摘要


醫源性膽脂瘤乃因前次非膽脂瘤之中耳手術所造成,以前很少被提及,一方面是前次手術造成膽脂瘤的原因不易被確定,另一方面則牽涉了醫學倫理的問題,目前普遍認為由扁平上皮經軟組織缺損處誤植入而形成和平醫院耳鼻喉科於1997年4月,7月和9月經歷3例醫源性膽脂瘤,1例為手術中外耳道損傷,1例為中耳通氣管植入或移除後,另1例為植入物(筋膜)放置不當所造成,3例皆為術後發現,且經病理診斷證實,術後病人聽力進步,目前門診追蹤下,無復發之跡象。

Iatrogenic Cholesteatoma is defined as a new cholesteatoma after previous surgery for non-cholesteatomatous middle ear disease. It was seldom discussed before because its pathologic mechanism was difficult to he defined. In addition, medical ethical problem was also a consideration. Implantation of squamous epithelium into pneumatized portions of the temporal bone during the surgery was thought to be a major cause. We encountered 3 cases of iatrogenic cholesteatoma in 1997. One case was due to external auditory canal skin defect. The other two cases were related to a previous gromment insertion, and inadequate fascia grafting respectively. They were all confirmed by pathologic diagnosis after surgery. And there has been on evidence of recurrence until now.
