A neurosurgeon in Lafayette, Louisiana, and a graduate of Rush Medical College in Chicago, Dr. Ilyas Munshi has owned a private practice providing neurological diagnosis and surgery since 2001. Dr. Ilyas Munshi devotes his time to brain, spinal, and peripheral nerve conditions, and is well-versed in computer-assisted, image-guided surgery, also called neuronavigation.

Image-guided neuronavigation helps doctors to plan the safest and most efficient approach for a surgical procedure by allowing the surgeon to view the internal area on which he or she is about to operate.

Neuronavigation uses the principle of stereotaxis: generic points, present in every brain, are combined with MRI or CT scan images of the patient’s cranium, offering a personalized view of the brain in question. This technology lets the doctor try out different points of access – to reach a tumor, for instance – before making even a single cut.

Cranial surgery benefits substantially from neuronavigation technology. The ability to plan ahead means the opening that must be made in the skull can be smaller and better placed, for optimal access. Tumors located in important areas of the brain can be removed with considerably less risk of damage to the patient’s motor and mental functions.

Neuronavigation Systems Improve Surgical Accuracy and Patient Recovery

A board certified neurosurgeon in Lafayette, Louisiana, Ilyas Munshi, MD, runs a top-of-the-line neurosurgery facility. Dedicated to using the most advanced tools and methods in neurological surgery, Dr. Ilyas Munshi provides a wide variety of services, including complex spinal surgery, adult and pediatric brain tumor care, and neuronavigation.

Neuronavigation is computer-assisted image-guided surgery that uses brain imaging while surgery is being performed. Through neuronavigation, neurological surgeons are able to accurately determine the target area of the surgery. The method also allows surgeons to see where their instruments are within the brain, lessening the chance of causing damage to healthy areas. Neuronavigation allows for smaller incisions as well, which results in decreased operation time, recovery time, and risk.

A recent study looked at the advantages of using neuronavigation during surgery on spinal and intracranial tumors. Combined with an ultrasound system and CT scanner, intracranial navigation was used, while for the spinal surgeries, a navigation system was combined only with a CT scanner. The results of the study showed that stereotactic tumor biopsies were completed with more than 90 percent accuracy using a neuronavigation system. The study indicated that neuronavigation allows for highly precise spinal and intracranial surgery, while also solving the problem of “brain shift” during procedures.
