The Efficacy and Safety of Sphenopalatine Ganglion Pulsed Radiofrequency Treatment for Chronic Cluster Headache

Overview

Cluster headache (CH) is a devastating disorder characterized by ipsilateral headache and associated trigeminal autonomic symptoms, with a yearly prevalence of 0.1%. There is a huge clinically unmet demand for an effective therapeutic method for CH. Previous evidences indicate that pulse radiofrequency (PRF) targeting the sphenopalatine ganglion (SPG) is a safe, minimally invasive, effective treatment for CH. This randomized, controlled trial aimed to establish the safety and efficacy of SPG PRF for patients with chronic CH.

Interventions

  • Procedure PRF
    After the puncture needle reached the sphenopalatine ganglion (SPG), patients in the PRF group received PRF treatment in automatic mode for 360 s, at a maximum of 42°C, pulse frequency of 2 Hz, and pulse width of 20 ms.
  • Procedure NB
    After the puncture needle reached the sphenopalatine ganglion (SPG), patients in the NB group received nerve block with a mixture of 40 mg of triamcinolone and 2 ml of 0.75% bupivacaine with 2 ml of normal saline and 1:100000 epinephrine.

Primary outcome measures

  • The mean attack frequency in the last 4 weeks (week 8-12) after procedure [Time frame: In the last 4 weeks (week 8-12) after procedure]
Secondary outcome measures (7)
  • Mean attack frequency [Time frame: From baseline to each 4-week interval through 1 year after procedure]
  • 50% reduction of mean attack frequency [Time frame: From baseline to each 4-week interval through 1 year after procedure]
  • 30% reduction of mean attack frequency [Time frame: From baseline to each 4-week interval through 1 year after procedure]
  • Patient Global Impression of Improvement [Time frame: At month 1, month 2, month 3, month 6, and month 12 after procedure]
  • Mean attack intensity [Time frame: From baseline to each 4-week interval through 1 year after procedure]
  • Patient satisfaction scores [Time frame: At month 1, month 2, month 3, month 6, and month 12 after procedure]
  • The incidence of perioperative adverse events [Time frame: Across 1 year after procedure]
