Expanded Endoscopic Endonasal Approach

Amin Kassam, Vice President of Neurosciences, explains the Expanded Endoscopic Endonasal Approach.


Let's be honest. Whether your brain tumor is cancerous or benign, having brain surgery is scary.

But thanks to advances in technology and neurosurgical pioneers like Aurora Health Care's Dr. Amin Kassam, more treatment options are available to you than ever before – including a minimally invasive surgical procedure for a wide variety of deep seeded tumors located at the skull base or upper spine.

We call it the Expanded Endoscopic Endonasal Approach.

What is the Expanded Endoscopic Endonasal Approach?

In the past, getting to your brain from the outside-in meant making incisions and removing parts of your face and skull. Not to mention, critical structures like nerves, arteries or parts of the brain itself might have to be manipulated or removed in order to access your tumor.

But a natural opening already exists – your nostrils. They provide a safe pathway to the skull base, as well as the upper portion of the cervical (neck) spine. Plus, using both of your nostrils and sinus cavities not only provides room to insert the endoscope to look inside your skull, but also for specialized instruments for extremely precise treatment of your tumor – while keeping the surrounding structures, nerves and arteries safe.

This means possibly fewer complications, no incisions to your face, and a faster recovery.

What Does the Expanded Endoscopic Endonasal Approach Treat?

  • Pituitary adenomas (acromegaly, Cushing's disease, prolactinomas, non-functional adenomas, pituitary apoplexy)
  • Rathke's cleft cysts
  • Chordomas and Chondrosarcomas
  • Cancers of the Sinus (squamous cell, adenocystic, and metastatic)
  • Other skull base tumors and cysts
  • Brain tumors (craniopharyngiomas, sphenoid sinus carcinomas, olfactory neuroblastomas)
  • Meningiomas of the tuberculum sella, petroclival and cavernous sinus regions

What Are Some Potential Advantages of the Expanded Endoscopic Endonasal Approach?

  • Less pain and risk of scarring because there are no incisions to the face
  • Fewer complications because healthy surrounding brain tissue, nerves and other critical structures are less likely to be disturbed
  • Faster recovery and shorter hospital stays
