Computer-Assisted Surgery: An Aid to Orientation in Surgery of the Middle Cranial Fossa?1

“…Due to previous surgical procedures and the destructive nature of some of the diseases affecting the skull base, surgical landmarks are in techniques of CAS to neurosurgery and ear-nosethroat (ENT) surgery and gained first encouraging experiences. [5][6][7][8][9][10][11][12] Even though different commercially available CAS systems are based on different navigation principles (e.g., optical or electromagnetic), precise intraoperative orientation is provided by high-resolution imaging techniques (e.g., computed tomography (CT), magnetic resonance imaging (MRI)). Current indications for CAS in ENT are endoscopic or microscopic revision endonasal sinus surgery; the surgeon's experience; and surgery of the anterior and middle cranial fossae, infratemporal fossa, and retromaxillary space.…”

Computer-aided surgery (CAS) based on high-resolution imaging techniques represents an important adjunct to precise intraoperative orientation when anatomical landmarks are distorted or missing. Several commercial systems, mostly based on optical or electromagnetic navigation principles, are on the market. This study investigated the application of EasyGuide®, VectorVision®, and InstaTrak® CAS systems in ENT surgery under practical and laboratory conditions. System accuracy, time required, handling, individual features, and practicality were examined in 155 patients who underwent endonasal sinus surgery and in 23 patients who underwent anterior or lateral skull base procedures. The VectorVision® and InstaTrak® CAS systems proved to be suitable for routine application in surgery involving the paranasal sinuses and various regions of the anterior skull base by helping to avoid critical structures and to determine minimally invasive approaches.
