Trigeminal neuralgia (TN) is a neuropathic pain syndrome characterized by severe unilateral paroxysmal facial pain. Pain attacks are usually stimulated by tactile irritation within the region of the trigeminal nerve.Trigeminal neuralgia pain typically remits and relapses, even when patients are on conventionally used treatments, resulting in a major source of disability and poor quality of life. Multiple forms of treatment are available for its management, but it is often resistant to conventional treatments. Radiofrequency (RF) ablation is one of the best treatment modalities to relieve pain in TN but even after successful RF ablation of Gasserian ganglion, there may be relapses. Rarely, patient may present with pain in other distributions of trigeminal nerve. We report a case of a 55-year-old female having relapsing form of TN, switching from V2 to V3 division of trigeminal nerve distribution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
