Preclinical Study of a Minimally Invasive Cochlear Implant Device Based on 3D Printing of a Custom Guide

The results of this feasibility study demonstrated that the precision of this guide was close to the target of less than 0.5 mm, with reassuring safety data regarding critical anatomical structures. It therefore seems worthwhile to pursue the development of the procedure with a larger-scale study, using more precise, high-performance software and cochlear implantation equipment and assessing the quality of electrode insertion.
