In endoscopy, the visual information provided by the endoscopes combined with the surgeon’s experience and knowledge of anatomy as well as preoperatively generated radiology data sets establish the basis for the operative procedure. However, a prerequisite is – in addition to optimal endoscopic vision – precise orientation within the operative site. Extensive pathologies, scarring or altered anatomical conditions on account of previous surgeries can make it difficult to identify key structures that allow the maintenance of orientation within the operative site. This can affect the quality of the intervention and endanger the safety of the patient.
In such cases, support with spatial orientation is particularly helpful for the surgeon. The optical and electromagnetic navigation systems from KARL STORZ provide surgeons with excellent support in otorhinolaryngology and skull base surgery. During the procedure, the position of the instruments is continuously determined through optical navigation, where glass markers or reflectors are attached to the instruments, or electromagnetic navigation, where micro coils are integrated in the instrument tip.
Years of experience in instrument manufacture ensures the smooth and ergonomic integration of navigated instruments into the clinical routine.

The innovative planning software for new routes in FESS surgery
The NAV1® SINUSTRACKER™ planning software enhances the KARL STORZ NAV1® ELECTROMAGNETIC system with the automatic planning of access paths in paranasal sinus and skull base surgery. On the basis of a preoperatively set starting and destination point in the patient’s radiological data, the software allows the surgeon to determine a precise access path that is specially adapted to the individual anatomic structures of the patient.
The physician then reviews and modifies the suggested access path at his/her discretion. Intraoperatively, the selected route is visualized on the navigation screen so that the actual position in the site is under constant control.
Benefits of the NAV1® SinusTracker™
- Multiple Path Planning enables the preoperative planning and naming of up to eight access paths and alternatives
- Intraoperative visualization and control of access paths
- Less preoperative planning required thanks to automatic preplanning
- Flexible, pre- and intraoperative adaptation of the access path possible
NAV1® Endoscope Tracker
Augmented FESS endoscopy with the new electromagnetic navigated endoscope adaptor
Using augmented endoscopy, which was specially developed for the NAV1® SinusTracker™, the real-time endoscopic image can be enhanced with information obtained from the preoperative virtual planning of the access route. Adaptor is used in conjunction with KARL STORZ HOPKINS® telescopes with 0°, 30° or 45° directions of view for augmentation. The position and direction of view of the employed telescope is displayed in the radiology images in such a way that the endoscopic image can be precisely assigned to the exact location in-situ.
Benefits of augmented endoscopy
- Possible to display planning elements in the standard endoscopic image
- Visual navigation of non-navigated instruments along the preoperatively planned route
- Spatial mapping of the direction of view and the position of the telescope in the site
