1986年至1989年间,240例需行Ⅲ型鼓室成形术慢性化脓性中耳炎患者中,145例取颞肌筋膜行鼓膜-镫骨连接术(1组)。经耳后进路行鼓室乳突根治术,术中去除所有隐蔽病变,尤其是前鼓室、上隐窝、鼓窦和下鼓室的病变。再将筋膜贴于完整的镫骨上。另外95例行鼓膜-软骨-镫骨连接术(2组)。作耳后切口,彻底清除乳突病变,修低面神经嵴至外耳道底平面。从耳屏取软骨软骨膜移植物,将周边的软骨去除,使其成为连于软骨膜之上的岛状,3×3mm~2,盖于镫骨尖上;软骨膜前边伸入鼓膜残边之下,后部盖于面神经嵴上,并以外耳道后壁扭转皮瓣覆盖之,以供给血液。外耳道填以
Of the 240 patients with chronic suppurative otitis media who underwent type III tympanoplasty between 1986 and 1989, 145 patients underwent eardrum-tympanotomy (group 1) with temporal fascia. The tympanic mastoidectomy via the posterior approach, removal of all hidden lesions, especially in the front tympanic cavity, upper sinuses, sinus and lower tympanic lesions. Then fasten the fascia to the full stapes. Another 95 cases of tympanic membrane - cartilage - tarsal connection (2 groups). After the ear incision, complete removal of papilla lesions, repair facial nerve ridge to the bottom of the ear canal plane. Cartilage from the tragus peritoneal graft, remove the surrounding cartilage, making it even connected to the perichondral island, 3 × 3mm ~ 2, covered in the tip of the stapes; perichondral anterior margin into the tympanic membrane Under the back of the cover in facial nerve crest, and the outer wall of the posterior wall of the skin twisted to cover the supply to the blood.
