The records of 379 patients seen by us have been reviewed; of these, 102, or 28% had hemifacial spasm (HFS). HFS has features common to postparalytic synkinesis and provides much useful information on the nature of misdirection phenomena. It is the purpose of this paper to elaborate on the details of the symptoms and to provide the basis for thorough understanding of the facial nerve.HFS was 2.8 times as common in females as in males, thus confirming other authors' opinion that the incidence is higher in females. The age of the onset of the spasm and the first clinical visit was after 20 years of age, showing the disorder as being predominant in adult life. The lower lid was involved first in all patient. The spasm spread down to the face rapidly in most cases within 2 years, although there have been contrary opinions in slow progression. Emotional stress and movement of the facial muscles played a definitive role in precipitating spasms. These revealed that psychological factors and positive feedback played a significant role.Theories on the etiology of the HFS were reviewed. This paper focused attention on ephaptic transmission. We predict that fiber interaction will be an inportant topic in the field of facial nerve research.
