Surgery for Parkinson's has advanced in recent years; in fact the technology used in the 90s is far from what we do today.

The main improvement lies in the planning systems before surgery, new neuro-navigators have helped locate the areas of the sub-thalamus in a more accurate and faster manner, without a doubt the improvement of the quality of magnetic resonance images of the brain, then the intra-cerebral electro-physiological registration systems.

Moreover stereotaxic guides have favourably influenced effectiveness and less surgical time, which results in fewer post-operative complications. Fewer days of hospitalization with an average of 4 days in the hospital and very few complications, barely 1%, as an immediate complication has been drowsiness and slight mental depression.

In turn new stimulator implantations (stimulators, pacemakers) have come out which are currently much smaller, 4-5 times smaller than in the past. They also allow for the electrophysiological programming to be of better quality and more efficient. In addition, it will allow us in the near future to have the patient help the programming through inputs. We will also have a rechargeable system which will last more years with the same stimulator or battery and allow fewer replacements.
