Simultaneous Image-Guided Skull Bone Tumor Resection and Reconstruction With a Preconstructed Prosthesis Based on an OsiriX Virtual Resection.

Background: Skull reconstruction can be challenging due to the complex 3-dimensional shape of some structures, such as the orbital walls, and for cases involving a large cranial vault. In such situations, computer-assisted design and modeling of prostheses is especially helpful to achieve an adequate reconstruction. Simultaneous tumor resection and skull defect reconstruction are also challenging because the preoperative imaging does not display the anticipated defect.

A neuronavigation-based method for locating the superficial temporal artery during extra-intracranial bypass surgery.

The superficial temporal artery (STA) is frequently used as donor vessel in extracranial to intracranial bypass surgery. Current techniques typically rely on a Doppler vascular probe to identify the STA trajectory prior to the skin incision; however, this step can be time consuming and difficult when the arterial course is tortuous. We tested an alternative neuronavigation-based technique for locating the STA.

The mirroring technique: a navigation-based method for reconstructing a symmetrical orbit and cranial vault.

Background: The reconstruction of orbital structures and the cranial vault curvature can be challenging after trauma or wide resections for tumors. Sophisticated methods have been developed recently, but these are resource- and time-consuming.

Objective: We report the mirroring technique, which is an effective and costless application for navigation-guided reconstruction procedures.
