颞筋膜是鼓室成形术中最常用的人工鼓膜材料,缺点是柔软不成形,修补鼓膜大穿孔时,难以在移植床上准确地铺放。目前多采用室温干燥脱水的方法,但当铺放时间稍延长,干燥的筋膜即吸水膨胀,仍不便铺放。1984年以来,我们采用酒精脱水颞筋膜,因能达到定形,铺放较方便,其鼓膜成活率与室温干燥的颞筋膜无差异。多次光镜 Temporal fascia is the most commonly used tympanoplasty artificial tympanic membrane material, the disadvantage is soft and not forming, repairing tympanic membrane perforation, it is difficult to accurately place the transplant bed. The current method of dehydration at room temperature to use more, but when the shop a little extended time, dry fascia that is water-swelling, is still not easy to lay. Since 1984, we use alcohol dehydration of the temporal fascia, because it can reach the shape, laying more convenient, the tympanic membrane survival rate and room temperature drying of the temporal fascia no difference.
