Review Case Reports
[A case of combined glossopharyngeal and trigeminal neuralgia].
It is well-known that idiopathic neuralgias of the trigeminal and glossopharyngeal nerves are caused by vascular compression at the root entry zone of the cranial nerves. Because they are functional diseases, initial treatment is medical, especially with carbamazepine. However, if medical therapy fails to adequately manage the pain, microvascular decompression (MVD) is prescribed. ⋯ By virtue of recent progress in imaging technology, minute preoperative evaluations of microvascular compression are possible. Until the 1970's, there might have been some misunderstanding regarding the overlap of symptoms because of lack of the concept of microvascular compression as a cause of neuralgia and rudimentary imaging technology. Minute evaluations of both symptoms and imaging are very important.
