Since 1956, 1,540 tympanomastoidectomy procedures for cholesteatoma or chronic suppurative otitis media with mastoiditis have been performed; 180, done from 1972 through 1980, were reviewed in detail for effectiveness of surgery, control of disease, and hearing results. The majority of the procedures were done for cholesteatoma. Almost all of these had preoperative sclerotic or poorly developed mastoids as judged by x-ray examination. A limited open-cavity technique with one-stage tympanic repair has resulted in long-term control of cholesteatoma in the mastoid segment in almost every case and reasonable success in control of middle ear disease and preservation or improvement in hearing. Properly performed modified radical mastoid cavities seldom cause problems in postoperative care, do not preclude swimming, and do not impair concomitant tympanoplastic repair. Failure to control disease in the middle ear or to improve hearing is the major problem. Revision tympanoplasty can correct some of these remaining problems, but is usually an elective procedure.
自1956年以来，已进行了1540例针对胆脂瘤或伴有乳突炎的慢性化脓性中耳炎的鼓室乳突切除术；对1972年至1980年期间所做的180例手术进行了详细回顾，以评估手术效果、疾病控制情况及听力结果。大多数手术是针对胆脂瘤进行的。通过X线检查判断，几乎所有这些病例术前乳突均为硬化型或发育不良。采用一期鼓膜修复的有限开放腔技术几乎在每例患者中都实现了对乳突段胆脂瘤的长期控制，在中耳疾病控制及听力保留或改善方面也取得了合理的成功。正确施行的改良乳突根治术很少在术后护理中引发问题，不影响游泳，也不会妨碍同期鼓膜成形术修复。未能控制中耳疾病或改善听力是主要问题。翻修鼓膜成形术可纠正部分遗留问题，但通常是一种选择性手术。
