Abstract

A primeira descrição de dor severa no trajeto do nervo glossofaríngeo foi realizada por Weisenberg, em 1910¹, em um paciente com tumor do ângulo ponto cerebelar. Entretanto, coube a Harris, em 1926², nomear como nevralgia do nervo glossofaríngeo esse raro quadro clínico, caracterizado por paroxismos de dor intensa, unilaterais, na região posterior da língua, no palato mole, na garganta e na região lateral e posterior da faringe, irradiando para o ouvido. A dor pode ser desencadeada por deglutição, tosse, bocejo ou mastigação e normalmente dura de segundos a minutos. A associaç��o de nevralgia do glossofaríngeo e síncope é muito rara e se deve a breves períodos de bradicardia, assistolia ou hipotensão, sendo a primeira descrição dessa associação, com essa fisiopatologia, realizada por Riley e cols., em 1942³.<br>The first description of severe pain in the distribution of the glossopharyngeal nerve is credited to Weisenberg, in 1910¹, in a patient with cerebellopontine angle tumor. However, it was Harris, in 1926², who coined the term glossopharyngeal neuralgia to describe this rare condition characterized by paroxysms of excruciating pain located laterally at the back of the tongue, soft palate, throat, and lateral and posterior pharynx, radiating to the ear. Swallowing, coughing, yawning or chewing may trigger pain, which usually lasts from seconds to minutes. The association between glossopharyngeal neuralgia and syncope is very rare, being identified by brief episodes of bradycardia, asystole, and hypotension. Such an association, with this same pathophysiology, was first described by Riley et al³ in 1942
