[Value of the study of trigeminal nerve evoked potentials in chronic trichloroethylene poisoning. Preliminary results].

Abstract

Results of a study concerning the trigeminal nerve impairment as the one caused by trichlorethylene chronic intoxication by somatosensory evoked potential reveal three kinds of anomalies: increase of the stimulation voltage, excessive latency delay with morphological anomalies and excessive graph amplitude. These anomalies confirm clinical disturbance (hypoesthesia in the trigeminal area) and open a debate about the real mechanism of the trichlorethylene neurotoxicity.
