摘要
目的评价内镜下修补干性鼓膜中、小穿孔的效果并与传统的烧灼法作对照。方法按完全随机法将鼓膜干性中央性中、小穿孔130耳分为两组,第一组100耳接受内镜下同种异体颞肌筋膜鼓膜成形术(内镜组),另30耳采用传统的40%三氯醋酸烧灼法进行修补(对照组)。比较两组间术后3个月鼓膜穿孔完全愈合的耳数以及术后6个月的语言频率纯音听阈的差异。结果术后3个月,内镜组鼓膜穿孔完全愈合率为91/100,较对照组的20/30高(P<0.01),术后6个月,两组鼓膜穿孔完全愈合者的骨-气导差在10dB以内的占90.1%。结论使用内镜修补鼓膜穿孔具有明显的优势,可代替手术显微镜且更容易通过狭窄或弯曲的外耳道,该手术是一种简单易行、安全有效的方法。
Objective To evaluate the results of myringoplasty under the endoscope in 130 patients with small-to-medium size of dry central perforation of the tympanic membrane, in comparison with that of the traditional cautery and patch method. Methods 130 cases were divided into two groups: one is with 100 ears treated by allogeneic fascia temporalis (endoscopic group) and the other 30 ears by the traditional cautery and patch method repeated at weekly intervals(control group). The difference between the two groups was compared. Postoperative audiograms were done at 6 months. Results 91% of the closure rate was achieved in endoscopic group, while only 20 of the 30 ears in control group had the results of perforation closure. The difference was significant(p<0.01). The air-bone gap was 10 dB or less in 90.1% of the cases with total closure of the perforations. Conclusion Repairing tympanic membrane perforations with endoscopic transcanal technique represents a significant advance. It replaces the microscope in closure of the tympanic membrane perforation and makes it easier to access the tympanic membrane in cases with stenotic and tortuous ear canal. It provides a simple, effective way to close the perforations of the tympanic membrane. '
