Abstract :

Introduction: Epiphora is an annoying symptom, embarrassing the patient both socially and functionally, two widely acceptable treatment modalities of epiphora due to nasolacrimal duct obstruction (NLDO) are external and endoscopic dacryocyctorhinostomy (DCR). Purpose of this study is comparison of complications and success rate of these two methods in patients with NLDO. Material and methods: Retrospective study of patients who underwent surgical endoscopic and external DCR and comparison of their success rate and postoperative complications from 2012–2013 with 6 months follow up in otolaryngology department of shahid sadughi hospital in yazd. Results: A total of 105 patients underwent surgeries for NLDO (52 patients in endoscopic and 53 patients in external group). Min age was 49 years and 62.4% of subjects were female. There was not any significant difference in success rate between two groups (endoscopic 92.3% versus external 86.7%, P value=0.35). Epistaxis and nasal discharge occured just in endoscopic DCR [ epistaxis 7(13.5%) and nasal discharge 8 (15.3%)]. Some complications occured exclusively in external DCR group such as: Unacceptable scar 15 (28.4%), wound dehiscence 5(9.4%), transient lagophtalmus 2(3.7%), transient orbicularis hypototony 1(1.8%). Failure rate in functional subgroup was higher. In endoscopic DCR group in anatomic obstruction special complications (epistaxis and nasal discharge) were higher than functional subgroup (P
