中耳炎手術後に残存せられた含気蜂窠の態度に就いて

　緒言

　従来の耳手術学の歴史を見ると，先ず乳樣洞，或は中耳腔の膿汗を排泄させる目的で，antrotomieがなされたが，次第に全含気蜂窠の鑿開をなさぬば結果が悪いという事が主張され，一般に認められて来て居る．しかしながら，錐体含気蜂案に対する考察はあまりなされて居らず，ただ，Zaufall，或はStacke氏中耳根治手術に止め，あとは自然治癒に頼つて居る人が多い．

　果して乳樣突起，或は中耳腔に於いては残存されてはならぬ含気蜂窠が，錐体に於いては保存的に取扱われて良いものであろうか．

　NIHO and YOSHIO found by reoperation on 35 cases of simple mastoidectomies which had been performed previously but had failed to recover from such symptoms, as aural discharges, headaches, dizziness and tinitus, the cause of such failures to be air cells which had escaped the notice in the previous operation and epithelial linings which had been formed in them since then. In view of this fact the authors stress, in performing mastoidectomies, the importance of extenterating all possible air cells that may be present which might include among them the cells of the petrous pyramid.
