompression, also known as migraine surgery, in terms of relief.
Not all chronic migraine patients will benefit from RFA; even those who respond positively to nerve block applications are not guaranteed to experience comprehensive relief. There is little risk involved in the procedure itself since it is minimally invasive, but some patients can expect discomfort, edema and the possibility of infection. All of these complications can be prevented and remedied.
Very few patients have reported that their migraine conditions have actually worsened after receiving an RFA procedure. This may be explained by the fact that the nerve centers in the cervical area are not the only ones active during the headache phase of a migraine attack. Migraine surgery may be a better option for these patients since many cranial, cervical and facial nerves can be intervened.
