Background: The aim of our study is to highlight the factors causing failure in endoscopic dacryocystorhinostomy (DCR) surgery. Understanding these factors will result in an enhancement in the success rate of endoscopic DCR.
Materials and methods: A total of 162 patients who underwent endoscopic DCR surgery between January 2013 and December 2016 were evaluated retrospectively. Thirty-eight failed endoscopic DCR cases of our hospital and those referred from elsewhere were included in our study. All the cases were reviewed and the likely causes leading to failure of the first surgery were analyzed.
Results: The most common cause of endoscopic revision surgery in our study was inadequate sac opening and the next was inadequate osteotomy of the frontal process of the maxilla. Endoscopic revision surgery was performed in 34 patients, while silicone tube intubation under endoscopy was performed in 13 patients. The overall success rate of the revision surgery was 94%.
Conclusion: Most of the factors leading to failure of surgery are avoidable and can be prevented by careful selection of patients and by the use of meticulous surgical techniques.
