Abstract
A case of Maria Amat's phenomenon was presented. A 75 year old man had right facial palsy of ten year's duration. Functional recovery had been almost complete, but there were associated movements among the facial muscles.
He showed contraction of the right orbicularis oculi muscle synchronizing with the facial muscle contraction. Electromyographic study showed that abnormal facial synkinesia was an intrafacial associated movement.
As a similar synkinesia is caused by paradoxical levator inhibition, it is very important to do electromyographic study for exact differential diagnosis. A 75 year old man proved to be Mann Amat's pheno menon with electromyographic evidence.
