用各种不同人工材料修补鼓膜穿孔以改善听力迄今已200余年。已知不同人工材料包括各种聚合物和生物膜亦各有其不同的缺点。特别是对中、老年患者行听力增进手术多数耳科学家认为不太适宜。为此,作者选用软磁性弹性膜片对30例中、老年患者(51～75岁)鼓膜干性穿孔进行修补。病例选择:保持干耳6月以上,紧张部中央穿孔,槌骨柄完好;或紧张部大穿孔,但鼓膜残边离鼓环至少在2mm以上;咽鼓管通畅,鸡蛋膜贴补穿孔听力有改善者。凡符合上述条件的Ⅰ～Ⅱ度传音性或混合型重听患者,均可用此法修补穿孔之鼓膜。本组30例中有双耳膜干性穿孔6例,一耳干性穿
With a variety of different artificial materials to repair tympanic membrane perforation to improve hearing so far has been 200 years. Known different artificial materials including various polymers and biofilms also have their own different drawbacks. Especially for middle-aged, elderly patients with hearing enhancement surgery most ear scientists think not appropriate. To this end, the author selected soft magnetic elastic membrane in 30 cases of elderly patients (51 to 75 years old) to repair the dry perforation of the eardrum. Case selection: keep ear dry more than 6 months, central nervous central perforation, mallet handle intact; or Department of large perforation, but the tympanic membrane from the drum ring at least 2mm above the residual; Eustachian tube patency, . Where meet the above conditions Ⅰ ~ Ⅱ degree acoustic or mixed type re-hearing patients, can be used to repair the perforation of the tympanic membrane. The group of 30 patients with dry ears perforation in 6 cases, one ear dry wear
