Advanced imaging technique now developed to enable Neurosurgeons with intra-operative MRI to aid in the removal of complex and hard-to-access brain tumors during surgery.
This new technique relies on a powerful computer system, which assists the surgeon in precisely localizing a lesion, in planning each step of the procedure on the computer screen, and in calculating the ideal access to the tumour before the operation.
This is particularly useful in reaching a tumour located deep inside the brain, areas traditionally considered to be difficult to reach. During the procedure, the computer tracks instrument movement with an extremely high precision, providing the surgeon with total control inside the brain at all times using “real-time” imaging. The surgeon can also check if the tumor has been removed as planned. This improves the outlook for the patient.
Endoscopic removal of tumor through nose (Expanded Endoscopic Trans-Nasal Approach) Endoscpoic neurosurgery involves the insertion of an endoscope, or tiny video camera, through a small incision to treat a range of neurological conditions. The result is
The endoscopic trans-nasal approach is performed through the nostrils. A natural passage way exists at the back end of the nose leading into the sphenoid sinus (an air filled cavity in the depth of the skull), which can be enlarged so that the endoscope and instruments can pass into this air filled cavity. From this region the sella turcica is easily accessed, which is the location of pituitary gland. Neurosurgeons use this route normally to remove the tumor from pituitary (the master glad).
Conventional neurosurgical procedure like conventional craniotomy relies on surgeon’s visualization of the tumour. The surgeon has to spend time and significant effort to find the tumor.
In some types of tumours, surgeons may not completely visualize the tumour and there is a risk that surgeon can resect normal brain tissue along with the tumor, which can result in neurologic deficit, paralysis, loss of speech, blindness etc.
Normal brain tissue can be damaged unnecessarily. This can result in neurologic deficit and prolonged stay in the hospital.
A surgeon performs a subtotal removal of the tumor . The consequence is only partial tumor resection that will result in a faster recurrence of the tumor and neurological symptoms..
The surgeon is guided during the surgery by live Advanced New Generation computer assisted MRI and thus knows exactly where tumor ends and normal brain begins.
Enhanced ability of Neurosurgeon to excise the complete tumor. Less risk of post operative complications. Functional image guidance with MRI allows for accurate, non-invasive preoperative assessment and planning for brain tumor surgery.
MRI guided Brain Tumor Surgery allows a more complete tumor removal with much less risk to surrounding brain tissue.
“Inoperable” tumors (inoperable by conventional surgical techniques) can be resected with MRI Guided Brain Tumor Surgery. Frequently, these are deep seated-relatively benign tumors in children and young adults or elderly patients. Many of these tumors can be cured with this most advanced technology.
“I was looking for a treatment that offered me the best chance for a complete cure,” “But it was extremely important to me to avoid the complications – impotence, incontinence and bowel problems – that commonly result from prostate cancer treatment.” CyberKnife treatment was best option to meet all of those criteria. “What convinced me to do it was the preciseness, how the CyberKnife stops and recalibrates in order to accurately treat the tumor,” I said. “Once I made the decision to go with the CyberKnife, I felt a calm and relief that I wouldn’t have to go through all the complications.
The expect fatigue and some short-term urinary symptoms, The treatment didn’t slow Scott down. Just two days after the treatment ended, he was back out on the golf course, playing 18 holes with his friends. And a few months later he was fly fishing for salmon on Eagle Creek in Labrador on the Atlantic coast of Canada.
The results of CyberKnife treatment exceeded Scott’s expectations. At his last appointment with on November 13, 2006, Scott’s Prostate Specific Antigen (PSA) level was down to 0.7. “Not only did it cure my disease, there were no complications and minimal side effects,”. “I feel very fortunate that I could avoid all the complications that are devastating to men.”
