Temporal bone dissection simulation--an update.

We report on our continued development of a virtual simulation for temporal bone dissection that provides stereoscopic display, haptic feedback, and aural simulation into a straightforward, comprehensive learning environment. The multimodal interface provides a seamless simulation for non-deterministic drilling and cutting of bone in the surgical context, as well as an intuitive interface for the intelligent tutor for learning regional anatomy. We present novel methodologies for integrating multimodal and multiresolution data sets, including extension to functional and structural segmentation. We will present our initial efforts to validate this environment. Through continued iterations, it is our hope that the system will provide a valuable tool for training future otologic surgeons as well as an environment for the quantitative evaluation of surgical skill.

Virtual temporal bone dissection simulation.

We have developed a working prototype system for the virtual simulation of temporal bone dissection. The system offers a paradigm from traditional practices by integrating technological advances to provide a safer and more cost effective way to learn fundamental techniques used in temporal bone surgeries. We present our methods to provide a real-time interactive volumetric system that obviates the need for physical materials in initial training, and provides a more accessible way for residents to practice and to increase exposure to pathological variance. Finally, we discuss ways to extend this work to more advanced resident training, presurgical planning, and surgical documentation.

Traumatic intracavernous aneurysm in children: massive epistaxis without ophthalmic signs.

Traumatic intracavernous aneurysms are a distinctly uncommon lesion in children. They usually present with compressive symptoms of the III, IV, V, or VI cranial nerves rather than epistaxis. Epistaxis is rare and usually minor and brief in duration. A child with severe head injury and basal skull fracture, who did not have any preceding symptoms or signs of ophthalmoplegia or exophthalmus, developed massive epistaxis as a leading symptom of the ruptured intracavernous aneurysm. Since there are no reported pediatric cases with fatal epistaxis as a presenting sign, we would like to share our experience.
