Two different prototypes of columella materials made from aluminum oxide ceramics were newly designed by the author for ossicular reconstruction. CORP-P (ceramic ossicular replacement prosthesis-partial) is used as a columella to fit onto the stapes head, and CORP-T (ceramic ossicular replacement prosthesis-total) is used as a columella placed onto the footplate of the stapes. In addition to the general properties of ceramic implants, CORP has these two characteristics: the unique shape of its head, which allows easy and smooth contact with the fascia graft, and the radiopacity, which makes it possible to confirm the position of the implants by x-ray examination after implantation.
作者新设计了两种由氧化铝陶瓷制成的用于听骨重建的小柱材料原型。CORP-P（陶瓷听骨置换假体-部分）用作小柱，以适配镫骨头，而CORP-T（陶瓷听骨置换假体-整体）用作放置在镫骨足板上的小柱。除了陶瓷植入物的一般特性外，CORP还具有这两个特点：其头部独特的形状，便于与筋膜移植物轻松、平滑地接触；以及不透射线，这使得在植入后通过X射线检查能够确认植入物的位置。
