  • Title: [Clinical-electroneuromyographical characteristics of facial nerve paralysis in children].

    Abstract:
    A clinical-electroneuromyographical study of 40 children (32 (80%) of them aged from 12 to 17 years, mean age 13,9+/-1,8 years, and 8 (20%) - from 1 to 8 years, mean age 4,4+/-2,1 years) were studied in the acute period of facial nerve paralysis (FNP). Six (15%) children had FNP in the anamnesis. Among precipitating factors were the cold exposure the day before disease onset (20 (50%) patients), symptoms of flu (13 (32,5%) patients) and psycho-emotional tension (3 (7,5%) patients). No precipitation was noted in 4 (10%) children. The degree of muscle paresis was 81,9+/-7% that corresponded to clinical stages III-IV according to K. Rosler. An electroneuromyographical analysis of motor ortho- and antidromic response to the facial nerve stimulation on the side of paresis and on the contralateral side in patients and controls revealed the presence of proximal axon- and myelinopathy of facial nerve with the involvement of its own motorneurons and brain stem interneurons. The maintenance of wink reflex and F-wave blocks in the period over 3 weeks are prognostically unfavorable factors for restoration of mimic muscle function in the early stage of disease.
