Radical obliterative cholesteatoma surgery was performed on 463 ears. Post-operative cholesteatomas were found in 22 of 463 of the ears during the follow-up periods that ranged from five to 15 years. Eight of them were of the residual type, and 14 were of the recidive type. A substantial portion of the postoperative cholesteatomas (11 cases) was discovered as late as the sixth to the tenth postoperative years. Four of the postoperative cholesteatomas extended to the antrum or the operation cavity from the tympanic cavity or meatus, but none of them originated in the cavity area. The surgical method that was used was safe. Annual follow-up examinations for at least ten years are recommended after the obliterative radical operation for ears with cholesteatomas.
对463耳进行了根治性胆脂瘤清除术。在5至15年的随访期内，463耳中有22耳发现术后胆脂瘤。其中8耳为残留型，14耳为复发型。相当一部分术后胆脂瘤（11例）直到术后第6至10年才被发现。4例术后胆脂瘤从鼓室或外耳道延伸至鼓窦或术腔，但均非起源于术腔区域。所采用的手术方法是安全的。对于患有胆脂瘤的耳朵，在进行根治性清除术后，建议至少进行十年的年度随访检查。
