ObjectiveCervicogenic headache has been known to originate from the convergence of the upper 3 cervical and trigeminal afferents. The administration of conservative treatments, interventional procedures, and more recently, pulsed radiofrequency, has been used to relieve cervicogenic headache. In this study, the authors evaluated the clinical efficacy and safety of pulsed radiofrequency targeting the mid-cervical medial branches.Materials And MethodsFrom September 2012 until December 2017, 395 patients were diagnosed with cervicogenic headache based on the third edition of the International Classification of Headache Disorders. The authors treated them conservatively at first, and those patients with nonresolution of pain were treated with mid-cervical medial branches block applied from C3 to C5 twice. Subsequently, if any patient continued to experience persistent pain, the authors classified them as having intractable cervicogenic headache and performed pulsed radiofrequency treatment targeting the mid-cervical medial branches from C3 to C5 bilaterally. The authors analyzed their demographics and used a Visual Analogue Scale to assess their pain for 12 months.ResultsFifty-seven patients were enrolled in this study. The mean age was 49.8 years, and the mean duration of symptoms was 47.7 months. The mean Visual Analogue Scale score was 6.21 before pulsed radiofrequency treatment, and it improved to 1.54 immediately after the procedure without the symptoms recurring for a minimum of 12 months. There were no severe complications, such as vascular or nerve injuries.ConclusionsIn patients with intractable cervicogenic headache, pulsed radiofrequency treatment targeting the mid-cervical medial branches resulted in a satisfactory, long-lasting outcome without serious complications.Copyright © 2021 The Author(s).
