[The pathogeny and treatment of glossopharyngeal neuralgia].
OBJECTIVE
To investigate the etiopathogensis of glossopharyngeal neuralgia, and to research the curative effect of medicine and operation on it.


METHODS
The microsurgical relationships between glossopharyngeal nerve and the posterior inferior cerebellar artery were examined in 30 adults cadavers. Twenty patients with glossopharyngeal neuralgia were treated by operation in which the glossopharyngeal nerves were observed and sectioned.


RESULTS
10 out of the glossopharyngeal nerves in 30 adults cadavers were observed contacting with the posterior inferior arteries which represented 16.67 percent of all the cases. 8 of 20 patients were observed that their glossopharyngeal nerve were compressed and distorted by the posterior inferior cerebellar arteries. They were cured by operations.


CONCLUSIONS
Vascular compression may be one of the causes of glossopharyngeal neuralgia, but not the only one. The curative effect of section of glossopharyngeal nerve is sure. This paper pointed out that this kind of operation should be a choice.
