title: [Traumatic Lacrimal Duct Stenosis: Demographics and Success Rate of Surgical Procedures for Secondary Treatment].
abstract: BACKGROUND
  Traumatic lacrimal duct stenosis can be the result of sharp trauma of the eyelid, indirect trauma or surgery in the nasoorbital region, as well as burns, chemotherapy and radiation of the facial region. The aim of the study is to present the demographics, patient satisfaction, and course of different surgical procedures for secondary treatment of traumatic lacrimal duct stenosis.
  
  
  METHODS
  We retrospectively reviewed the medical records of 50 patients who required surgery for traumatic lacrimal duct stenosis from 2009 to 2011 at the University Eye Hospital in Muenster. The evaluation included the following criteria: age, sex, duration of symptoms, complication rate and the rate of recurrence. We systematically evaluated the medical data and asked the patients about the recent symptoms via telephone questionnaire.
  
  
  RESULTS
  60 eyes of 50 patients were included (18 women; 32 men; age: 51.8 ± 17.1 years); 34 eyes (56.7 %) had already had operations of the lacrimal system. The success rate was 58.1 %. The mean postoperative follow-up was 52.3 ± 10.7 months. In 11 cases (18.3 %), a dakryocystorhinostomy (DCR) was necessary.
  
  
  CONCLUSIONS
  Traumatic lacrimal stenosis is more common in men, and has a poorer prognosis than lacrimal duct stenosis from other causes.
