Treatment of Brain Tumor | Cranial Surgery Procedures

Computers, computer navigation and special intraoperative equipment and monitors have allowed us to bring the 21st century into the OR. No longer should neurosurgery be performed using only the surgeons judgment as to determining routes through the brain, skull openings etc.

Dr. Duma has written book chapters on the use of “navigation” through the brain intraoperatively and has been an instructor of this topic at major national neurosurgical conferences for years.

Brain Cranial Procedures

The surgeon is able to register points from the patient’s head into the computer so that the computer can guide him or her to a tumor through an MRI map of the brain.

The concept is as follows: if a patient undergoes an MRI prior to surgery, that MRI may be used in the operating room literally to guide the surgeon through the brain DURING the operation. Small markers, or fiducials, are attached to the patients scalp prior to the MRI with adhesive and these are picked up by the MRI. Once the patient is positioned in the OR, these fiducials are registered into the computer and the patient’s brain is now part of the three-dimensional space within the OR. Using a hand-held probe, or the actual operating microscope itself, the surgeon can navigate through the brain to reach the desired target with precision, efficiency and the utmost of safety. At the conclusion of the cranial surgery procedures the adhesive markers are removed and the patient is returned to the recovery room for a faster recovery. The modern neurosurgical patient should insist on this technology as being a part of his or her OR experience.
