传统鼓膜修补方法有内植法和外植法等,其中内植法最常用,适用于鼓膜后面部穿孔,优点是避免移植片外移,操作技术简单,缺点是易发生外耳道前角变钝和鼓室腔变小;外植法适用于各种穿孔,尤其适用于较大的和鼓膜前方穿孔,避免中耳含气腔缩小,但操作难度大。文章作者设计了一种新的鼓膜修补方法,即嵌入法(over and under tympanoplasty)。
The traditional tympanic membrane repair methods are implants and explants, etc., of which the most commonly used implant method for posterior tympanic membrane perforation, the advantage is to avoid the relocation of the graft, the operation technique is simple, the disadvantage is prone to external auditory canal anterior horn becomes dull and The tympanic cavity becomes smaller. The explant method is suitable for all kinds of perforation, especially for the larger perforation in front of the tympanic membrane and avoids the narrowing of the gas cavity in the middle ear, but the operation is difficult. The authors devised a new method of repair of the tympanic membrane, ie, over and under tympanoplasty.
