Occipital nerve block (ONB) is an effective procedure for treating occipital headache pain. However, traditional sub-occipital approaches to ONB remain underutilized in the acute and chronic settings. An alternative location for ONB is the superior nuchal line, where anatomic studies show a reliable relationship between occipital artery and greater occipital nerve. This study evaluated the efficacy and validity of an alternative, single skin insertion, paresthesia-based approach to block both the greater and lesser occipital nerve.
