Designed for Better Access.
Better Procedures.
Better Patient Care.

The SPIWAY® Endonasal Access Guide (EAG) platform is the first and only access technology for endoscopic endonasal skull base surgery. The SPIWAY EAG platform protects the surgical corridor and is proven to improve visualization by significantly reducing lens obscurations and cleaning events during your procedures1.

Help reduce trauma from 100+ blind passes of instruments/hour2

Reduction in endoscope obscuration time*

Less endoscope cleaning actions per minute using the SPIWAY EAG platform*

The SPIWAY EAG Platform Difference

The SPIWAY EAG platform was created with the same goal as the endoscopic endonasal approach: improve visualization of critical structures.
