Abstract:
This report assessed clinical conditions leading to recurrent dacryocystitis and success rates of its treatment by endonasal endoscopic dacryocystorhinostomy. Forty-eight patients with recurrent dacryocystitis underwent endonasal endoscopic surgery and were followed up for at least 6 months. High bone windows, small bone window openings, small lacrimal sac stomas, scar tissues, and organic diseases of the nasal cavity led to fistula closure. Out of 48 patients, 45 (93.8%) patients were cured by endonasal endoscopic surgery. Endonasal endoscopic dacryocystorhinostomy is beneficial for recurrent dacryocystitis.
