In endoscopy, the surgical procedure is chosen based on a combination of visual information supplied by the endoscope, the surgeon's anatomic knowledge and experience, and preoperative radiology data. However, this requires an optimal endoscopic image as well as precise orientation within the surgical field. Extensive pathologies as well as scarring and changes resulting from previous surgeries can significantly complicate the correct identification of the surgical site and hence jeopardize the patient's safety.

In such cases, surgeons can greatly benefit from support in spatial orientation. In ENT and skull base surgery, the KARL STORZ optical and electromagnetic navigation systems are excellent tools for this purpose. The position of the instruments is constantly measured either optically, through highly reflective glass spheres on the instruments, or electromagnetically through microcoils integrated in the instrument tip.

Years of experience in instrument making ensures the seamless and ergonomic integration of the navigated instruments into clinical routine.

ENT Navigation Software 5.6.0 with Intraoperative Manual Registration Refinement

ENT Navigation Software 5.6.0 with Intraoperative Manual Registration Refinement

The new software tool for precise navigation

Manual registration refinement following patient registration using landmarks or surface matching can be activated while navigation is in progress. Navigation is thereby not interrupted and the navigated instrument continues to be displayed. Following activation, an additional landmark can be set to adjust the registration accuracy.

Benefits of intraoperative manual registration refinement:

Special Features:

  • Correction of inaccuracy – particularly depth inaccuracy
  • Intraoperative setting and processing of landmarks without interrupting navigation
  • Eliminates the need to set additional landmarks; these can be set intraoperatively at the position of the site where the inaccuracy is identified
  • Possible to reject manual registration refinement at any time without interrupting navigation – navigation can continue with the initial patient registration
