Abstract
In cases which at first sight appear to be a typical glossopharyngeal neuralgia the vagus may be involved as well. In such an event section of the 9th nerve rootlets will not bring relief. Pre-operative diagnosis is facilitated by cocainization of the tonsillar fossa combined with pontocaine block at the jugular foramen. A pure glossopharyngeal neuralgia may be relieved temporarily by cocainization of the tonsillar area. If the vagus nerve is involved, block of the 9th and 10th nerves at the jugular foramen is required to bring temporary relief. This report illustrates the need for accurate knowledge of the intricate anatomy of the cranial nerves for proper diagnosis and treatment of their neuralgias.
