INTRAOPERATIVE TRACKING AND POSITIONING OF TRANSNASALLY INSERTED DEVICES

摘要

Methods and systems for performing procedures within the ear, nose throat or paranasal sinus and/or for determining the current position of a trans-nasally inserted device within the body of a human or animal subject. A pre-operative tomographic image is obtained prior to the procedure and displayed on a display. A working device is inserted through the subjects nostril and an intra-operative tomographic imaging device is then used to obtain one or more intra-operative tomographic images (e.g., showing the position/effects of the working device within the body, changes to anatomical structures of interest, other desired structures, etc.). A processor receives data from the intra-operative tomographic imaging device and either i) replaces the pre-operative tomographic image with the intra-operative tomographic image or ii) integrates the intra-operative tomographic image into the pre-operative tomographic image, thereby updating the tomographic image viewed on the display.
