Facial myokymia: a clinicopathological study

Facial myokymia.

The facial musculature may be the site of a great variety of involuntary movements, often of doubtful nature and obscure causation. One form was sharply delineated both by clinical description and probable pathogenesis by Andermann, Cosgrove, LloydSmith, Gloor, and McNaughton (1961). These authors drew attention to the condition of facial myokymia of which they described four cases of their own...

Facial myokymia in the Guillain-Barré syndrome.

Facial myokymia, a unique involuntary movement of facial muscles, is described in a patient with Guillain-Barré syndrome. Although this involuntary movement is most often described with intramedullary lesions of the brain stem, it may also appear with lesions external to the neuraxis. We review the literature and propose a more widespread distribution of potential lesions along the facial nerve...

Facial myokymia in multiple system atrophy.

Two patients are described with clinical and neuroimaging features consistent with a diagnosis of multiple system atrophy (MSA). The patients are unusual in that facial myokymia became apparent clinically at some stage in their illness. In each patient, the nature and severity of the involuntary facial movements evolved over the course of the illness. Electrophysiologically the movement pattern...

Facial myokymia: a clue to the diagnosis of multiple sclerosis.

Introduction Facial myokymia is an unusual form of involuntary movement of the facial musculature which is characterized by spontaneous undulating waves of contracting muscle fibres spreading across the face. In a recent review, Gutman, Thompson & Martin (1969) were able to find forty cases reported in the world literature and added two of their own. Of these cases, in twenty-three the diagnosi...
