Scientists develop biocompatible materials for ossicular implants using 3D printing technology

Conductive deafness refers to various causes of ossicles / ossicles (ossicles) trauma damage caused by hearing loss, ossicular chain is attached to the cochlear bone structure, the eardrum can be converted to the auditory vibration signal transduction Auditory nerve Conductive deafness can be treated with artificial ossicles, but due to the different sizes of the ossicles in each patient, it takes a lot of time to manually abrade the implant during surgery and the failure rate is high.

The research team at the University of Maryland, led by Dr. Jeffrey D. Hirsch, uses 3D printing technology to achieve a precisely matched ossicular implant. In the experiment, the research team extracted the ossicles of the ossicular structure from three bodies And use this as a prototype to reconstruct the complete models of these cadaveric ossicular chains using CT scanning and computer technology and to construct low-cost 3D implants for these orthotopic implant devices. In surgical procedures on cadaveric bodies, The replanted 3D printed ossicular chain structure completely matches these dead bodies.

Now, the research team is planning to print these ossicular structures with biocompatible materials, and in the future they hope to make up for the damaged native ossicles with biocompatible materials that can be replaced by stem cell-regenerated bone cells. "This The research demonstrates the core medical power of 3D printing technology in implanting biocompatible implants into subtle biological anatomical spaces that can be gradually replaced by natural bones that grow.
