Ninety-nine ears of otitis media with cholesteatoma were operated from October 1982. The indications for different techniques and staging principles were discussed in detail. One to four years' postoperative observation in 72 ears proved that residual cholesteatoma could be controlled to 1.4%. Patients undergone intact wall technique had maintained almost normal ear structure. With the open cavity technique, a large external auditory meatus was created with perfectly healed drum. Auditory results indicated that 66.5% of patients had hearing gain greater than or equal to 10 dB with 41.7% air-bone gap less than or equal to 20 dB.
自1982年10月起，对99例胆脂瘤型中耳炎患者进行了手术。详细讨论了不同手术技术的适应证和分期原则。对72例患者进行了1至4年的术后观察，结果显示残余胆脂瘤的发生率可控制在1.4%。采用完壁式手术的患者耳部结构基本保持正常。采用开放式手术时，可形成较大的外耳道，鼓膜愈合良好。听力结果显示，66.5%的患者听力提高大于或等于10 dB，41.7%的患者气骨导差小于或等于20 dB。
