ReviewRecent advances in cerebrovascular simulation and neuronavigation for the optimization of intracranial aneurysm clipping.
Endovascular treatment of intracranial aneurysms (IAs) has improved to the extent that in some instances such an approach has now become safer than surgery. This has dramatically changed clinical practice by reducing the volume and increasing the complexity of IAs referred for open surgical treatment. We review the simulation techniques and dedicated vascular neuronavigation systems that have been developed to maintain the quality of aneurysm clipping in this context. ⋯ These help make the operation secure by accurately predicting the location and orientation of an aneurysm within its parenchymal and vascular environment. Future simulators dedicated to cerebrovascular procedures will need to integrate representation of the brain surface and biomechanical modeling of brain and aneurysm wall deformation under retraction or during clipping. They should contribute to training and maintenance of surgical skills, thereby optimizing the quality of surgical treatment in this field.

Review Comparative StudyRobotics in urological surgery: review of current status and maneuverability, and comparison of robot-assisted and traditional laparoscopy.
To assess the current state of robot-assisted urological surgery, the literature concerning surgical robotic systems, surgical telemanipulators and laparoscopic systems was reviewed. Aspects of these systems pertaining to maneuverability were evaluated, with a view to quantifying their stability and locomotive properties and thereby determining their suitability for use in assisted laparoscopic procedures, particularly robot-assisted laparoscopic urological surgery. The degree of maneuverability and versatility of a robotic system determine its utility in the operating room, and the newer-generation surgical robotic systems have been found to possess a higher degree of maneuverability than older class 1 and class 2 systems. It is now clearly established that robots have an important place in the urologist's armamentarium for minimally invasive surgery; however, the long-term outcomes of several urological procedures (other than robot-assisted radical prostatectomy) performed with the da Vinci surgical robotic system have yet to be evaluated.

ReviewVirtual 3D planning and guidance of mandibular distraction osteogenesis.
We present a system for 3D planning and pre-operative rehearsal of mandibular distraction osteogenesis procedures. Two primary architectural components are described: a planning system that allows geometric bone manipulation to rapidly explore various modifications and configurations, and a visuohaptic simulator that allows both general-purpose training and preoperative, patient-specific procedure rehearsal. We provide relevant clinical background, then describe the underlying simulation algorithms and their application to craniofacial procedures.
