Experience with endoscopic dacryocystorhinostomy using four methods
2010
Objective: Evaluation of four methods of endoscopic dacryocystorhinostomy (EDCR) for treating chronic dacryocystitis.Study Design: Case series with chart review.Materials and Methods: A total of 1450 patients underwent EDCR for epiphora, chronic dacryocystitis, and blocked nasolacrimal ducts. Relief from epiphora, dacryocystitis, and patency of the fistula for all four techniques was compared. A total of 292 patients underwent incision and drainage, 343 patients had grommets inserted, 258 had silastic lacrimal stents inserted, and 557 had the medial wall of the lacrimal sac (LS) removed. Parameters of success were 1) resolution of epiphora, 2) no further attacks of dacryocystitis, and 3) patency of the new fistula.Results: Sixty-five percent failed the incision method, and 68 percent of the patients who underwent the grommet method failed. All 258 patients with lacrimal stents experienced success while the stent remained in situ. Ten patients required removal because the stents created corneal opacities. ...
