Temporary Medial Upper Eyelid Lagophthalmos after External Dacryocystorhinostomy.

Conclusions. Temporary lagophthalmos can occur as a complication of external dacryocystorhinostomy, most likely due to damage of the (only recently described) superficial buccal and/or zygomatic branches of the facial nerve that run upward to cross over the medial ligament and innervate the medial part of the orbicularis oculi muscle.
