Greater Occipital Nerve Block in Management of Acute Migraine Headache

Veronica Hackethal, MD

In the largest study to date of blockade of the greater occipital nerve for migraine treatment, more than half of patients claimed a 50% reduction in pain. 

Blockade of the greater occipital nerve is routinely used to treat acute migraine headache although there is a dearth of conclusive clinical evidence to support the procedure. The current study sought to assess the efficacy of the intervention with a focus in pain relief as the primary outcome. While the study has its limitations, it is a meaningful contribution to the body of evidence in support of a peripheral mechanism underlying migraine etiology.Get a top-line look at the study and its results in the short slide show above.Source: Allen SM, Mookadam F, Cha SS, et al.
