Early Endonasal Dacryocystorhinostomy for Acute Dacryocystitis: A Systematic Review and Meta-Analysis.

Objective: The aim of this meta-analysis is to compare the outcomes of early endonasal dacryocystorhinostomy (DCR) with delayed DCR in the treatment of acute dacryocystitis (AD).

Methods: A comprehensive electronic search of PubMed, Embase, Web of Science, and the Cochrane Library databases was conducted up to November 11, 2023. Data synthesis was performed using Review Manager 5.4, and forest plots were generated for each outcome measure. Potential publication bias was assessed using funnel plots and Egger's test.

Results: Six studies involving 288 patients were included in the meta-analysis. Overall, the success rate of early endonasal DCR was comparable to that in the delayed DCR group (odds ratio [OR] = 1.52, 95% confidence interval [CI]: 0.81-2.85, P = .19). Furthermore, in comparison with the delayed DCR group, early endonasal DCR significantly reduced the time for medial canthus swelling resolution (mean differences [MD] = -4.92, 95% CI: -5.46 to 4-.37, P < .00001) and complete resolution of symptoms (MD = -17.70, 95% CI: -23.88 to -11.52, P < .00001).

Conclusion: Primary early endonasal DCR seems to be a promising and favorable approach for managing AD with comparable efficacy and faster relief of symptoms compared to conventional delayed DCR.
