Objective To describe a standardized methodology for the performance of peripheral nerve blocks ( PNB s) in the treatment of headache disorders. Background PNBs have long been employed in the management of headache disorders, but a wide variety of techniques are utilized in literature reports and clinical practice. Methods The A merican H eadache S ociety S pecial I nterest S ection for PNBs and other I nterventional P rocedures convened meetings during 2010‐2011 featuring formal discussions and agreements about the procedural details for occipital and trigeminal PNBs . A subcommittee then generated a narrative review detailing the methodology. Results PNB indications may include select primary headache disorders, secondary headache disorders, and cranial neuralgias. Special procedural considerations may be necessary in certain patient populations, including pregnancy, the elderly, anesthetic allergy, prior vasovagal attacks, an open skull defect, antiplatelet/anticoagulant use, and cosmetic concerns. PNBs described include greater occipital, lesser occipital, supratrochlear, supraorbital, and auriculotemporal injections. Technical success of the PNB should result in cutaneous anesthesia. Targeted clinical outcomes depend on the indication, and include relief of an acute headache attack, terminating a headache cycle, and transitioning out of a medication‐overuse pattern. Reinjection frequency is variable, depending on the indications and agents used, and the addition of corticosteroids may be most appropriate when treating cluster headache. Conclusions These recommendations from the A merican H eadache S ociety S pecial I nterest S ection for PNBs and other I nterventional P rocedures members for PNB methodology in headache disorder treatment are derived from the available literature and expert consensus. With the exception of cluster headache, there is a paucity of evidence, and further research may result in the revision of these recommendations to improve the outcome and safety of these interventions.
