Herein, we describe a novel manifestation of facial nerve synkinesis, swallow-induced eyelid myokymia, and hypothesise that this phenomenon is due to synkinetic facial nerve innervations of the stylohyoid-posterior digastric complex of suprahyoid muscles and orbicularis oculi muscle. In our patient's case, onabotulinum toxin A treatment provided good therapeutic response. Swallowinduced eyelid myokymia is a unique and previously unreported variety of facial nerve synkinesis.
