Endoscopic dacryocystorhinostomy (OCR)

Abstract

Congenital nasolacrimal duct obstruction (NLDO) usually resolves spontaneously during the first year of life. Persistent cases often requires probing, intubation, or balloon dacryocystoplasty. Refractory cases have been successfully managed by endoscopic dacryocystorhinostomy (DCR) in adults and children. Some children have a bony obstruction that must be opened with DCR, or some patients have acquired NLDO that requires DCR. The endoscopic technique is a safe and quick alternative to external DCR, which is considered the gold standard, but avoiding an external scar is preferable for many patients. We aim to explain the essential steps of endoscopic DCR, the potential risks, and an example of the dictated procedure note.
