Introduction: For successful cochlear implantation in difficult ears, image guided navigation systems can help identify surgical landmarks or confirm the surgeon's anatomical knowledge. In this pilot case study, exact navigation based on intraoperative CT scanning was investigated and helped confirm important and necessary landmarks, such as the facial nerve, cochlea and intracochlear structures, and at least adequate placement of a straight electrode array.
Material And Methods: Intraoperative imaging was performed on a 40-slice sliding-gantry CT scanner (Siemens SOMATOM Sensation 40 Open) with an expanded gantry bore (82 cm).
