Glossopharyngeal neuralgia associated with cardiac syncope.

Glossopharyngeal neuralgia is an uncommon condition that has rarely been described in association with syncope. We report here 2 cases of glossopharyngeal neuralgia in elderly patients. Both were male and underwent temporary pacemaker insertion to prevent syncopal episodes. We discuss the clinical and surgical treatment of glossopharyngeal neuralgia, the role of cardiac stimulation, and the possible physiopathological mechanism of the associated cardiac disturbances.
