| Abstract: | SummaryWith the introduction of endoscopes for endonasal surgery, there have been an increasing number of endonasal dacryocystorhinostomies (DCR) performed. The advantages of the endonasal approach include the avoidance of an external facial scar and reduced risk of damage to the medial canthal ligament. We described our experience with the use of the Hall Osteon drill for endoscopic DCR. This procedure has been found to be technically reliable giving satisfactory post-operative results in 16 patients suffering from nasol-acrimal duct obstruction. The follow up was up to 12 months with a mean of 5 months. Three patients who had residual post-operative epiphora were considered as failures. There were no major complications and minor complications included one case of periorbital ecchymosis, one unretrieved silicone tube and a minor vestibule abrasion. The preliminary results suggest that the endoscopic drill-assisted DCR could offer a reliable treatment in patients with epiphora due to nasolacrimal duct obstruction. |
