  1. aOne patient had stabbing headache in both the V1 and V2 regions
  2. bV2, V3, lesser occipital nerve, greater occipital nerve, great auricular nerve, and multiple dermatomes. One patient with multiple dermatomes, including V1, were included
  3. c22 out of 28 patients with pain at V1 region and 216 out of 252 patients with pain at other than V1 regions were followed at 2 weeks after initial visit, respectively
  4. ICHD-3 beta: the third beta edition of the International Classification of Headache Disorders. V1: ophthalmic branch of trigeminal nerve; V2: maxillary branch of trigeminal nerve; V3 mandibular branch of trigeminal nerve
