The ossified cochlea, although rare, represents a challenge for cochlear implantation. While it is no longer considered an absolute contra-indication to implantation, insertion may be technically difficult and the results may be suboptimal. Techniques which have been employed are reviewed. The new Digisonic multi-array implant, which was designed specifically for use in the ossified cochlea is described, along with the technique used for its insertion. In the first patient to be implanted with this new implant, all electrodes lie within the cochlea and are functional. The new Digisonic multi-array implant may have advantages over other solutions for the ossified cochlea.
骨化的耳蜗虽然罕见，但对人工耳蜗植入构成挑战。虽然它不再被视为植入的绝对禁忌证，但植入技术上可能有困难，结果可能不理想。本文回顾了已采用的技术。介绍了专门为骨化耳蜗设计的新型Digisonic多阵列植入物及其植入技术。在首例植入这种新型植入物的患者中，所有电极都位于耳蜗内且功能正常。新型Digisonic多阵列植入物相对于骨化耳蜗的其他解决方案可能具有优势。
