目的 探讨使用内窥镜技术进行鼓膜成形术的可行性。方法 内窥镜法与常规烧灼法作对照，比较两组间术后２ 周及３ 个月鼓膜穿孔闭合情况及再穿孔情况的差别。结果 术后２ 周及３ 个月，内窥镜组的穿孔闭合耳数多于对照组（ Ｐ＜ ０－０１），穿孔闭合者纯音听力测定示语言频率平均气导听阈及骨气导差均在１０ｄＢ（ＨＬ）以内，无听力下降者；声导纳检查鼓室曲线均为Ａ型，鼓室压均在正常范围内。结论 内窥镜下鼓膜成形术是一种简便易行、愈合率高、安全有效的修补鼓膜穿孔的新方法。
Objective To explore the feasibility of using endoscopic technique for tympanoplasty. Methods The endoscopic method was compared with the conventional cauterization method. The differences between the two groups in the perforation and perforation of the tympanic membrane at 2 weeks and 3 months after operation were compared. Results The numbers of perforation and closing ears in the endoscopic group were more than those in the control group at 2 weeks and 3 months after operation (P <0-01). The pure tone audiometry of the perforator closed showed that the mean air-conduction hearing threshold 10dB (HL), no hearing loss; acoustic admittance examination tympanogram are type A, tympanic pressure are in the normal range. Conclusions Endoscopic tympanoplasty is a new and safe method to repair perforation of the tympanic membrane.
