Glossopharyngeal neuralgia of traumatic origin.

Glossopharyngeal neuralgia of traumatic origin is very rare. Two interesting cases are presented, one with a skull fracture involving the jugular foramen and the other associated with an operation for an acoustic tumor. Carbamazepine gave good results and both patients improved within 24 hours. The glossopharyngeal and vagal nerves might have been injured in the region of the root entry zone giving rise to the neuralgia. Pertinent literature is briefly discussed.
