The group “Computer-Assisted Surgery and Electrode Development” (CAS-hno) is an interdisciplinary research group of engineers, physicians, and natural scientist at the Department of Otolaryngology whose common focus is the development of technologies and methods for surgical rehabilitation of the inner ear (cochlea).
This includes research activities dedicated to the design and development of surgical assistance devices in order to improve surgical techniques - with special focus on the minimally invasive access to the inner ear. Based on high-resolution imaging and pre-operative patient-specific planning different technologies of image-guided surgery systems, mechatronic assistance devices as well as micro-stereotactic frames are incorporated into the surgical workflow for a highly accurate and less traumatic surgical intervention.
The second research focus lies on the improvement of the electrode array of a cochlear implant (CI) including the insertion technique. In this field, our research group covers the complete design and development process. Starting with imaging and three-dimensional (3D) modelling of the human inner ear, the methods used include: development of improved electrode designs using computer aided design (CAD) software and finite element analysis (FEA); the simulation and optimization of the insertion process; experimental characterization of the electrode arrays by manual and/or automated insertion in artificial cochlear models and/or temporal bone specimens. Of special interest is the functionalization of the electrode array by integrating of actuators (e.g. using shape memory materials, fluid mechanical actuators, and tubular manipulators) for an individual adaption of the shape of the implant to the helical shaped inner ear in order to improve hearing preservation.
