RESUMO
BACKGROUND: Radiofrequency ablation (RFA) has many treatment capabilities, one of which includes long term management of chronic headache. As a result, it has been increasingly used, especially in cases of refractory headache pain. Headaches can be classified as primary and secondary and can result from a variety of serious conditions. Types of primary headaches include tension, migraine, and cluster headaches whereas secondary headaches include headaches because of infection or vascular disease, and cervicogenic headaches. Both types can result in serious debility and diminished quality of life. The treatment of chronic headache pain commonly consists of lifestyle modifications, oral medications, and injectable medications. The aim of this study was to investigate the primary and secondary outcomes of RFA for chronic headache pain. METHODS: A systematic review was conducted using three different databases including PubMed, MEDLINE, and the Cochrane Database. The key concepts of "radiofrequency ablation" and "headache" were used. The search took place in June 2023, and it included articles from the past twenty years. RESULTS: Of the 580 articles found, 32 were included in the review. Most studies focused on pain scores, duration of relief, function, and patient satisfaction. In several studies, RFA was used to target various nerves as the pain generator and compared with modalities such as local anesthetic or corticosteroid. CONCLUSIONS: Overall, RFA shows favorable outcomes in the management of chronic headache pain. Therefore, RFA can serve as an alternative treatment option for patients who fail other conservative treatment regimens. Understanding the outcomes of RFA for headache pain can provide patients and clinicians with evidence for the most appropriate treatment strategies.
