Electrophysiological studies and tactics of treatment of patients with trigeminal neuralgia
Abstract
Brainstem acoustic evoked potential (BAEP) was examined in 75 patients with trigeminal nerve chronic pain syndrome (TCPS) in course of their treatment. The significant slowing–down of nerve impulse conducting through brainstem structures with the asymmetry at the olivar level due to the increase of between peak intervals on the side of pain has been revealed at 95 % of patients at the clinic entry. Postoperative analysis of BAEP at patients with pain syndrome regression showed the decrease of latencies of V component and between peak interval I–V in comparison with the patients with pain syndrome exacerbation. The received data determine the prognosis of pain syndrome exacerbation during postoperative period; thereat the specific differences between the disease course variants at the stage of postoperative investigation have not been revealed. This fact can explain the effectiveness of use of minimally invasive method of partial radio–frequency destruction of Gasserian ganglion regardless of neuralgia pathogenetical type. Neurophysiology, pathology, diagnostics, management and individual algorithms of patient selection for surgery had been discussed.
