Mastoidectomy: anatomical parameters x surgical difficulty

Surgical Findings in Revision Radical Mastoidectomy

Robotic mastoidectomy.

HYPOTHESIS Using image-guided surgical techniques, we propose that an industrial robot can be programmed to safely, effectively, and efficiently perform a mastoidectomy. BACKGROUND Whereas robotics is a mature field in many surgical applications, robots have yet to be clinically used in otologic surgery despite significant advantages including reliability and precision. METHODS We designed ...

Prostate cancer: anatomical and surgical considerations.

Sometimes the past has to be recalled for the present to be vindicated; this is the case with cancer of the prostate (CaP). I shall comment and enlarge upon some aspects of this pathology, which has reawakened the interest of European urologists after 3 0 years. The publications by Walsh et al. e .g . [ l ] . on radical prostatectomy using the nerve-sparing procedure, have indeed had an influen...

Surgical-anatomical Aspect of the Cricoarytenoid Joint

Surgical instrument guidance using synthesized anatomical structures

We present a new method of intraoperative, image-based surgical instrument guidance. The method has the potential to significantly improve visualization of intraoperative procedures that currently depend on fluoroscopic images for navigation. 3D information from preoperative computed tomography (CT) is fused with images of the instrument taken intraoperatively. Our approach employs synthesized ...
