Epiphora, or abnormal tearing, occurs because of the blockage in the lacrimal drainage system, which impairs normal tearing channeling into the nose. It is essential that with proper history and examination including syringing and probing, a correct diagnosis is made. Syringing and probing are performed only in congenital and acquired nasolacrimal duct obstruction (NLDO).
Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal drainage system. Endoscopic dacryocystorhinostomy (E-DCR) using telescopes has gained a lot of momentum among otolaryngologists, since the outcomes are comparable to the external approach. Advances in surgical technique and a better understanding of the anatomy have resulted in improvements in outcomes. The anatomy of the lacrimal system will be discussed in detail including the surgical indications and techniques of DCR. The advantages, results, and complications of surgery will be highlighted.
