Technology Leads the Way to Accurate Surgeries

OTO Experience Thought Leaders Series: Frontal Sinus Course: Maximize Clinical Outcomes with Planning Software and Augmented Reality — Hosted by Stryker

Wednesday, September 23

6:00 pm – 7:00 pm (ET)


Marc A. Tewfik, MD

No longer for the gaming environment only, augmented reality is finding a new home in the surgical suite. Together with planning software, these high-tech systems can help surgeons perform frontal sinus procedures in an efficient, accurate, and reliable manner.

It all begins with surgical planning software. Today’s software tailored to each patient’s unique anatomical structure, enables surgeons to identify the fronto-ethmoidal cells that affect the frontal sinus drainage pathway, as well as the pathway itself. “This allows for a better 3D understanding of the frontal recess anatomy of each individual patient,” said Marc A. Tewfik, MD, associate professor of otolaryngology – head & neck surgery at the McGill University Health Centre in Montreal, Quebec, Canada. “It provides the surgeon with the ability to create a surgical plan ahead of time, based on that patient’s specific anatomy,” he continued. “By knowing where the drainage pathway is located, the surgeon can accurately cannulate and open up the frontal sinus in a safe and effective fashion.”

Then augmented reality comes in. While augmented reality has been used in surgeries for a few years now, Stryker is introducing a platform where information gathered through the surgical planning software is displayed on a flatscreen monitor overlaying the live image captured during surgery. This can be used during endoscopic sinus surgery, skull base surgery, and even routine sinoscopy. “This allows for seamless integration of navigation technology with endoscopy equipment,” Dr. Tewfik said.

When the information collected by the software is displayed on the screen, surgeons can see real-time positions of surgical pathways during a procedure. The augmented reality system then helps them guide their tools where they need to be to cannulate the frontal sinus. The system can also accentuate critical structures—including the optic nerves, carotid arteries, the skull base, and orbital walls—on the screen. This makes it possible for surgeons to safely work around these structures. If so desired in the event an instrument does get too close to one of them, a proximity alarm will sound.

This session will be based on case studies and will cover frontal anatomy in depth, review the International Frontal Sinus Anatomy Classification naming methodology, and demonstrate how these two technologies are complementing each other to make frontal sinus procedures better for all.
