Trigeminal neuralgia poses a significant challenge in clinical management due to its severe and paroxysmal facial pain. This case report discusses the successful management of post-traumatic trigeminal neuropathy in a 70-year-old female who experienced debilitating facial pain following a fall. Despite initial conservative measures, her symptoms persisted, prompting exploration of alternative treatment options. The patient underwent multiple sphenopalatine ganglion blocks, utilizing local anesthetic only, administered transnasally via a cotton-tipped applicator. Significant and sustained relief followed each sphenopalatine ganglion block, leading to a preference for this low-risk option over more invasive interventions like microvascular decompression. This case underscores the potential benefits of sphenopalatine ganglion blocks as an effective, low-risk treatment for refractory post-traumatic trigeminal neuralgia.
