[Long-term results of surgical therapy of hemifacial spasm and blepharospasm (author's transl)].

Between 1965 and 1976, 95 patients with hemifacial spasm and blepharospasm have been operated according to the method developed by Fisch at the ENT-Clinic of the University of Zurich. 69 of the patients were followed over an interval of 1 to 12 years. 80% of the patients with hemifacial spasm and 65% of the patients with blepharospasm were free of symptoms or significantly improved. These results remained unvaried over an observation period of 6 to 12 years. The motility of the face was preserved to a very high degree in spite of extensive resection of peripheral facial nerve branches.
