Marcus Gunn jaw winking with trigemino-oculomotor synkinesis of the inferior division of the oculomotor nerve

Iris S Kassem et al. J AAPOS. 2009 Jun.

Abstract

Synkinetic aberrant innervation syndromes can involve abnormal movements of multiple extraocular and eyelid muscles. The authors describe a case of eyelid elevation associated with simultaneous adduction and depression of the eye upon chewing, sucking on a bottle, or wide opening of the mouth since birth. This represents a unique case of congenital Marcus Gunn jaw winking with trigemino-oculomotor synkinesis involving the inferior branch of the oculomotor nerve. The most likely explanation for these abnormal movements is prenatal aberrant innervation of eyelid and extraocular muscles.
