Percutaneous thermocoagulation of the Gasserian ganglion allows a good preservation of facial touch sensation with a complete and immediate regression of the symptomatology in a majority of cases. Neurophysiological bases are the peculiar resistance to the thermal lesion of the large myelinated fibers compared to the relatively smaller fibers. The study of the cortical-evoked responses before and after surgery suggests that the afferent volley travels in preference along these large myelinated fibers.
