Ostium Shrinkage after Endoscopic Dacryocystorhinostomy – Corrected Proof

Objective: Ostium closure after endoscopic dacryocystorhinostomy (DCR) is the commonest cause for anatomic failure. We aimed to determine the changes in size of the DCR ostium over time and investigate the correlation of ostium size and surgical outcomes.Design: A single surgeon, prospective, nonrandomized, noncomparative, interventional case series.Participants: We included a consecutive series of patients who underwent powered endonasal DCR. All patients had radiologically confirmed nasolacrimal duct or canalicular obstruction.Methods: Patients were operated on by 1 surgeon (D.S.) and follow-up was at 4 weeks and 12 months. Ostium sizes were measured at the end of surgery and at 4 weeks and (Read more...)
