Minimally Invasive Cochlear Implantation Assisted by Bi-planar Device: An Exploratory Feasibility Study .

Background: A single drilled tunnel from the lateral mastoid cortex to the cochlea via the facial recess is essential for minimally invasive cochlear implant surgery. This study aimed to explore the safety profile of this kind of new image-guided and bi-planar device-assisted surgery procedure in vitro.

Methods: Image-guided minimally invasive cochlear implantations were performed on eight cadaveric temporal bone specimens.
