Endoscopic Skull Base Surgery for Head and Neck Cancer

It can be frightening to learn that there's a tumor in a difficult-to-reach area such as your skull base. When you come to Cedars-Sinai, you have access to treatment options that are not widely available. We are among the few programs in the L.A. area offering endoscopic skull base surgery. Our team successfully removes tumors that were previously considered inoperable.

What Is Endoscopic Skull Base Surgery?

Your skull base includes the bottom of your head and the bony surfaces behind your eyes and nose. Just beyond the skull base is a complex network of soft tissue, nerves and cartilage that makes accessing tumors challenging.

Endoscopic skull base surgery allows surgeons to safely navigate this area using thin instruments along with a light and camera. We pass these instruments through the openings of your nostrils:

  • The light and camera provide real-time, high-resolution views of the tumor and nearby structures.
  • Sophisticated tools at the tip of the instrument allow surgeons to safely remove tumors.
