Patients were retrospectively categorized according to the surgical procedure received: the research group underwent endoscopic endonasal DCR, whereas the control group underwent traditional external DCR.

No statistically significant between-group differences were detected in short-term anatomical or functional success. Larger prospective studies with adjustment for potential confounders and longer follow-up are required to confirm these findings.<\/jats:p>\n
