自体颞筋膜鼓膜移植术的成功率高,但也存在两个缺点:外植时鼓膜前下方容易“变钝”和向外移位;给大穿孔作为内衬时穿孔率比较高。为了减少这些并发症,作者采用甲醛制备的自家颞筋膜来作鼓膜重建术。所谓鼓膜前下方的“变钝”,即外耳道前沟被增生组织所侵占,失去了正常的解剖间隙。大 The autonomic temporal fascia tympanoplasty has a high success rate, but has two drawbacks: the anterior and posterior tympanic membrane tend to “dull” and outwardly displaced when implanted; the perforation rate is high for large perforations as a liner. In order to reduce these complications, the author uses a home-made temporal fascia made of formaldehyde for eardrum reconstruction. The so-called front of the tympanic membrane under the “dull”, that is, the external auditory canal before the furrow by the proliferation of organizations occupied, lost the normal anatomical gap.
