Abstract & Overview
Introduction: Recurrent chronic dacryocystitis represents a complex inflammatory condition frequently associated with failure of previous surgical interventions and persistent mechanical obstruction of the lacrimal drainage system. Objective: To present a case of recurrent chronic dacryocystitis after multiple unsuccessful surgical procedures and to highlight the role of laser‑assisted endoscopic dacryocystorhinostomy as a revision technique. Materials and Methods: We report the case of a patient with recurrent symptoms following two previous endoscopic dacryocystorhinostomies with nasolacrimal stent placement. Clinical examination, computed tomography of the paranasal sinuses, endoscopic findings, surgical management, and postoperative course were analyzed. Results: Imaging revealed rhinostomy stenosis associated with lacrimal sac lithiasis, representing a persistent mechanical cause of obstruction. Laser‑assisted endoscopic dacryocystorhinostomy using a diode laser was performed without stent placement, allowing precise removal of fibrotic tissue and obstructive material. The postoperative course was favorable, with complete resolution of epiphora, absence of purulent discharge, and maintained rhinostomy patency at 3‑month follow‑up. Conclusions: Laser‑assisted endoscopic dacryocystorhinostomy may represent an effective revision strategy in recurrent chronic dacryocystitis caused by persistent mechanical obstruction. Accurate identification of the underlying mechanism of surgical failure is essential for achieving durable functional outcomes.
