以47例平均年龄32.5岁(10～70岁)的鼓膜前方或次全穿孔并累及前方鼓环的病人为研究组。耳后径路并取筋膜作移植物。在筋膜前部作二个平行切口以制成一个供牵引的短小突出部,将其置于耳道皮下隧道。并在基底上方增加切口使移植物易固定在槌骨柄的任何一侧。在切除穿孔边缘后,后方形成一个鼓膜耳道瓣和用内衬法使移植物固定。移植物前部小突出部由吸引器和镊子引出,通过隧道显示
47 patients (mean age 32.5 years (10 to 70 years) in front of the tympanic membrane or subtotal perforation and involvement of the anterior drum ring patients as the research group. Ear path and fascia for transplantation. Two parallel incisions were made in the anterior fascia to make a tab for traction, placing it in a subcutaneous tunnel of the ear canal. And increase the incision above the base so that the graft is easily fixed on either side of the shank. After removal of the perforation edge, a tympanic membrane of the ear canal is formed at the rear and the graft is fixed by the lining method. The anterior prominence of the graft is pulled out by an aspirator and forceps and displayed through a tunnel
