The minimally invasive endoscopic endonasal approach for skull base surgery is an innovative technique yet procedural challenges persist

The SPIWAY® EAG platform is clinically proven to improve visualization and reduce inefficiencies during your procedures4*

55% Reduction in endoscope obscuration time

Endoscope Obscuration Time

31% Less endoscope cleaning actions per minute

Endoscope Cleaning Actions

“This technology may offer a greater time-saving impact with patients undergoing long EEA operations, with potentially less interruption and frustration for the surgeons.”
