    ABSTRACT: Surgical innovation relies on patient safety and quality of life, which require a drastic iatrogenic impact reduction. A parallel development toward less invasive approaches has occurred in the field of surgery, interventional radiology, and endoscopy. Minimally invasive techniques provide unquestionable benefits to patients in terms of postoperative outcome. However, those techniques are not intuitive, and extensive training is required to overcome the inherent challenges and to be proficient and consequently to achieve a steep learning curve. Technologies have been developed by computer science and robotics departments, which might improve minimally invasive techniques. A new concept of cyber therapies is emerging through the development of computer and robotic sciences aiming at human-machine integration. Additionally, the convergence of surgery, endoscopy, and interventional radiology toward a hybrid therapeutic modality, namely image-guided minimally invasive procedures, holds promises insofar as they could well maximize benefits in terms of efficacy and iatrogenic impact. In the present manuscript, the mainstays of these new paradigm developments are briefly outlined in light of our experience and vision of the future.

    ABSTRACT: Computer-assisted surgery is a wide field of technologies with the potential to enable the surgeon to improve efficiency and efficacy of diagnosis, treatment, and clinical management. This review provides an overview of the most important new technologies and their applications. A MEDLINE database search was performed revealing a total of 1702 references. All references were considered for information on six main topics, namely image guidance and navigation, robot-assisted surgery, human-machine interface, surgical processes and clinical pathways, computer-assisted surgical training, and clinical decision support. Further references were obtained through cross-referencing the bibliography cited in each work. Based on their respective field of expertise, the authors chose 64 publications relevant for the purpose of this review. Computer-assisted systems are increasingly used not only in experimental studies but also in clinical studies. Although computer-assisted abdominal surgery is still in its infancy, the number of studies is constantly increasing, and clinical studies start showing the benefits of computers used not only as tools of documentation and accounting but also for directly assisting surgeons during diagnosis and treatment of patients. Further developments in the field of clinical decision support even have the potential of causing a paradigm shift in how patients are diagnosed and treated.

    ABSTRACT: Through three-dimensional real time imaging, augmented reality (AR) can provide an overlay of the anatomical structure, or visual cues for specific landmarks. In this study, an AR Toolkit was used for distraction osteogenesis with hemifacial microsomia to define the mandibular osteotomy line and assist with intraoral distractor placement.Methods20 patients with hemifacial microsomia were studied and were randomly assigned to experimental and control groups. Pre-operative computed tomography was used in both groups, whereas AR was used in the experimental group. Afterwards, pre- and post-operative computed tomographic scans of both groups were superimposed, and several measurements were made and analysed.ResultsBoth the conventional method and AR technique achieved proper positioning of the osteotomy planes, although the AR was more accurate. The difference in average vertical distance from the coronoid and condyle process to the pre- and post-operative cutting planes was significant (p < 0.01) between the two groups, whereas no significant difference (p > 0.05) was observed in the average angle between the two planes. The difference in deviations between the intersection points of the overlaid mandible across two cutting planes was also significant (p < 0.01).Conclusion This study reports on an efficient approach for guiding intraoperative distraction osteogenesis. Augmented reality tools such as the AR Toolkit may be helpful for precise positioning of intraoral distractors in patients with hemifacial microsomia in craniofacial surgery.
