Abstract
Introduction: Dacryocystorhinostomy (DCR) is a surgical technique used to establish communication between the lacrimal duct and the nasal cavity. Traditionally, this procedure has been performed externally, but recent advances in endoscopic
surgery have increased its use. As lacrimal duct disorders are common in otorhinolaryngology
surgical practice, it is important to characterize this population and identify post-surgical results. Objectives: The objective of this study was to describe the surgical technique and outcomes of adult patients undergoing endoscopic transnasal dacryocystorhinostomy (DCR) at Hospital Universitario San Ignacio between 2017 and 2020. Materials and Methods: A retrospective descriptive study was conducted on adult patients who underwent endoscopic transnasal DCR between
2017 and 2020. Results: Ninety-three adult patients were analyzed, with a mean age of 61 years at the time of the procedure. Obstruction of the lacrimal duct was the main etiology identified in 70.6% (74 patients). Improvement in epiphora was found
in 82% (77 patients) with a range of 60% to 100%. During endoscopic follow-up, lacrimal sac patency was identified in 94.6% of cases (88 patients). On average, removal of the Crawford set was performed at 10.8 months. Discussion: Lacrimal duct obstruction manifests with epiphora, recurrent infectious processes, or visual changes. It has been shown that DCR effectiveness rates are comparable to those
obtained in external approaches, with the advantage of a lower risk of complications and absence of external scars.
