  • Highlights
    • a new concept for a surgical targeting system is prosposed
    • cost-effective, easy-to-use approach for accurate instrument guidance
    • mean positioning error was found to be 0.41 mm (SD: 0.30mm)
    • drilling was possible with an mean accuracy of 0.35mm (SD: 0.29mm)
    • demonstration of sufficient accuracy (0.35mm +/- 0.30mm) for many surgical applications

  • Highlights
    • µCT imaging and analysis of intracochlear geometrical variations
    • 15 detailed, 3D cochlear models investigated in terms of scalae height, cross-sectional size, and rotation
    • strong intracochlear anatomical variations could be observed
    • demand for highly flexible and self-adapting cochlear implant electrode array design
