Researchers have devised a noninvasive method of removing defective brain circuitry which could allow doctors to cure painful neurological illnesses without resorting to traditional brain surgery.
Brain Surgery Without A Scalpel Developed By A Research Team
Tumors, blood clots, aneurysms, epilepsy, and Parkinson’s disease are among the disorders for which brain surgery is utilized. A neurosurgeon carries it out with the assistance of a medical anesthesiologist who is well-versed in the forms of anesthetic monitoring and post-operative care required for such delicate procedures.
The brain is known as the most complicated organ in the human body. It controls motor functions and operation of other organs, but there is not much information available with the medical science also how it operates.
In research, a team has found a method where surgery of the brain can be carried out without using a scalpel also. In neurology, this is a breakthrough; the surgeries are done with operative methods only where experts need to carry out a surgical process where cuts and scars are considered normal.
In some situations, this medical anesthesiologist may be a neuroanesthesiologist with advanced clinical training in anesthesia for brain and spinal procedures. These are some of the most common procedures that involve the brain or its surrounding areas. The National Cancer Institute provided some of the information used in the explanations below.
“This novel surgical strategy has the potential to supplant existing neurosurgical procedures used for the treatment of neurological disorders that don’t respond to medication,” said researcher Kevin S. Lee of the Departments of Neuroscience and Neurosurgery as well as the BIG Center for Brain Immunology and Glia. “This unique approach eliminates the diseased brain cells, spares adjacent healthy cells and achieves these outcomes without even having to cut into the scalp.”
After imaging has revealed a probable problem, biopsies are usually performed. To take brain cells or tissue for pathological evaluation, the surgeon creates an incision in the skull or inserts a needle.
An implantable pulse generator is a battery-operated medical device that delivers electrical stimulation to particular parts of the brain. The most common indications for DBS include movement disorders such as Parkinson’s disease.
Another benefit of this approach’s precision is that it can be utilized on irregularly shaped targets in locations where normal brain surgery would be exceedingly difficult or impossible to reach.
“The researchers write in their new paper” “The noninvasive nature and specificity of the procedure could positively influence both physician referrals for and patient confidence in surgery for medically intractable neurological disorders,” the researchers write in their new study.
A narrow tube called an endoscope is threaded through the mouth, nose or small incisions in the skull to access or remove brain tissue in this minimally invasive procedure.
The endoscope is equipped with a light, and a camera and the operation is carried out using tools inserted through the endoscope. One type of neuro-endoscopy is endoscopic transsphenoidal surgery (also known as endoscopic pituitary surgery).
The endoscope is threaded through the nose to remove brain tumors and lesions around the pituitary gland, which is located directly behind the bridge of the nose.
The cerebellum and brainstem are two areas of the brain that are treated in this way. For example, to cure a Chiari malformation, the surgeon makes an incision in the back of the patient’s head and removes a little piece of bone from the bottom of the skull. This procedure frees up room for the cerebellum and decreases spinal cord pressure.
Clinical studies are currently being conducted to find better ways to reduce the symptoms and side effects of current brain tumor treatments to improve patient comfort and quality of life.
