鼓室成形术在欧洲趋向使用内衬法,其成功率一直保持在97％。前边缘性穿孔的主要问题是前鼓室耳道角。高位嵌入(外贴)技术易产生钝角,偶尔会发生鼓环胆脂瘤;内衬移植皮片易落入中耳腔的最深处——咽鼓管口处,尽管填充足量的明胶海绵。若提高前鼓环部分的移植物,又有产生前钝角之虞。Gerlach(1973)曾描述绗缝技术(quilting technique)以防止 Tympanoplasty in Europe tend to use lining method, the success rate has remained at 97%. The main problem with frontal perforation is the front tympanic canal angle. High embedded (paste) technology is easy to produce obtuse angle, and occasionally happen to drum cholesteatoma; lining graft skin easily fall into the depth of the middle ear cavity - eustachian tube orifice, despite filling a sufficient amount of gelatin sponge. If you raise the front part of the drum ring graft, there is the risk of pre-obtuse. Gerlach (1973) described the quilting technique to prevent it
