The use of homograft ossicles and homograft cortical bone has been common practice in chronic ear surgery for reconstruction of the interrupted ossicular chain. However, the possibilities of extrusion, reabsorption, and necrosis of these homografts have jeopardized the fate of such tissue for ossicular reconstruction. This study analyzes the fate of more than 400 homograft ossicles and bone columellas used for ossicular chain reconstruction over more than fifteen years, all of which were previously processed and sculptured in an ear bank. Many of these homografts have been observed for longer than five years. Histologic findings in longstanding homograft ossicles in the middle ear are presented.
同种异体听小骨和同种异体皮质骨用于慢性耳科手术以重建中断的听骨链已成为常用方法。然而，这些同种异体移植物出现挤压、再吸收和坏死的可能性危及了用于听骨重建的此类组织的命运。本研究分析了超过400个用于听骨链重建的同种异体听小骨和骨柱在超过15年中的转归情况，所有这些移植物均预先在耳库中进行处理和塑形。其中许多同种异体移植物的观察时间超过了5年。本文展示了中耳中长期存在的同种异体听小骨的组织学发现。
