Our objective is to optimize diagnosis of neurotrauma during CFT. Methods: We examined 108 patients, 33,4 ± 0,9 years old (95 men, 13 women), in the acute phase of CFT with damage to the middle and lower parts of the face. The control group consisted of 30 healthy volunteers. Results: We studied the evoked visual potentials in patients with CFT in the acute phase, where latent period of the peak P100 reached 122,4±1,12ms from the left and significantly (p < 0,05) higher to the control group (106,3 ± 1,68 ms, left). The amplitude of the P100 wave in the acute phase was reduced (3,2 ± 1,32μV), which was significantly (p < 0.01) lower to the control group (8,9 ± 0,82μV). Subsequently, it was noted that the wave amplitude in the recovery period was similar to the control group. Analysis of the cognitive P300 wave was characterized by an increase in the latent period (324,6 ± 2,89ms) and was significantly different from the control group (303,9 ± 1,47ms). The amplitude of the P300 wave was 4,55 ± 0,87μV while the control group 7,39 ± 0,58μV. Conclusion: This study allows us to make an objective assessment of cerebral dysfunction in CFT, clinical manifestation of which is often offset by the severity and the stress state with a primary lesion of the bones of the maxillofacial skeleton.
