Paresis of the facial nerve

Described are symptoms of the supranuclear, nuclear, infranuclear involvement of n. facialis and their different clinical picture. Topognosis, the determination of the level of the lesion, is of prognostic significance in the affection of the nerve. An important contribution to the determination of prognosis in facial paralysis is sound knowledge of the clinical picture and an EMG investigation with electrostimulation of the nerve. Conservative treatment with steroids and antiviral agents is the most effective. Surgical treatment with revision of the nerve in the fallopian canal is left for atypical cases. Dealt with are inflammatory paralyses; Guillain-Barré, Ramsey-Hunt, Banworth’s, and Melkersson-Rosenthal syndromes; paralyses in the pregnant, in diabetics; congenital, traumatic, and tumorous paralyses.
