Endoscopic Dacryocystorhinostomy

AbstractPurpose of the ReviewEndoscopic dacryocystorhinostomy (DCR) is a recognized procedure performed to treat epiphora caused by anatomical or functional obstruction of the nasolacrimal apparatus. The purpose of this review is to discuss our experience with the endoscopic approach to DCR.Recent FindingsNasolacrimal duct dysfunction has many different etiologies. The diagnosis is clinical, so a thorough clinical history and physical exam are required to confirm the diagnosis of epiphora. The etiology is confirmed with further exams including the dye disappearance test, Jones tests, endoscopic evaluation, and imaging when required. Endoscopic DCR provides a better visualization of the surgical field than the previously described external approach.SummaryAn understanding of the endonasal and lacrimal apparatus anatomy, the importance of wide marsupialization of the lacrimal sac, and meticulous care with the mucosa are crucial for the success of the procedure.
