Introduction:
Occipital nerve stimulation (ONS) is an emerging and promising preventive treatment for refractory chronic migraine.
Aim:
To evaluate the mechanisms of actions, clinical studies, implantation techniques and inclusion criteria of the ONS as a preventive treatment for migraine.
Development:
This work includes a non-systematic review of the literature on the above-mentioned aspects of ONS as a treatment for refractory chronic migraine. This disease affects approximately 2% of the population and results in a significant impairment in quality of life, economic burden and interference with labor and social activities. ONS is an emerging and promising therapy for the treatment of chronic migraine with greater than 50% pain reduction in most of open-label studies and published clinical trials. Although the mechanisms of action remain unknown, there seem to be a neuromodulation of the transmitted nociceptive trigeminal information in the trigeminal caudal nucleus, what could be explained by means of the Melzack and Wall pain gate theory. ONS is a safe and well tolerated treatment, and its most frequent side effects are usually local such as electrodes displacement or infections of the surgical incision. These complications do not usually require the electrodes withdrawal.
Conclusions:
ONS is an effective, well tolerated and safe treatment for the prevention of chronic migraine and could emerge as a useful option for those patients with medically refractory chronic migraine.
Insights
Occipital nerve stimulation (ONS) offers a promising preventive treatment for chronic migraine. This therapy is safe, well-tolerated, and effective in reducing pain for many patients.
Area of Science:
- Neuromodulation
- Neurosurgery
- Pain Management
Background:
- Chronic migraine affects 2% of the population, causing significant disability.
- Refractory chronic migraine lacks effective preventive treatments.
- Occipital nerve stimulation (ONS) is an emerging therapy for this condition.
Purpose of the Study:
- To review ONS mechanisms, clinical studies, and implantation techniques for migraine prevention.
- To evaluate ONS as a treatment for refractory chronic migraine.
- To assess ONS inclusion criteria and efficacy.
Main Methods:
- Non-systematic literature review on ONS for refractory chronic migraine.
- Analysis of clinical studies, implantation techniques, and patient selection.
- Evaluation of safety and tolerability data.
Main Results:
- ONS demonstrates >50% pain reduction in most open-label studies and clinical trials.
- Mechanisms may involve neuromodulation of trigeminal nociceptive pathways.
- ONS is safe and well-tolerated, with common side effects being local.
Conclusions:
- Occipital nerve stimulation is an effective, safe, and well-tolerated preventive treatment for chronic migraine.
- ONS can be a valuable option for patients with medically refractory chronic migraine.
- Further research into ONS mechanisms is warranted.
