真珠腫性中耳炎の遺残再発

Some Clinical Characteristics of Residual Cholesteatoma

I．はじめに

　真珠腫性中耳炎のために手術を受け長年月たってから再発したり，長い期間にわたって何度も再発を繰り返している症例を最近数例経験した。初回手術の例と違う点がいろいろあり，こうした症の検討は慢性中耳炎ことに真珠腫性中耳炎を手例の検討は慢性中耳炎ことに真珠腫性中耳炎を手術するものにとってさまざまな示唆を含んでいるので紹介したい。再発はすべて遺残によるもの（residual）で，再度陥凹して起こったもの（recur—rent）ではない。

Three cases of residual cholesteatoma were reported. The first patient developed vertigo 10 years after operation, resulting from a pulling of the pinna. The other two cases showed repeated recurrence. Although the ear structures were markedly deformed in all three cases, CT scan by target imaging provided adequate informations for operation. The authors conclude that long-term follow-up of 10 years or more is an important conjunct for a thorough treatment of cholesteato-matous otitis.
