Randomized Controlled TrialThe efficacy of greater occipital nerve blockade in chronic migraine: A placebo-controlled study.
GON blockade with local anesthetics is an effective treatment for a group of headaches, such as cervicogenic headache, cluster headache, occipital neuralgia, migraine. Our aim was to evaluate the efficacy of greater occipital nerve (GON) blockade in patients with chronic migraine (CM) by using a control group. ⋯ Our results suggest that GON blockade with bupivacaine was superior to placebo, has long-lasting effect than placebo, and was found to be effective for the treatment of CM. More studies are needed to better define the safety and cost-effectiveness of GON blockade in CM.
