title: Endoscopic conjunctivodacryocystorhinostomy with Jones tube placement.
abstract: OBJECTIVE
  Conjunctivodacryocystorhinostomy (CDCR) with Jones tube placement as described by Jones has traditionally been performed as an "open" or external procedure by means of medial canthal incision. Application of endoscopic technique for CDCR with Jones tube placement has not been well described in the peer-reviewed literature.
  
  
  METHODS
  Retrospective nonrandomized comparative trial.
  
  
  METHODS
  Ten patients with epiphora secondary to canalicular stenosis.
  
  
  METHODS
  A total of 13 consecutive CDCR with Jones tube procedures were reviewed. Five procedures (performed predominantly in the early study period) were done by means of a traditional external approach with a medial canthal incision. Eight procedures were performed with an intranasal endoscopic approach and instrumentation with Jones tube placement under direct endoscopic visualization.
  
  
  METHODS
  Total operative time, estimated blood lost, intraoperative, and postoperative complications and need for secondary surgery were evaluated.
  
  
  RESULTS
  All procedures were successfully completed with no intraoperative complications. Average operative time was 59 minutes in the endoscopic group and 74 minutes in the external group. Average blood loss was 3.5 ml and 4.4 ml in the endoscopic and external groups, respectively. Postoperative adjustment of tube size or position (performed as an office procedure with topical/local anesthesia) was common: five of eight endoscopic and three of five external approach. Two patients in the endoscopic group required secondary surgery for anatomic reasons. Ultimately, all cases in both groups demonstrated patent, retained Jones tubes and relief of epiphora.
  
  
  CONCLUSIONS
  Endoscopic technique appears to be a reasonable approach for CDCR with Jones tube placement. Operative time and blood loss were comparable in the two groups, with the endoscopic group being slightly lower for each variable. Endoscopic Jones tube placement can be accomplished with readily available instrumentation. In this series, we did not find it necessary to use laser, radiofrequency, or monopolar devices for intranasal hemostasis.
