Randomized Trial on Silicone Intubation in Endoscopic Mechanical Dacryocystorhinostomy (SEND) for Primary Nasolacrimal Duct Obstruction – Corrected Proof

Purpose: To study the effect of bicanalicular silicone intubation on endonasal endoscopic mechanical dacryocystorhinostomy (EEM-DCR) for primary acquired nasolacrimal duct obstruction (PANDO).Design: Randomized clinical trial.Participants: A total of 120 consecutive adults (103 females) with a presenting age of 64±13.7 years (range, 39–92 years) underwent EEM-DCR for PANDO from November 2005 to May 2009 in a lacrimal referral center.Methods: The EEM-DCR was performed by 2 lacrimal surgeons using standard techniques. Patients were randomly assigned to receive or not receive bicanalicular silicone intubation for 8 weeks. No antimetabolite was used. All patients received a course of oral antibiotics during nonabsorbable nasal packing (Read more...)
