What this trial studies

This study aims to evaluate the effectiveness of two different surgical techniques during external dacryocystorhinostomy (DCR) for patients with acquired nasolacrimal duct obstruction. It will involve a prospective interventional comparative design, where 60 eyes will be treated either with anastomosis of posterior mucosal flaps or with amputation of these flaps. The study will assess intraoperative details and postoperative findings to determine which method yields a higher success rate. Participants will be informed about the study and will provide written consent before undergoing the procedure.

Who should consider this trial

Good fit: Ideal candidates include patients with chronic dacryocystitis, primary nasolacrimal duct obstruction, lacrimal mucoceles, or lacrimal fistulas.

Not a fit: Patients with recurrent cases, those under 5 years of age, or individuals with associated nasal pathology may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes for patients suffering from tear duct obstructions.

How similar studies have performed: While there have been various modifications to DCR procedures, this specific comparison of flap management techniques is relatively novel.
