Percutaneous Radiofrequency Thermocoagulation via Hartel Technique for the Treatment of Trigeminal Neuralgia: A Systematic Review

Objective: Percutaneous radiofrequency thermocoagulation of the gasserian ganglion via Hartel technique is an accepted alternative to the treatment of trigeminal neuralgia in a selected group of patients. We investigated all the possible outcomes associated with the procedure in a systematic review.

Methods: A systematic research using the PRISMA statement recommendations including PubMed, Cochrane library, EMBASE, EbscoHost and Mediclatina databases searching for prospective studies analyzing the outcomes following the percutaneous radiofrequency thermocoagulation of the gasserian ganglion via Hartel technique was developed.

Results: Thirteen studies met the inclusion criteria and 1,896 patients were included in the analysis. This technique was associated with favorable outcomes in terms of safety, efficacy, patients’ satisfaction and quality of life measures. There is no consensus regarding stimulation parameters during the procedures. With higher temperatures, higher procedure duration and continuous radiofrequency the rate of complications associated with the procedure increase.

Conclusion: Percutaneous radiofrequency thermocoagulation of the gasserian ganglion via Hartel technique is an excellent method for the treatment of trigeminal neuralgia without response to pharmacological treatment in a selected group of patients.
