Abstract

In October 1965, W. H. Sweet, introduced the particularly valuable technique of electrocoagulation of the trigeminal ganglion in the neurosurgical treatment of trigeminal neuralgia6. Assuming that the less myelinated small pain fibers (A delta and C) are more sensitive to the heat transmitted through an electrode than the heavily myelinated A-beta touch fibers, graduated controlled thermocoagulation could produce differential destruction of pain fibers7. A large experience obtained in 353 such procedures up to 19748 and the results of other groups9 including our own4, 5 confirm the hypothesis. Experimental neurophysiological studies seem also to support this assumption1, 2, but anatomopathological correlations still fail to do so.
