When otitic cholesteatomas are removed by a surgical method that preserves or reconstructs the bony canal wall and tympanic membranes, there is a risk of imcomplete removal and possible regrowth of the lesion. To study the incidence of this complication, 52 patients with cholesteatoma had elective repeaated explorations at various postoperative intervals; eight (15.4%) had early cholesteatoma regrowth even though there was no clinical evidence of it. Seven of these regrowths were small and were again srugically removed. It is advocated that conservative surgery for cholesteatoma be followed up in two years by another elective surgical exploration to check for and dispose of possible cholesteatoma regrowth. This would provide safety comparable to that achieved with radical mastoidectomy, with far better function and hearing. The method does necessitate patient understanding and cooperation and I suggest methods of achieving this.
当采用保留或重建骨管壁及鼓膜的手术方法切除耳源性胆脂瘤时，存在病变切除不完全及可能复发的风险。为研究这一并发症的发生率，52例胆脂瘤患者在术后不同时间进行了选择性再次探查；8例（15.4%）出现了早期胆脂瘤复发，尽管当时并无临床证据显示复发。其中7例复发灶较小，再次通过手术切除。主张对接受胆脂瘤保守手术的患者在两年后进行另一次选择性手术探查，以检查并处理可能的胆脂瘤复发。这将提供与根治性乳突切除术相当的安全性，同时功能和听力要好得多。该方法确实需要患者的理解与配合，我将提出实现这一点的方法。
