Mucoid reflux from lacrimal sac

Additional Notes: Length 00:59
This is Richard Allen at the University of Iowa. This video demonstrates an external dacryocystorhinostomy in which manipulation of the lacrimal sac results in mucoid reflux. The Freer periosteal elevator is used to elevate the periosteum from the underlying bone. The lacrimal sac is then elevated from the lacrimal sac fossa. During this maneuver, mucoid material is noted to come from the upper and lower puncta. This represents a dilated lacrimal sac full of mucoid material. To me, this is a positive sign during surgery. It tells me that this surgery will likely result in resolution of the patient's symptoms and be successful. Due to the amount of mucoid reflux, I will place this patient on systemic antibiotics post-operatively, usually cephalexin for 7 days.
