Abstract
PURPOSE To determine the effectiveness of balloon dacryoplasty in the treatment of internal ostium stenosis after endoscopic dacryocystorhinostomy (EnDCR). METHODS A retrospective, noncomparative interventional case series of patients who underwent balloon dacryoplasty for post-EnDCR internal ostium stenosis were included. A balloon catheter was used in all procedures, with bicanalicular silicone intubation. Patient records were reviewed and data analyzed. Anatomical success was defined by functional endoscopic dye test, and functional success was defined as a subjective improvement in symptoms at last follow up. RESULTS Nineteen lacrimal systems of 18 consecutive patients were studied between July 2007 and September 2012. At a mean follow up of 20 months (range, 3-53 months), anatomical success rate was 84% (16/19 systems), whereas functional success was 74% (14/19 systems). No major complication was observed. CONCLUSIONS Balloon dacryoplasty is a minimally invasive procedure in the treatment of post-EnDCR internal ostium stenosis. It is a simple, safe procedure and can provide symptomatic relief to some of these patients. It can be considered as a treatment option for patients demonstrated with internal ostium stenosis after EnDCR.
