Exploration of Navigation Simulator Applying in Maritime Trial

Navigation simulator is a product of highly developed maritime technology, the STCW 78/95 Convention puts forward the corresponding requirements on the application of the navigation simulator. This paper analyzes the current applying status of navigation simulator, discusses the professional technical characteristics of maritime cases and limitations of traditional maritime trial, points out the relative hysteresis quality of the maritime trial in application of navigation technology, and makes a prospect for the application of navigation simulator in trial maritime, including assisting the judges to ascertain the facts of cases and fix the evidence to promote case hearing rapidly and improve the scientific judgment.

Clinical use of a neuronavigation system in hemangioblastoma resection of posterior cranial fossa

The aim of this study was to retrospectively evaluate the effectiveness of the Stryker Leibinger neuronavigation system in surgical resection of hemangioblastomas of the posterior fossa. The study included 16 cases of solid hemangioblastoma of posterior cranial fossa treated since we began using Stryker Leibinger neuronavigation system-assisted microneurosurgery in 2003. These cases were compared on the basis of time, blood loss, and complications to 19 similar cases of solid hemangioblastoma that underwent conventional microneurosurgical resection prior to 2003. All patients in the experimental (neuronavigation-assisted) group underwent surgical resection without complications while the control groups' resections all involved blood loss related to the longer operation time. Neuronavigation also resulted in a clear field of surgical vision and clear lesion boundaries, making it easier to remove lesions and reduce accidental injury of adjacent normal structures. The application of navigation technology is very valuable for solid hemangioblastoma operations not only by shortening operative time, thereby significantly reducing operative blood loss, but also by making surgical excision easier, reducing damage to adjacent normal structures, and decreasing surgical complications and mortality.

On ``Evaluation of the Contribution of CAS in Combination with the Subcranial/Subfrontal Approach in Anterior Skull Base Surgery'' (Skull Base 2001;11:59-76)

Laedrach et al. recently published a study on the usefulness of navigation technology in anterior skull base surgery (Evaluation of the contribution of CAS in combination with the subcranial/subfrontal approach in anterior skull base surgery. Skull Base 2001;11:59-76). The authors presented 31 cases of various pathologies, including 6 mucoceles treated through an extensive subcranial-subfrontal approach, in most cases with a large coronal skin incision. At the end of the operation the skull defects were reconstructed by painstaking osteosynthesis. With this wide-open approach, the authors concluded that the application of navigation technology was valuable in only 23% of the cases and that this novel computer-based equipment should be used in a restricted manner.
