ムコーズス菌性中耳炎，特に錐體尖端化膿症の1治驗例

　緒言

　最近10年余りの間にけ於る我邦の文献を渉猟してみると，錐体蜂巣炎乃至錐体尖端化膿症の記載又は学会報告は甚だ多数であつて，本症の起炎菌としてムコーズス菌をあげてある報告も少くない．立木教授の宿題報告（昭和16年）には，ムコーズス菌中耳炎の際にみられた錐体尖端化膿症は13例で，その中死亡例は6例を数えてゐるが，ムコーズス菌中耳炎の研究の進歩に伴つて本症の病理も闡明された点が多いように感ぜられる．

　茲に報告せんとする症例は，昭和11年夏，松岡久藏博士指導のもとに診療したものであるが，最近西端教授が錐体炎の資料を募集されたので，この機会にその経過の大要を記し，特にX光線像を供覽する次第である．

Hata and his associates report a case of "mu-cosus" otitis media which, in spite of having instituted relatively early mastoidectomy, saw progress to infectious involemens of petrous py-ramid. A man 36 years old developed "muco-sus" otitis media. Myringotomy is performed on the tnird day of the disease which is follo-ved in turn with mastoidectomy on the 16th day. On the seventh post-operative day a discharge of pus under pulsation is discovered oozing from a sinus situated in the posterior, superior region above the superior semicircular canal. An X-ray picture is taken with injection of io-dized oil and insertion of a small sound in the sinus. As a paliative measure the sinus is en-larged at its outlet and the cavity in the pe-trous pyramid to which it lead is irrigated daily with "rivanol" solution. During this treatment the patient complained of otalgia, nocturnal hea-daches and deep ocular pains but, serious com-plications such as paralysis of external rectus muscles of the eyes are not manifested. The patient is cured in 3 1/2 months. Blood sedi. mentation tests that were made from time to time is stated to have served an excellent indications for the progress of the disease.
