Surgical treatment of dystonia has experienced a tremendous change over the past decade. Whilst selective peripheral denervation is reserved for cervical dystonia refractory to botulinum toxin injections, deep brain stimulation (DBS) of the pallidum has gained a wide scope and presents an elementary column in the treatment of medically refractory patients, nowadays. There is consensus that idiopathic generalized, cervical and segmental dystonia are good indications for DBS, although there is still a paucity of studies providing high-level data according to EBM criteria. Efficacy is maintained on longterm. Several other forms of primary dystonia are still under investigation but it appears that patients with Meige syndrome and myoclonus-dystonia gain also marked benefit. Study of the outcome in secondary dystonia disorders is more complex, in general, but patients with tardive dystonia gain similar improvement than patients with idiopathic dystonia. Overall, the risk profile of pallidal DBS is quite low, and it has been shown to be cognitively safe. The effect of pallidal DBS on non-dystonic extremities has not received much attention, albeit there are hints for a pro-akinetic mechanism. Several questions remain to be solved including optimal programming of stimulation settings, battery drain with high stimulation energies and the elucidation of the mechanisms of DBS in dystonia.
