Abstract：
UNASSIGNED: Tympanoplasty is the most common operation performed by an Otolaryngologist worldwide.Type 1 tympanoplasty involves repair of pars tensa of tympanic membrane, when the middle ear is normal. The most widely used method is underlay technique using temporalis facia. In buttonhole tympanoplasty, the temporalis fascia is anchored to the handle of malleus through the buttonhole.
UNASSIGNED: To compare and analyze graft uptake and hearing outcome in button hole technique and underlay technique.
UNASSIGNED: It is a comparative study done at tertiary care center, where patients suffering from tubotympanic type of chronic otitis media with medium sized perforation with moderate conductive hearing loss, within age group of 18-60 years,were selected.
UNASSIGNED: In Button hole tympanoplasty group the mean hearing gain was 9.3dB, and 8.17 dB in Underlay tympanoplasty group which was statistically significant (p < 0.05) but P value between Button hole and Underlay tympanoplasty was not statistically significant.With regard to graft uptake 96.7% showed graft uptake in Buttonhole tympanoplasty group and in underlay tympanoplasty the graft uptake was 93.3%.
UNASSIGNED: Buttonhole technique is better in terms of graft uptake since the graft is anchored to the handle of malleus, and postoperatively medialisation of graft and other complications like lateralization of graft, epithelial pearl formation and anterior blunting is prevented. Both techniques are good in terms of hearing improvement for chronic otitis media with medium sized perforation with moderateconductive hearing loss.

摘要：
■鼓室成形术是全世界耳鼻喉科医师最常见的手术。1型鼓室成形术包括鼓膜筋膜修复，当中耳正常时。最广泛使用的方法是使用颞肌的底层技术。在扣眼鼓室成形术中，颞肌筋膜通过钮孔固定在锤骨的手柄上。
■比较和分析纽扣孔技术和底层技术中的移植物摄取和听力结果。
■这是一项在三级护理中心进行的比较研究，患有鼓室型慢性中耳炎，中等大小穿孔，中度传导性听力损失的患者，年龄在18-60岁之间，被选中。
■在按钮孔鼓室成形术组中，平均听力增益为9.3dB，鼓室鼓室成形术组8.17dB差异有统计学意义(p<0.05),而纽扣孔与鼓室成形术组P值差异无统计学意义。关于移植物吸收，在Buttonhole鼓室成形术组中显示移植物吸收96.7％，在下层鼓室成形术中，移植物吸收为93.3％。
■由于移植物固定在锤骨的手柄上，因此在移植物吸收方面，Buttonhole技术更好。术后移植和其他并发症，如移植的侧化，防止上皮珍珠形成和前钝化。两种技术在改善慢性中耳炎，中等大小的穿孔和中等程度的听力损失方面都很好。
