The treatment of cholesteatoma in patients without a permanent residence or in medically underdeveloped countries presents a serious problem in middle ear surgery. Methods which erradicate disease safely and reduce the risk of recurrence to a minimum are necessary. We differentiate 3 clinical types of cholesteatoma: 1 Retraction of Shrapnell's membrane or in the postero-superior quadrant with very little cholesteatoma lateral to the ossicles. A transcanal technique is used to evert the cholesteatomatous pocket into the meatus intact, followed by reconstruction of the outer attic wall. 2 Circumscribed cholestatoma lateral and often also medial to the ossicles. Combined approach tympanoplasty is used in such cases. 3 Marginal perforations with large cholesteatomas, situated medial to the ossicular chain. For these ears, classical radical mastoidectomy is the method of choice. (Radical mastoidectomy also has to be performed in all cases of type II, where luxation of the matrix in toto has failed.)
No recurrence has been detected in cases where follow-up was possible.
对于无固定居所的患者或医疗欠发达国家的患者,胆脂瘤的治疗在中耳手术中是一个严重问题。需要有能安全根除疾病并将复发风险降至最低的方法。我们将胆脂瘤分为3种临床类型:1. 鼓膜松弛部或后上象限内陷,听小骨外侧胆脂瘤极少。采用经耳道技术将胆脂瘤囊袋完整翻出至外耳道,随后重建上鼓室外侧壁。2. 听小骨外侧(通常也在内侧)的局限性胆脂瘤。此类病例采用联合进路鼓室成形术。3. 听骨链内侧有大的胆脂瘤的边缘性穿孔。对于这些耳朵,经典根治性乳突切除术是首选方法。(对于所有Ⅱ型病例,若基质完全脱位失败,也必须进行根治性乳突切除术。)
在可行随访的病例中未检测到复发。
