Most patients were kept awake during the surgery to help surgeons correctly guide in the electrodes.
Being awake while a surgeon drills into the skull was frightening prospect for many patients so many did not proceed with the treatment.
Now neurosurgeon Girish Nair is leading a team at the Royal Melbourne that is using the new technique.
Replacing the bulky frame is a more petite 3D printed piece of equipment. Before surgery the frame is custom-made to fit the patient’s head.
This means the patient can be moved, pre-operative scanning is much faster, and surgeons can target specific areas of the brain with sub-millimetre precision.
“The patient comes to theatre, the custom-made implant is attached to the skull, and we are off and racing,” Mr Nair said.
Importantly the patient is totally sedated during the brain surgery.
Mr Nair approached Mr Al-Sarouny to see if he would be willing to undergo the new surgical technique. He underwent DBS last week and the results have been near miraculous.
Mr Al-Sarouny tremors have virtually ceased for now and he is able to move without shaking – albeit slowly.
“I felt like power was returning to my brain,” he told 9News.
“It was like a dream come true.”
Deep brain stimulation is not a cure for Parkinson’s, but the positive physical improvements are predicted to last for up to a decade.
Mr Al-Sarouny is grateful for every second of “normal” movement.
“I want to work. That’s the first thing. I want to go back to my life.”
