33年的镫骨切除术和镫骨钻孔术250例比较,其中152例为镫骨足板切除,脂肪及金属丝赝复物重建;98例为镫骨钻孔特氟隆活塞重建,镫骨钻孔采用小开窗法,用人工或低速钻在足板后上方钻直径为5～6mm的小孔,安放直径为4mm的特氟隆活塞,再用脂肪封闭卵圆窗。250例手术中有33个患者为双耳手术。局麻、大多数用耳内切口,少数为耳前切口。术后3～6个月听力检查,并随访1年。经术前术后气骨导差距、气传导及语言接受率检查发现:术后气骨导差距在10dB以内者脂肪金属丝组占95%,其余5%在11～20dB;特氟隆活
33 cases of tarsal osteotomy and tarsal drilling 250 cases, of which 152 cases of stapes foot resection, fat and wire prosthesis reconstruction; 98 cases of tarsal drilling Teflon piston reconstruction, 镫Bone drilling using a small window method, with artificial or low-speed drilling in the foot above the top of the drill diameter of 5 ~ 6mm holes, placed a diameter of 4mm Teflon piston, fat and then closed the oval window. Thirty-three of 250 patients underwent binaural surgery. Local anesthesia, the majority of incisions with the ear, a small incision for the ear. 3 to 6 months after hearing, and follow-up for 1 year. After preoperative and postoperative air-air conduction difference, air conduction and language acceptance rate examination found that: the postoperative gap less than 10dB adipose metal wire group accounted for 95%, the remaining 5% at 11 ~ 20dB; Teflon live
