The advent of anti-CGRP medications is an example of translational research made real. Pioneering research by Drs. Lars Edvinsson and Peter Goadsby has yielded the monoclonal antibody therapeutics and will likely also result in the gepants. ⋯ They work in patients who have already had lack of success with at least 2-4 previous preventive medications. Pent-up demand for designer, well-tolerated, and effective migraine preventive medication in the USA has resulted in more than 100,000 individual patients prescribed erenumab from May to December of 2018, and the numbers continue to increase. The preventive treatment of migraine in the USA has shifted dramatically, and is likely to do so in the rest of the world as well.

Migraine is a common, severe disease, affecting the brain and blood vessels, causing much pain, time missed from work and family, and severe disability. It affects approximately 12% of most Western populations studied and affects women three times more than men. ⋯ It affects less than 0.1% of the population and is slightly more prevalent in men than women. Although we have some acute care and preventive medications for both types of headache, no treatment is optimal for each patient and some will not respond well or have significant adverse events to existing therapies.

Among cephalgias, cluster headache (CH) is the rarest and the most disabling, explaining the appellation of "suicide headache." Up to 20% of chronic CH reveals to be resistant to pharmacological treatments, in which case interventional procedures should be considered. Many reports evaluated invasive approaches and a wide strand of research is dedicated to the sphenopalatine ganglion. Our paper will now be focused on providing an overview on modern applications on the sphenopalatine ganglion (SPG), their outcomes, and their feasibility in terms of risks and benefits. ⋯ First results seem promising and considering the low frequency of side effects or complications, we should think of expanding the indications of the procedures also to those conditions. Outcomes certainly suggest that further studies are necessary in order to understand which method is the most effective and with less side effects. Placebo-controlled studies would be pivotal, and tight collaboration between neurologists and otorhinolaryngologists should also be central in order to give correct indications, which allow us to expect procedures on the SPG to be an effective and mostly safe method to control either refractory ECH or CCH.
