Hemimasticatory spasm probably is the consequence of an abnormal trigeminal hyperexcitability likely induced by the demyelinating lesion of its peripheral motor pathway. The main neurophysiological abnormalities may persist unmodified over a long course of the disease and allow the differential diagnosis of HMS from oromandibular dystonia and temporomandibular dysfunction (TMD).

We report on a patient who presented a transient eyelid motor disorder characterized by bilateral reflex blepharospasm as the main clinical manifestation of a right-sided striatal infarction. This case emphasizes the role of the nondominant striatum in the pathophysiology of eyelid motor abnormalities.
