local.description.resumoBackground. Report of three cases of medial upper eyelid lagophthalmos as complication of external dacryocystorhinostomy.History and Signs. Shortly after dacryocystorhinostomy (skin incision on the side of the nose), three of ten consecutive patients (28 ± 4 years; mean ± standard deviation), presented with anipsilateral lagophthalmos of 4 ± 1 mm in voluntary eyelid closure and 6 ± 1 mm in spontaneous blink. The lagophthalmos was due to a selective paresis of the medial part of the orbicularis oculimuscle of the upper eyelid. Patient 1 complainedbitterly of dry eye symptoms and of her lagophthalmos. Patient 2 had mild symptoms but became very concerned after peers made her aware of her asymmetric blink. Patient 3 was asymp tomatic and did not notice anything particular. Therapy and Outcome. Lagophthalmos resolved spontaneously within three months after surgery, first by improvement of voluntary eyelid closure and then of spontaneous blinking. Conclusions. Temporary lagophthalmos can occur as a complication of external dacryocystorhinostomy, most likely due to damage of the (onlyrecently 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 oculimuscle.
