The imaging showed a large mass compressing the brain on the right side, thus impacting the left side of the body,explained Yasu Harasaki, M.D., neurosurgeon, Genesis Neurosurgery Group. It measured about 2 inches in diameter; and though 2 inches doesn't sound that big, when its pressing on your brain, that's actually a very large mass."
The diagnosis rightfully stunned Mary, but she quickly found consolation in her neurosurgeon.
When you hear brain tumor you think, "I'm going to die, but I didn't think that because Dr. Harasaki explained things so well from start to finish," Mary said. "He kept me calm."
Dr. Harasaki's calming presence comes from specialized experience and training in neurosurgery. Dr. Harasaki joined Genesis in May 2019. His training includes an internship and residency at the University of Colorado Health Sciences Center. He combines his intensive training in neuro and spine surgeries with the innovative equipment at Genesis to provide expert care right in Zanesville.
Detaching, removing and patching a meningioma tumor
Dr. Harasaki could tell from Mary's initial imaging that the tumor was likely a meningioma, an extremely slow-growing tumor that develops on the delicate membrane covering the brain. Thankfully, 90% of meningiomas are not cancerous.
To remove Mary's benign and enlarged tumor, Dr. Harasaki used cutting-edge technology, including a stereotactic navigation system (it's like a GPS for the brain) and the new ORBEYE 4K-3D microscope at Genesis during the intricate surgery. Genesis is the first healthcare system in Ohio to have this emerging technology.
With the finest available tools and a highly trained team of specialists, Mary's brain tumor removal surgery was completed with precision and accuracy. In addition to detaching the tumor from the membrane, Dr. Harasaki removed the section of membrane the tumor grew on, as well as the diseased membrane growing around the tumor. Then, he patched the membrane using a sheet of material made of collagen.
