Intraoperative Neurological Monitoring in Brain Tumor Surgery

"A few months ago, my left calf started moving on its own, uncontrollably. It would take minutes to stop. Doctor, is this related?"

Mr. Tsai's symptoms might be indicative of epileptic seizures. The human brain, composed of billions of neurons forming a complex network, operates like a sophisticated computer, requiring smooth pathways for thought processes and voluntary limb movement. When neurons discharge unexpectedly, it can lead to involuntary spasms of the limbs or even temporary loss of consciousness, a condition known as epilepsy. Brain tumor cells can encroach on the space of healthy cells, disrupting, and even taking over the functions of normal neurons, leading to symptoms. After undergoing an MRI scan, it was confirmed that Mr. Tsai had a tumor on the right side of his brain, located near the motor cortex responsible for limb movement. Craniotomy to remove the tumor could relieve the surrounding healthy brain tissue from pressure, alleviating symptoms.

Brain tumor cells and normal neurons often coexist in the same space. With the aid of a microscope, experienced surgeons can distinguish abnormal tumor cells. Their knowledge of brain anatomy allows them to ascertain the relative position of Mr. Tsai's tumor to the motor cortex. Utilizing "intraoperative neurological monitoring" technology, surgeons can assess the risk of postoperative paralysis caused by tumor removal. This enables them to remove the tumor to the greatest extent possible without incurring collateral damage. Post-surgery, Mr. Tsai's seizures were controlled, and he regained the ability to move freely, continuing his treatment for the brain tumor.

When intracranial tumors are located near critical structures like the motor cortex, language areas, and facial nerves, "intraoperative neurological monitoring" allows surgeons to remove as much of the tumor as possible without compromising the patient's vital functions. This innovative approach offers hope and a pathway to recovery for individuals looking for a cancer center that employs cutting-edge techniques in the battle against brain tumors.
