StealthStation S7 frameless brain stereotactic navigation system.New York Harbor Healthcare System has just purchased a StealthStation S7 frameless brain stereotactic navigation system and it is already in use (March 1) for brain and skull base surgery. This technology is particularly used to plan and perform surgery for removal and biopsy of brain and skull base tumors, although it will also be used for other neurosurgical and otolaryngological procedures.

It allows the surgeon to perform image-guided brain and skull base surgery using a computer to help determine the shortest and safest was to resection. Detailed pictures of blood vessels and nerve roots are seen with a clarity not possible with earlier technologies. Because it does not require attachment of bulky frames to the head, the Stealth S7 allows for safer biopsy of tumors in patients that are wide awake.

According to Dr. Samadani, one of the Manhattan VA neurosurgeons, the technology essentially follows the same principles as the GPS in your car, or the Wii video game system but is orders of magnitude more accurate and sensitive to changes in movement. The patient’s CT or MRI scans are downloaded into a computer to generate a 3-D model of the patient’s head. The surgeon then fixes a reference point on the patient’s skull that is seen by a camera at the foot of the operating room table. The movement of specific surgical instruments relative to the reference point is detected by the camera. The surgeon then knows precisely where the tip of their instrument is in all three-dimensions, relative to adjacent structures in the brain or skull. The technology can even be used with the microscope for sub-millimeter accuracy and with the endoscope to resect tumors through the nose. It is also helpful to confirm margins at the end of a tumor resection.

“While no technology can replace good judgment, the Stealth S7 is still a very powerful surgical tool for both neurosurgery and otolaryngology” said Dr. Samadani. “It helps us know very precisely where we are in three dimensions which enables smaller incisions, better ability to protect surrounding vital structures, faster surgeries and less recovery time. We will be able to perform stereotactic procedures with comfortable awake patients.”

Dr. Samadani said that using Stealth technology to remove tumors deep in the brain offers patients the care they deserve, and the best of contemporary science. Stanley Read, RN PCTC/OR said that over the past five years Stealth Technology has been leased for specific procedures, but having it available at all times is a tremendous advantage for patients. Chief of Staff Dr. Michael Simberkoff , said, ”We are committed to providing Veterans with the best care anywhere, In neurosurgery having this technology in the hands of outstanding surgeons like Dr. Samadani shows we really mean what we say.”
