Background and Aims:

Migraine is a primary headache disease which significantly impairs quality of life. As the drugs used in the treatment of migraine cannot provide full recovery and there are serious side effects, there is an increased need for alternative treatment methods. When migraine headache is refractory to conservative measures, a number of interventional treatment options exist, including: local occipital nerve anesthetic and corticosteroid infiltration, botulinum toxin A injection, occipital nerve subcutaneous neurostimulation, and occipital nerve PRFA. The aim of this study was to evaluate the efficacy of PRFA and local anesthesia on bilateral GON block in the treatment of migraine patients. 

Methods:

ASAI-II and aged between 15-64 years old 42 patients who had migraine were included in the study. Study groups were local anesthesia (Group L), radiofrequency ( Group RF) on greater occipital nerve. Group L (1.5 ml 2%lidocaine) and Group RF (50 HZ, 0.3V) had been performed using landmarks (2 cm lateral and 2 cm inferior of the external occipital protubarence). The patients were evaluated in respect of VAS scores, attack frequency and attack duration (hour). These parameters were evaluated before, 1week, 1month and 3months after the procedures .

Results:

 

Conclusions:

Although bilateral PRFA and local anesthesia of GON block is a safe, simple and effective treatment methods for migraine headache PRFA reduced attack frequency significantly and also had significantly less analgesic need at the 3rd month. More researches are needed to support the use of PRFA for migraine.
