Since 1980 we have used Tübingen middle ear implants of aluminum oxide in some reconstructions of the ossicular chain. So far such implants have been inserted in 129 operations on 106 patients. Follow-up examinations have been performed on 108 ears (91 patients). Post-operative observation periods have varied from 6 to 46 months, with an average duration of 22 months. In the last two years, since observing the first extrusions and imminent extrusions of implants, we have begun inserting a small autologous cartilage-perichondrium disk between implant and eardrum. Follow-up examinations have shown that insertion of cartilage lowers the rates of extrusion and imminent extrusion. It should be noted, however, that the average observation period for implants with cartilage has been somewhat shorter than for those without cartilage. Good audiometric results have been obtained with Al2O3-ceramic implants. Moreover, insertion of a cartilage-perichondrium disk demonstrably contributes to an improvement of audiometric results. As our clinical study shows, an Al2O3-ceramic implant is quite suitable for reconstructive surgery of the ossicular chain when an alloplastic implant is needed. At the same time we strongly advise insertion of a cartilage-perichondrium disk between the eardrum and the implant.
自1980年以来，我们在一些听骨链重建手术中使用了氧化铝材质的图宾根中耳植入物。到目前为止，已在106例患者的129次手术中植入了此类植入物。已对108只耳朵（91例患者）进行了随访检查。术后观察期从6个月到46个月不等，平均时长为22个月。在过去两年中，自从观察到首次植入物挤出和即将发生的挤出情况后，我们开始在植入物和鼓膜之间插入一小块自体软骨-软骨膜盘。随访检查表明，插入软骨可降低挤出和即将挤出的发生率。然而，应该指出的是，带有软骨的植入物的平均观察期比没有软骨的植入物略短。使用Al2O3陶瓷植入物已获得了良好的听力测量结果。此外，插入软骨-软骨膜盘显然有助于改善听力测量结果。正如我们的临床研究所示，当需要使用异体植入物时，Al2O3陶瓷植入物非常适合听骨链重建手术。同时，我们强烈建议在鼓膜和植入物之间插入软骨-软骨膜盘。
