This study investigated the effectiveness of three treatment interventions for managing migraine symptoms over a three-month assessment period: single greater occipital nerve block (GON), repetitive GON block, and single GON block combined with onabotulinium toxin A (BoNT-A) treatment. Significant improvements were observed across all treatment groups in various migraine-related parameters, including medication usage, frequency and severity of attacks, and subjective measures such as Headache Impact Test-6 scores and Pittsburgh Sleep Quality Index scores. Notably, all groups showed reductions in NSAID and triptan usage, total number of attacks with VAS>4, and number of headache days. However, slight differences in the magnitude of improvements were observed between the groups, with GON block combined with BoNT-A treatment demonstrating slightly greater reductions compared to single GON block treatment. Additionally, the integration of BoNT-A therapy alongside GON blockade appeared to confer supplementary benefits in migraine prophylaxis. These findings highlight the importance of implementing comprehensive treatment approaches to address various aspects of migraine management and improve patient outcomes.

The aim of this study was to compare the effectiveness of greater occipital nerve (GON) block and pulsed radiofrequency (PRF) treatment in chronic migraine patients. Seventy patients admitted to the Neurology and Algology outpatient clinic between September 2023 and December 2023 and diagnosed with chronic migraine according to The International Classification of Headache Disorders 3rd Edition (ICHD-3) criteria were included in the study. Patients were randomized into 2 groups to receive ultrasound-guided repeated GON block and PRF.

Background: Chronic cluster headache (CCH) is an excruciatingly painful condition that can be difficult to treat sufficiently with the available medical treatment options. The greater occipital nerves (GON) are of major interest in treating CCH, and various invasive treatment modalities, such as stimulating or blocking the nerves, have been applied. Because the terminal segment of the GON has a superficial course, the nerve is also accessible for non-invasive transcutaneous stimulation.

Dupilumab, a fully human monoclonal antibody, blocks interleukins 4 and 13, key and central drivers of type 2 inflammation. Dupilumab has been effective in the treatment of certain types of moderate-to-severe asthma across several clinical trials.

Background: This manuscript presents the challenges of treating various forms of headaches and the potential of interventional techniques targeting the greater occipital nerve (GON) to alleviate the burden on patients. Occipital neuralgia, characterized by stabbing or shooting pain in the base of the skull, is often associated with primary, cervicogenic, or migraine headaches. While occipital nerve blocks offer temporary relief, durable treatment options are limited.

Article Synopsis
- A meta-analysis was conducted to evaluate the effectiveness of greater occipital nerve (GON) block in reducing pain for those suffering from acute migraines.
- The analysis included four randomized controlled trials with a total of 224 patients, showing that GON block significantly reduced pain scores at 30 and 45 to 60 minutes post-intervention, but not at the earliest 0 to 15 minutes.
- While GON block can help decrease pain intensity for acute migraine sufferers, it did not have a significant effect on sustained headache relief or the need for rescue medication.
