Randomized Controlled Trial Multicenter StudyGreater occipital nerve blockade for the treatment of chronic migraine: a randomized, multicenter, double-blind, and placebo-controlled study.
We aimed to assess the efficacy of greater occipital nerve (GON) blockade at chronic migraine (CM) treatment. ⋯ Our results suggest that GON blockade with bupivacaine was superior to placebo and was found to be effective, safe, and cost-effective for the treatment of CM. According to our knowledge, this is the first randomized, multicentre, double-blind, and placebo-controlled study in the literature in this field of work.
