舌咽神経痛3症例—頸部における舌咽神経の切断について

GLOSSOPHARYNGEAL NEURALGIA WITH A BRIEF CONSIDERATION ON GLOSSOPHARYNGEAL NEUROTOMY THROUGH CERVICAL APPROACH: A REPORT OF THREE CASES

　Ⅰ．緒言

　最近3年間にわれわれは3例の舌咽神経痛を経験した。その中の2例については茎状突起切断術と頸部よりする舌咽神経切断術を行なつて神経痛は治癒したが，その1例では術後嚥下障害を来たし，一侍重篤な状態におち入つたのでその臨床経過に若干の考察を加えて報告する。

　Three cases of glossopharyngeal neuralgia are reported. The two of these cases were treated by glossopharyngeal neurotomy through cervical approach and the complaint in both cases was completely abated. However, in one a post-operative complication developed with difficult swallowing due to paralysis of the soft palate and other portions of the pharyngeal muscles.

　The authors reviewed a number of literatures with discussions on the effects of glossopharyngeal neurotomy on swallowing. It was the consensus of opinion that glossopharyngeal neurotomy alone will not cause swallowing difficulties but it should most likely be relagated to some injury to the pharyngeal portion of the vagus nerve.
