Gasserian ganglion thermal radiofrequency in patients with trigeminal neuralgia
Introduction: Trigeminal neuralgia (TN) affects primarily women over 50 years of age and its etiology is unknown in most cases. Drugs are first line treatment, but they are ineffective in 40% of cases. Interventional therapies are a management option in those cases.
Objective: To determine the safety and efficacy of Gasserian ganglion thermal (TR) radio frequency in patients with TN.
Materials and methods: Descriptive, prospective follow-up study of a cohort of 15 patients with a diagnosis of TN who underwent Gasserian ganglion TR at the Colombian Pain Institute between May 2010 and May 2011, with at least one year follow-up.
Results: The mean age of the patients intervened was 52 years, 73% were females with right-sided predominance (67%) with involvement mainly of the second and third branch of the trigeminal nerve. After the intervention, all 15 patients went from severe pain to a condition rangingbetween mild and no pain, and 50% were even pain-free one year after the procedure.
Conclusions: TN has a significant effect on quality of life. The main treatment is pharmacological but when it fails, Gasserian ganglion TR is an effective and safe option available in our setting.
