高度なる顎関節強直症手術例

　戦後化学療法の発達及び医療知識の晋及は我が臨床の様相をも一変せしめ，新なる分野の開拓が是非必要となつて来た。特に境界域疾患に対する治療の拡大は先づ晋及さる可き当面の問題と思われる。茲に報告せんとする顎関節強直は耳鼻科疾患とも密接な関連性を有し，耳鳴の発現にも関係し，新な関心を呼ぶ疾患である。従来如何なる関係からか我が境域では殆んど対称とされていなかつた感があるので，本治験例を報告して，この方面進出えの御参考と致したい。

SHIBATA reports a case of ankylosis of man-dibular joint that developed gradually as a sequ-eala to typhoid fever complicated at the time with an attack of otitis media of the left side. The patient, a man aged 26, had at a slight di-fficulty in opening his mouth, a condition which gradually worsened to a state where he no lon-ger was able to open at all.

The left mandibular joint showed, when expo-sed by surgical intervention, a firm ankylosis by trophic bony changes ; the three important stru-ctures of the articulation the tuberculum articu-lare, auditory process and the condyle firmly adherent to each other. Unlike cases that are found with ankylosis less severe in degree the process of freeing in this instance required an approach from the side of the condyle instead of that that of the tuberculum articulare. With the establishment of freeing of the joint the pa-tient was able to open and close his mouth at will.
