A Case Report of Intraoral Injection of Botulinum Toxin A for Trigeminal Neuralgia: A Rare but Safe Intervention

Abstract

Although off-label, according to the recommendations from guidelines, subcutaneous injections with botulinum toxin A in a follow-the-pain pattern are increasingly being used in trigeminal neuralgia. Subsequently, we report on an elderly woman with trigeminal neuralgia who responded well to intraoral therapy in addition to the subcutaneous injections in the dermal area of the affected trigeminal branch.
