Abstract
Dacryocystorhinostomy is a common surgery and aims at creating a new ostium that bypasses the obstructed nasolacrimal duct. It is amply evident that many finer physical and functional details of the ostium need to be evaluated postoperatively in an orderly manner to appreciate pathological behaviors early on and institute corrective measures toward prevention or treatment. This chapter presents a DCR ostium protocol for a detailed evaluation and also the DCR ostium or the DOS scoring to standardize the evaluation.
