Description
Background: Lacrimal bypass surgery is a crucial intervention for patients with obstructed lacrimal pathways, particularly when traditional dacryocystorhinostomy (DCR) is not feasible. Autogenous tissue grafting has emerged as a promising alternative, offering better integration and reduced risk of rejection. However, comprehensive anatomical and clinical studies on its effectiveness are limited. Aim: To evaluate the anatomical feasibility and clinical effectiveness of lacrimal bypass surgery using autogenous tissue grafting. Methods: This descriptive study included 200 participants, comprising 100 cadaveric specimens and 100 patients who underwent lacrimal bypass surgery. Anatomical measurements of the lacrimal fossa and pathway were taken from cadaveric specimens. Clinical data were collected from patient medical records, including preoperative and postoperative symptom scores, surgical outcomes, and complications. Statistical analysis was performed using SPSS version 22.0. Results: Anatomical measurements revealed an average nasolacrimal duct length of 15.3 mm and diameter of 3.2 mm. The surgery had an 88% success rate, with significant improvements in symptom severity, pain, and frequency (p < 0.001). Complications were minimal, with postoperative infections in 3% of cases and graft displacement in 2%. Anatomical variations were observed in 19% of cadaveric specimens. Conclusion: Lacrimal bypass surgery using autogenous tissue grafting is effective, with high success rates and significant symptom improvement. The low complication rate underscores its safety, although anatomical variations necessitate tailored surgical approaches. Recommendations: Further research with larger cohorts and extended follow-up periods is recommended to validate these findings and refine surgical techniques. Personalized surgical planning based on detailed anatomical assessments can optimize outcomes.
