ABSTRACT

Despite the success of dacryocystorhinostomy (DCR) in the treatment of lacrimal drainage system (LDS) obliteration and the use of medical and surgical methods to prevent its recurrence, the number of relapses reaches 37%. The main etiological factor leading to this pathology is partial (stenosis) or complete obstruction of the ostium. PURPOSE: To study the effectiveness of endonasal balloon dacryoplasty in partial or complete obstruction of dacryocystorhinostomy ostium. MATERIAL AND METHODS: The study involved 122 patients (127 cases) with relapse after endonasal endoscopic dacryocystorhinostomy performed 6 months to 3 years ago to treat partial or complete obstruction of lacrimal sac neck. Patients of the 1st group (41 cases) underwent endonasal balloon dacryoplasty, patients of the 2nd group (42 cases) underwent endonasal balloon dacryoplasty with bicanalicular silicone stenting, patients of the 3rd group (44 cases) underwent revision endonasal endoscopic dacryocystorhinostomy with bicanalicular silicone stenting. RESULTS: After 12 months follow-up, positive results were observed in 85.7% of cases with ostium stenosis and 80.0% of cases with complete obstruction of the ostium among group 1 patients; in 86.4% of cases with ostium stenosis and 85.0% of cases with complete obstruction of the ostium among group 2 patients; and in 81.0% of cases with ostium stenosis and 82.6% of cases with complete obstruction of the ostium among group 3 patients. CONCLUSION: The obtained results give grounds to recommend inclusion of endonasal balloon dacryoplasty in the standards of treatment for patients with partial (stenosis) and complete obliteration of dacryocystorhinostomy ostium.
