Fiagon Navigation System:
Image Guided Sinus Surgery Los Angeles

When certain types of sinus surgery are necessary, the Fiagon Navigation System is a valuable treatment option. This innovative image-guided system provides surgeons with detailed, real-time views of the sinus cavities during sinus procedures. Using the Fiagon system doctors are able to perform safe, through surgeries, operating with the maximum data concerning the unique anatomy of each patient. With the Fiagon system, surgeons can visualize the location of the instrument tip relative to the structure of the patient’s sinuses with extreme precision.

Image-guided surgery with the Fiagon system may be recommended instead of endoscopic sinus surgery for a number of medical conditions, including revision sinus surgery, surgery to correct deformed sinus anatomy, surgery to remove a large number of polyps and surgery to remove damaged tissue in hard to see recesses of the sinuses. The enhanced visualization provided by the Fiagon system assists the surgeon in avoiding nearby anatomical organs and structures, such as the brain, the carotid artery, and the eye sockets. Since preventing injuries to these areas is always of grave concern, this is a great advantage.

Offering the most reliable accuracy of any device of its kind, the Fiagon system has customizable, procedure-specific settings and automated instrument verification. It is useful for everything from the simplest to the most complex types of image-guided sinus surgery.

We proudly serve patients from Santa Monica, Torrance, Los Angeles, and surrounding areas, including Brentwood, Malibu, Culver City, Marina Del Rey, Venice, Pacific Palisades, Manhattan Beach, Redondo Beach, and Palos Verdes.

What is the Fiagon Navigation System?

The Fiagon image-guided surgical navigation system gives us the eyes we need when performing the most thorough and challenging ENT procedures. Fiagon provides real-time views of the location of the instruments we are using, as well as the critical structures such as the carotid artery and the optic nerve. At the Daneshrad Clinic, we feel the Fiagon Navigation System gives Dr. Daneshrad the maximum data he needs about the unique anatomy of the sinuses of every patient. This navigation system allows image-guided surgery that elevates the safety and effectiveness of every procedure. It gives us the option of using less invasive approaches during these procedures, resulting in less pain and quicker recoveries for our patients.

How does the Fiagon Navigation System work?

The Fiagon system uses electromagnetic matrix tracking through sensors that are embedded in the top of various instruments, called FlexPointer instruments. The instrument sensor works together with the sensor embedded in the headrest. This allows triangulation and the Fiagon system can then identify the exact position and orientation of the tool. The system features ENT specific software and a proprietary algorithm to localize the instrument and transmit its precise position to the endoscope or microscope Dr. Daneshrad is using for the surgery.

The heart of the Fiagon Navigation System is the FlexPointer with the embedded sensor. The tip of the FlexPointer can be adjusted during surgery by bending, allowing it to make its way through the tightest sinus cavity. The system can use computerized tomography (CT) or magnetic resonance imaging (MRI) images to plan the surgery, as well as record video sequences and pictures during the procedure.

Where is the Fiagon Navigation System used?

The Fiagon Navigation System is designed to support conventional ENT navigated surgery, including adenoid removal, frontal sinusotomy, operations involving unconventional sinus anatomy, partial removal of the orbital lamina, and resections in the ethmoid and sphenoid bone.

The American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) endorses the use of image-guided surgery, as provided by our Fiagon Navigation System, for procedures to treat conditions such as the following (excuse the technical language):

  • Revision sinus surgery
  • Distorted sinus anatomy
  • Extensive sino-nasal polyposis
  • Pathology involving the frontal, posterior ethmoid, and sphenoid sinus
  • Disease abutting the skull base, orbit, optic nerve, or carotid artery
  • CSF rhinorrhea or conditions involving a skull defect
  • Benign and malignant sino-nasal neoplasms

Am I a candidate for surgery using the Fiagon system?

Any procedure we perform that can benefit from increased interior visualization is perfect for the Fiagon Navigational System. Dr. Daneshrad believes this advanced equipment sets our clinic apart from other ENT practices.

What are the benefits for patients of the Fiagon Navigation System?

The dangers posed by sinus surgery often come in the possibility of contacting nearby anatomical organs and structures, such as the brain, the carotid artery, the optic nerve, and the eye sockets. The Fiagon Navigation System provides such detailed imagery that avoiding these structures becomes that much easier. This increases safety for our patients.

This system allows Dr. Daneshrad to create a 3D map of the operation area through the use of CT or MRI imagery. This happens before the surgery begins. In effect, it gives Dr. Daneshrad a 3D map of the inside of the patient’s head.

Because this system gives Dr. Daneshrad the most reliable accuracy and visuals available in the ENT world, Fiagon enables us to use less invasive methods, where possible. This results in less post-surgical pain for our Daneshrad Clinic patients and quicker recovery times.

Is the Fiagon system safe?

The Fiagon uses electromagnetic energy to generate the images, working through the sensors in the FlexPointer instrument and in the headrest behind the patient’s head. This energy is used throughout medicine and is safe and effective for imaging.

The Fiagon system is not only safe, but it makes Dr. Daneshrad’s surgeries safer, thanks to the accuracy it provides. By increasing visualization inside the patient’s head, Fiagon improves our outcomes.

Are there any risks associated with the Fiagon Navigation System?

This system doesn’t involve any specific risks unto it. Of course, there are risks with any sinus surgery, but those are not due to the Fiagon system as mentioned above, this system lowers the risks associated with these intricate surgeries.
