North Shore-LIJ Neurosurgeon is 1st on Long Island to Use 3-D Endoscope for Pituitary Tumor Removal

NEW HYDE PARK, NY – The Skull Base Center at Noth Shore-LIJ's Cushing Neuroscience Institute (CNI) is the first center on Long Island to use the Visionsense VSII three-dimensional (3D) endoscope camera system to remove a pituitary tumor in 61-year-old Eileen Koslowsky from Flushing, NY.

“We have been doing minimally invasive endoscopic skull base tumor removals through the nose for many years,” said Mark B. Eisenberg, MD, CNI’s neurosurgeon and director of the Skull Base Center, who performed the surgery on Nov. 8 at Long Island Jewish (LIJ) Medical Center in New Hyde Park, NY., with endoscopic sinus surgeon B. Todd Schaeffer, MD.  “However, the new Visionsense 3D endoscope allows us to precisely locate the tumor and see it much more clearly in 3D so that it can be removed more completely and safely.”

Traditional endoscopes only provide a 2D image on the viewing screen just like a regular television.  The Visionsense technology is the only 3D stereoscopic endoscope. The 3D camera sensor is a microchip located at the distal end of the endoscope, millimeters from where the surgery is happening. 

With the Visionsense VSII 3D miniature camera system, the surgical team wears special 3D glasses, such as those used to view 3D movies in theaters.  Dr. Eisenberg and Dr. Schaeffer view the surgical field on a monitor next to the operating table.  This allows them to see the brain and nearby critical structures in 3D with true depth perception. 

“As opposed to looking at a flat image of the brain and surgical field, the 3D endoscope allows us to actually see a life like image of the brain itself,” said Dr. Eisenberg.  “Patients are able to recover much more quickly and resume their daily activities.”

About CNI’s Skull Base Center:

CNI’s Skull Base Center consists of a select, multidisciplinary team of neurosurgeons and related specialists that are experienced in the diagnosis of skull base disorders and the intricate techniques of skull base surgery. Thanks to advances in diagnostics and surgical procedures, once-untreatable skull base tumors and other disorders can now be treated successfully.

The Skull Base Center provides world-class expertise in a field of neurosurgery that combines well-established techniques of micro neurosurgery with newer, less invasive techniques to more safely remove tumors and treat vascular problems of the skull base, pituitary fossa (where the pituitary gland resides), and cavernous sinus (a cavity at the base of the brain).  The Center is comprised of a distinguished, multidisciplinary team of board-certified skull base neurosurgeons, otolaryngologists, head and neck surgeons, neuroradiologists, interventional neuroradiologists, anesthesiologists, nurses, physician assistants and physical therapists. Each team member is dedicated to delivering the highest quality of care to patients with meningiomas, pituitary tumors, vestibular schwannomas/acoustic neuromas, disorders of the cavernous sinus and facial pain.
