Glossopharyngeal Neuralgia
摘要
Glossopharyngeal neuralgia (GPN), is a painful cranial nerve disorder with an estimated annual incidence of 0.2–0.7 per 100,000 [1, 2]. Although rare, GPN is a most debilitating condition due to lancinating and severe paroxysms of pain in the sensory afferents of the pharyngeal and auricular branches of the glossopharyngeal and vagus nerves (CN IX and X) [3–5]. The term vagoglossopharyngeal neuralgia has been used to describe paroxysmal pain attacks, primarily involving the palantine tonsil and posterior area of tongue, accompanied by “vagal” symptoms (e.g., syncope, bradycardia, and asystole).
