Motor cortex stimulation as treatment of trigeminal neuropathic pain

Acta Neurochir Suppl (Wien). 1993;58:150-3. doi: 10.1007/978-3-7091-9297-9_34.


A report is given on first experiences with motor cortex stimulation in 10 patients with different forms of neuropathic pain. Three of them had central pain as sequelae of cerebrovascular disease. In none of them did the stimulation provide pain relief. Two patients had pain from peripheral nerve injuries. One did not respond, but the other obtained about 50% pain relief. The remaining 5 patients with trigeminal neuropathy experienced definite pain relief varying between 60 and 90%. During test stimulation most patients had one or two short-lasting generalized seizures. But no one had any motor effects after permanent implantation. Motor cortex stimulation appears to be a new and promising possibility of pain treatment, especially in cases with trigeminal neuropathy, but many problems have yet to be solved, before a clear indication could be given.
