[Somatosensory evoked potentials in patients with lesions of the trigeminal nerve system].

These are results of comparison of clinical data and parameters of early components of somatosensory evoked potentials (SSEP) in patients with various pathological disorders in the trigeminal nerve system. The investigations evidenced that neurologic patients have different degrees of disorders in structural-functional organization of trigeminal nerve system resulting from the disease itself and previous therapeutic interventions. Some of the peculiarities of SSEP changes, e.g., their amplitude and/or temporal asymmetry under stimulation of the sites of intact and afflicted sides of the face are believed to correspond to pathological changes in trigeminal nerve system. These features can serve as diagnostic and prognostic tests.
