对传统的联合径路鼓室成形术式做了部分改进，并采用钛质听骨行听骨链重建，治疗胆脂瘤型中耳炎86例（89耳），随访18～50个月，未见胆脂瘤复发及耳蜗性听力损伤，鼓膜全部愈合。纯音听阈达到应用水平（语频平均30dBHL以上）者66耳（74％），骨气导差闭合（≤10dBHL）者56耳（63％），听阈无明显变化者10耳（11％），总有效（纯音听阈较术前降低10dBHL以上）者79耳（89％）。表明改进的术式对彻底切除病变，防止胆脂瘤残留和复发，扩大手术适应证，方便听力重建和改善鼓室功能具有重要意义。
86 cases (89 ears) of cholesteatoma otitis media were treated with titanium ossicular ossicular chain reconstruction. Some cases were followed up for 18 to 50 months. There was no bile fat Tumor recurrence and cochlear hearing loss, the tympanic membrane healed completely. Pure tone hearing threshold reached 66 ears (74%) with application level (average 30dBHL or above), 56 ears (63%) with closed air conduction difference (≤10dBHL) and 10 ears (11%) with no obvious change in hearing threshold (Pure tone threshold lower than preoperative 10dBHL) were 79 ears (89%). It shows that the improved operation is of great significance for the complete removal of lesions, prevention of residual and recurrence of cholesteatoma, expansion of surgical indications, ease of hearing reconstruction and improvement of tympanic function.
