Glossopharyngeal neuralgia is a definite clinical entity. The disease is rare, and the possible clinical variants are not as well understood as they are in cases of trigeminal neuralgia. In its sudden brief painful paroxysms, in the complete relief afforded by section of the posterior root and in the obscure etiology, it resembles tic douloureux of the fifth nerve. The pain of trigeminal neuralgia may originate in any of the peripheral branches of any of the three sensory divisions of the nerve. A priori, it is reasonable to suppose that the same phenomenon may be expected in glossopharyngeal neuralgia, and it does occur. The justification for reporting the following case is the fact that it is an example of paroxysmal neuralgia originating in the tympanic branch of the glossopharyngeal nerve; the trigger zone initiating the pain was probably within the eustachian tube, and complete relief followed intracranial section of the
