Endoscopic lacrimal surgery

There are many causes that cause dacryocystitis. Most of them corresponds to the nasolacrimal duct obstruction, causing stasis predisposes to infection by bacterial overgrowth. Chronic dacryocystitis is a slight inflammation of the lacrimal sac may be the only symptom. By pressing the sac, pus could regurgitates through the punctum. The sac can end distended due to the accumulation of secretions and cause a large mucocele.

Dacryocystorhinostomy (DCR) Endoscopic can restore communication between the lacrimal sac and the nasal cavity via endonasal without making external incisions in the skin of the face. In many cases, it left in place a probe into the lacrimal duct to try to ensure patency of the new hole. The probe is maintained for a variable time, and retire depending on the surgeon and the evolution of the healing process. The intervention can be performed under general or local anesthesia and a small nasal packing is placed over a variable period of time (Figure 1) (Figure 2) (Figure 3).
