METHOD FOR EARLY PREDICTION OF OUTCOME OF FACIAL NERVE NEUROPATHY IN CHILDREN Russian patent published in 2024 - IPC A61B5/00 A61B8/00 A61N2/00 

FIELD: medicine; neurology.

SUBSTANCE: invention relates to functional diagnostic techniques and can be widely used in clinical practice, in infectious and neurological departments, for early prediction of outcomes of facial nerve neuropathy in children. It involves a clinical neurological examination, electroneuromyography (ENM) with calculating a coefficient of the percentage ratio of the amplitudes of motor responses of the nasal muscle of the affected side to the healthy side. On 4–7th day of the disease, peripheral transcranial magnetic stimulation of the facial nerve is additionally performed on the affected side, the amplitude of the evoked motor response of the nasal muscle is recorded in mV. Then ultrasound examination of facial nerve is performed using high-frequency linear sensor, depth of facial nerve in area of exit from stylomastoid opening is measured in mm. If the ENMG coefficient of the nasal muscle is ≤50% in combination with the amplitude of the evoked motor response of the nasal muscle ≤1 mV and the average depth of the facial nerve ≤7.4 mm, an unfavorable outcome of the disease is predicted, at ENMG-coefficient>50%, amplitude of evoked motor response >1 mV and depth of >7.4 mm—favorable.

EFFECT: method provides more accurate prediction of the outcomes of facial nerve neuropathy already on 4–7th day from the onset of the disease, which will make it possible to carry out timely correction of conducted pathogenetic therapy and reduction of length of hospital treatment.
