NaviENT guides surgical interventions where the surgical instrument enters the patient’s head through the nose. It shows the location of the tip of the instrument relative to surrounding anatomy, as imaged in a pre-surgical CT scan of the patient. This enables ENT surgeons (otolaryngologists) to make better informed decisions during functional endoscopic sinus surgery (FESS) and skull base surgeries.
Easy Integration into the OR
Compact and Flexible
NaviENT’s light, compact and foldable cart takes up minimum space in the operating room or in the office and can be easily positioned next to an endoscope cart. The system can be carried into any OR and can be prepared for use in minutes, even in the middle of surgery. Its long boom arm allows the display to be placed conveniently next to the endoscope monitor.
Quick and Easy Set up
NaviENT is designed for convenient routine use. Its set up process is quick and easy. There are no cables to connect, no spherical optical targets to mount, no head straps to wrap and no field generator to place near or below the patient’s head.
Streamlined User Interface
NaviENT’s user interface is streamlined and simple to learn. Its step-by-step workflow is easy to follow. Its gesture based features enable the surgeon to control the system during surgery with no assistance.
NaviENT uses an innovative registration method which is accurate, reliable, and fast. The registration process takes less than a minute to complete.
NaviENT optical tracking system is known for its exceptional and robust accuracy. Unlike electromagnetic sensors, it does not require wired sensors and is not affected by the presence of metallic objects and electromagnetic fields in the environment.
NaviENT’s software user interface is designed to be intuitive and simple to follow. The patient data browser lists all the patient scans found in the NaviENT local repository and allows the importing of new DICOM data from a CD/DVD, USB or network drive. Once data is loaded, NaviENT software operation proceeds sequentially through 5 stages as follows:
This stage displays the 3D dataset as well as 2D axial, coronal and sagittal reformatted slice views and allows the user to rotate, zoom and explore the data.
A. Check tracking system
B. Verify patient info
C. Control patient image opacity and contrast
D. Rotate, zoom, pan and scroll between images.
2 Mark Landmarks
This stage walks the user through selecting a few anatomical landmarks on the 3D scan. The names of each landmark and an illustration of its approximate locations are displayed for convenience.
3 Set Up
This stage provides step by step instructions to place the patient tracker and position the tracking device. The live video stream displayed on the side panel makes it very intuitive to position the camera.
A. Verify detection of the patient tracker
B. Verify if the tracking device is positioned optimally
C. Verify the calibration of each instrument’s tip.
NaviENT uses landmark based registration followed by innovative trace based registration. This stage provides step by step instructions to perform the registration process.
Presents the real-time location of the instrument tip super imposed on the 2D images of the sagittal, axial and coronal views of the patient scan.
• Smart Zoom automatically zooms onto the navigation area
• Visual verification of the navigation accuracy
• UI control by gesture commands
- Registration pointer
- Bayonet pointer
- Maxillary ostium seeker
- Frontal ostium seeker
All instruments have permanent markers and are steam sterilizable. Unlike retro-reflective spherical markers their accuracy do not degrade by partial occlusion, solided targets or spurious light reflections.
- Reusable peel & stick patient tracker
- Universal Tag adaptor clamps easily to any surgical instrument like shaver or suction
- Calibrator instrument calibrates the tip of instruments in a few sections
- Verify instrument tip accuracy in the zoom window.
Benefits of Optical Tracking System
Optical tracking systems are superior and preferred over electro-magnetic systems for
the following reasons:
- Greater accuracy
- Better reliability
- No interference from ferromagnetic metals in the OR/OT
- No wire connection between the instruments and console
- Simpler and more user friendly
- Convenient to use

Benefits of Image-guided Surgery
Study shows that IGS would allow more complete dissection, obviating the need for revision surgery. It is safer for patients and causes fewer complications.
Image-guided surgery has become an industry standard for many endoscopic sinus surgeries. The American Academy of Otolargyngology – Head and Neck Surgery (AAO-HNS) endorses the use of image-guided surgery for procedures including *:
- Revision sinus surgery
- Distorted sinus anatomy of development, postoperative, or traumatic origin
- Extensive sino-nasal polyposis
- Pathology involving the frontal, posterior ethmoid and sphenoid sinuses
- Disease abutting the skull base, orbit, optic nerve, or carotid artery
- CSF rhinorrhea or conditions where there is skull base defect
- Benign and malignant sino-nasal neoplasm
