Surgical application of a new robotic system for paranasal sinus surgery

The applicability of a robotic system for fully automated surgical procedures approaching the sphenoid sinus is evaluated. An integrated robotic system, A73, for computer navigation-guided, fully automated, and telemanipulation robotic performance is described. Details of the system comprising newly designed surgical instruments for robotic operations and preoperative planning protocols are provided. Experiments with an operational accuracy of less than 1 mm were followed by surgical tests, in which the results of fully automated and telemanipulation performances on 5 cadaveric heads are seen. The A73 system has been successfully used for a reproducible and accurate resection of the anterior wall of the sphenoid sinus. Therefore, we conclude that this system is suited for further testing toward approaching fully automated and more complex procedures of paranasal surgery.
