Is Migraine Surgery Ready for Prime Time? The Surgical Team's View

Analyzing Google Search Trends for Migraine Surgery and Nurtec in Response to Public Announcements

Background

Nurtec, a versatile migraine medication, has gained popularity. However, the awareness of migraine surgery remains uncertain.

Methods

Following a descriptive approach, this cross-sectional study used Google Trends data as of December 1, 2023, to analyze internet search patterns. Approval from Vanderbilt University's institutional review board and adherence to Strengthening the Reporting of Observational Studies in Epidemiology guidelines were confirmed. Monthly relative search volume (RSV) data for "migraine surgery," "Nurtec," and "Rimegepant" were collected from January 1, 2004, to November 11, 2023, within the United States. Statistical analysis involved determining mean monthly RSV values and percentage changes for critical periods.

Results

For "Nurtec," a significant surge in RSV occurred from March 2020 to April 2020 (344%). Additional peaks were observed from June 2020 to July 2020 (66%), October 2020 to December 2020 (169%), May 2021 to June 2021 (33%), and May 2023 to June 2023 (14%). "Migraine surgery" exhibited a notable 400% increase in RSV, from March 2005 to May 2005. However, post-2006, RSV for "migraine surgery" consistently remained low without noticeable peaks.

Conclusions

The analysis of RSV trends for "Nurtec" and "migraine surgery" from 2004 to 2023 reveals the impact of pivotal events and marketing strategies on public interest. The distinct peaks in "Nurtec" RSV align with Food & Drug Administration approvals and marketing campaigns, highlighting the medication's accessibility. Conversely, the consistently low RSV for "migraine surgery" indicates limited awareness, emphasizing the need for enhanced promotion and education regarding surgical interventions.

Active Occipital Motion with Digipressure as Preoperative Screening in Migraine Surgery

Background

Modern surgical therapy of chronic headaches/migraines is essentially based on the release/neurolysis of extracranial nerves, which, when compressed or inflamed, act as trigger points and, as such, trigger headache attacks. The aim of this article was to describe a novel maneuver we use as an aid in the preoperative planning of occipital trigger sites.

Methods

In the period of January 2021-September 2023, we operated on 32 patients (11 men, 21 women, age range: 26-68 years), who underwent migraine surgery for occipital trigger point release. All patients were evaluated using the described preoperative maneuver. In a dedicated card, the levels of tenderness at each point were marked accordingly, differentiating them by intensity as nothing (-), mild (+), medium (++), or high (+++). Patients were then operated on at the points corresponding only to the ++ and +++ signs.

Results

At 6-month follow-up, we observed significant improvement (>50%) in 29 patients (91%), with complete recovery in 25 patients (78%).

Conclusions

In our experience, the maneuver described, in addition to being very simple, has been shown to have good sensitivity and reproducibility. We therefore recommend its use, especially for those surgeons beginning their practice in this particular area of plastic surgery.

Comprehensive Criteria for Differential Diagnosis and a Surgical Management Algorithm for Occipital Neuralgia and Migraine Headaches

The differential diagnoses and nuances of the surgical management of occipital migraine and occipital neuralgia have not been clearly discussed in the available literature. This study aims to highlight additional diagnostic features and offers an algorithm for the surgical treatment of occipital migraine and occipital neuralgia based on the vast experience of the senior author spanning over 23 years. A retrospective cohort study was conducted to review the number and distribution of patients who underwent surgical treatment for occipital migraine headaches and neuralgia and the signs and symptoms observed. Among the 660 patients who underwent surgical treatment for headaches within the territory of the greater occipital nerves, 86 patients underwent isolated deactivation of the greater occipital site (site IV) or combined greater and lesser occipital sites (site IV and site VI surgical). Within the isolated occipital headache group, 43 patients met the criteria for migraine headaches and 43 for occipital neuralgia. Our additional observation on the differences between the occipital neuralgia and migraine groups included that occipital neuralgia is more commonly unilateral, less commonly familial, and more commonly associated with a whiplash-type injury. In addition, the patient with occipital neuralgia can consistently identify the distinct point of pain using the index finger. An ultrasound Doppler signal can also be detected at the pain site and a pulse is often palpable in the site identified by the patient. Occipital neuralgia is also commonly continuous and unrelenting, with occasional spikes of shooting pain, and is less likely to respond to botulinum toxin-A injection. Patients with occipital neuralgia often have a single-site headache while patients with migraine headaches often suffer from headaches in multiple sites. Additional clinical criteria are offered for the differential diagnosis of occipital migraine headaches and occipital neuralgia based on the vast experience of the senior author and the developed surgical management algorithm.

Current Evidence in Migraine Surgery: A Systematic Review

INTRODUCTION

Migraine headache is a widespread neurovascular disorder with an enormous social and economic impact. A subgroup of patients cannot be managed with pharmacological therapy. Although surgical decompression of extracranial sensory nerves has been proposed as a valid alternative treatment option, the medical community remains reluctant to accept it.

MATERIALS AND METHODS

This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. An electronic search was performed in September 2020 on PubMed, ScienceDirect, CENTRAL, and Google Scholar databases for original articles reporting outcomes on migraine surgery.

RESULTS

The search strategy revealed a total of 922 studies, of which 52 were included in the review. Significant improvement was reported in 58.3% to 100% and complete elimination in 8.3% to 86.8% of patients across studies. No major complications were reported.

DISCUSSION

This systematic review demonstrates that migraine surgery is an effective and safe procedure, with a positive impact in patients' quality of life and a reduction in long-term costs.

CONCLUSION

There is considerable scientific evidence suggesting extracranial migraine surgery is an effective and safe procedure. This surgery should be considered in properly selected migraineurs refractory to medical treatment.

A Comprehensive Review of Surgical Treatment of Migraine Surgery Safety and Efficacy

BACKGROUND

Recent clinical experience with migraine surgery has demonstrated both the safety and the efficacy of operative decompression of the peripheral nerves in the face, head, and neck for the alleviation of migraine symptoms. Because of the perceived novelty of these procedures, and the paranoia surrounding a theoretical loss of clinical territory, neurologists have condemned the field of migraine surgery. The Patient Safety Subcommittee of the American Society of Plastic Surgeons ventured to investigate the published safety track record of migraine surgery in the existing body of literature.

METHODS

A comprehensive review of the relevant published literature was performed. The relevant databases and literature libraries were reviewed from the date of their inception through early 2018. These articles were reviewed and their findings analyzed.

RESULTS

Thirty-nine published articles were found that demonstrated a substantial, extensively replicated body of data that demonstrate a significant reduction in migraine headache symptoms and frequency (even complete elimination of headache pain) following trigger-site surgery.

CONCLUSIONS

Migraine surgery is a valid method of treatment for migraine sufferers when performed by experienced plastic surgeons following a methodical protocol. These operations are associated with a high level of safety. The safety and efficacy of migraine surgery should be recognized by plastic surgeons, insurance companies, and the neurology societies.
