Multiple Cranial Nerve Blocks in Patients With Chronic Headache


Multiple cranial nerve blocks may provide an efficacious, well tolerated and reproducible transitional treatment for chronic headache disorders, a new study found. The uncontrolled, open-label study included 119 patients with chronic cluster headache, chronic migraine, short-lasting unilateral neuralgiform attack disorders, new daily persistent headaches, hemicrania continua and chronic paroxysmal hemicrania. All had failed to respond to greater occipital nerve blocks. Researchers found:

  • Response rate for the entire cohort was 55.4%: Chronic cluster headache (69.2%), chronic migraine (49%), short-lasting unilateral neuralgiform attack disorders (56.3%), new daily persistent headache (10%), hemicrania continua (83.3%), and chronic paroxysmal hemicrania (25%).
  • Time to benefit was between 0.5 and 33.58 hours.
  • Benefit was maintained up to 4 weeks in over half of responders in all groups except chronic migraine and paroxysmal hemicrania.
