Background and Objectives : The conjunctivodacryocystorhinostomy (CDCR) is rarelyperformed in epiphora, which is caused by complete proximal bicanalicular obstruction. Thepurpose of this study is to analyze the characteristics, clinical results and complications of patientswho underwent CDCR.
Subjects and Method : We enrolled 12 patients who underwent CDCR due to proximal canalicularobstruction from 2006 to 2019. We retrospectively analyzed the causes of epiphora,trauma history, the cause of revision operation and the clinical outcome.
Results : A total of 12 patients (7 males and 5 females) underwent CDCR (mean age 46 years).
The causes of trauma were such as laceration (n=7, 58%) and iatrogenic (n=1, 8%), idiopathicobstruction (n=4, 33%). After the initial surgery, 5 patients (41%) were categorized in good outcomeand the Jones tube was located well in 6 (50%) patients. Revision surgery was performedin 6 (50%) cases, with 4 cases having good outcome. The success rate of CDCR, including revisionsurgery, was increased to 83%. Most common cause of revision surgery was tube migration.
In addition, the subjective outcome in patients with traumatic causes were worse butit had no statistical significance compared to that of patients with idiopathic and iatrogeniccauses (p=0.07).
Conclusion : About a half of the patients had good recovery rate after the initial operation.
The outcome increased to 83% after revision operation. The success rate of CDCR for traumaticpatients was worse than for those with idiopathic and iatrogenic causes. It seems that accompaniedeyelid damage in traumatic patients may have affected the result of success rate.
