在我们对猪下鼓室的实验中，可吸收多孔磷酸三钙陶瓷已被证明可用于减少根治性乳突切除术中的空洞并可作为骨壁的替代品。在我们在中耳手术中使用多孔磷酸三钙陶瓷进行的初步临床试验中，我们专门制作了植入物，用于替换骨壁和减少根治性乳突切除术空洞。当使用植入物替代骨壁时，鼓室通气不足常常与植入物和耳道之间的覆盖物的并发症同时发生。后续手术为十五个植入物提供了组织学检查的机会，这些植入物用作墙壁替代物九到三十个月。只有最轻微的骨吸收和替代痕迹。与我们用陶瓷植入物替换墙壁的研究结果相反，长达四年的术后观察表明，多孔磷酸三钙陶瓷颗粒非常适合减少根治性乳突切除术蛀牙。
In our experiments on the hypotympanum of the pig, resorbable porous tricalcium phosphate ceramic has proved to be serviceable for reducing radical mastoidectomy cavities and as a substitute for osseous walls. For our initial clinical trials with porous tricalcium phosphate ceramic in middle ear surgery, we had implants made especially for the purposes of replacing osseous walls and reducing radical mastoidectomy cavities. When implants have been used to replace osseous walls, insufficient ventilation of the tympanic cavity has frequently coincided with complications in the covering between implant and auditory canal. Follow-up operations have afforded opportunities for histologic examination of fifteen implants, which served as wall replacements for nine to thirty months. There were only the slightest traces of resorption and replacement by bone. In contrast with our findings on the replacement of walls with ceramic implants, postoperative observation for periods of up to four years has shown that granules of porous tricalcium phosphate ceramic are well suited to reducing radical mastoidectomy cavities.
