Clinical Trial: External Versus Powered Endoscopic Dacryocystorhinostomy With Mitomycin C for Primary Acquired Nasolacrimal Duct Obstruction

U.S., Aug. 11 -- ClinicalTrials.gov registry received information related to the study (NCT07754058) titled 'External Versus Powered Endoscopic Dacryocystorhinostomy With Mitomycin C for Primary Acquired Nasolacrimal Duct Obstruction' on July 21.

Brief Summary: Primary acquired nasolacrimal duct obstruction causes persistent tearing because tears cannot drain normally from the eye into the nose. The purpose of this randomized study was to compare two operations used to restore tear drainage: external dacryocystorhinostomy, performed through a small skin incision near the inner corner of the eye, and powered endoscopic dacryocystorhinostomy, performed through the nose using an endoscope and powered instruments, with mitomycin C applied duri...
