About

Ph. A. Federspil is a pioneering figure in otorhinolaryngology whose work bridges the gap between advanced robotics and hearing restoration. His research focuses on two transformative areas: active hearing implants and robotic-assisted surgery of the lateral skull base. Federspil’s major contributions include demonstrating the feasibility of robotic milling for precise implant bed preparation in human skull bones, using a serial robot (Stäubli RX 130) enhanced by force, momentum, and temperature sensors. He also advanced ultrasound-based navigation to improve the accuracy and safety of robotic drilling in complex anatomical regions. His most cited work, “Restoring Hearing with Active Hearing Implants” (2004, 20 citations), critically analyzes the limitations of conventional hearing aids—such as acoustic feedback, occlusion, and stigmatization—and advocates for active implants as a superior alternative. With over 50 combined citations across his key papers, Federspil’s research has laid foundational groundwork for integrating robotics into otoneurosurgery, offering new possibilities for high-precision, minimally invasive procedures. His achievements highlight a career dedicated to overcoming technical and psychological barriers in hearing restoration.
