Limited endoscopic high septoplasty prior to endonasal dacryocystorhinostomy: our experience of nine cases

Abstract

Primary acquired nasolacrimal duct obstruction is a clinical syndrome of unknown cause, manifested by epiphora, infection, blurred vision, and ocular and facial pain. Conservative care is usually ineffective in patients with chronic conditions; thus, dacryocystorhinostomy (DCR) has become the gold standard of treatment for such patients. Since the advent of endoscopic technologies, most patients have undergone endonasal (EN-)DCR; the success rate is comparable to that of external (EX-)DCR.
