自体颞肌筋膜和软骨膜因其取材方便,存活率高,多年来一直是作为鼓室成形的移植材料。近年来有学者对鼓室成形术后的长期随访发现,部分患者术后可发生鼓膜回缩、听骨粘连,以及再穿孔;并认为用自体软骨-软骨膜复合物作为移植物,可以有效地防止鼓膜回缩、听骨粘连。为探讨自体软骨 Autologous temporal fascia and perichondrium have been used as tympanoplasty materials for many years because of their ease of application and high viability. In recent years, some scholars on the long-term follow-up after tympanoplasty found that some patients may occur after tympanic membrane retraction, ossicular adhesions, and re-perforation; and that the use of autologous cartilage - cartilage complex as a graft, can effectively prevent Tympanic membrane retraction, bone adhesion. To explore autologous cartilage
