Comparison of Monocanalicular and Bicanalicular Intubation in Canalicular Laceration Reconstruction

Background and Objectives: Traditionally canalicular lacerations were repaired by bicanalicular Crawford intubations and anastomosis of two cut ends. Recently monocanalicular silicon stent was used for canalicular laceration repairing. In this study we compared the success and complations rate of canalicular laceration repairing with monocanalicular (Mini-Monoka) and bicanalicular (Crawford) intubation. Materials and Methods: In group one, 20 canaliculi repaired with Mini- Monoka intabution and in group two, 50 canaliculi repaired with Crawford intubation. The stent left in place for 3 months. Anatomical patency was ensured by probing and irrigation at the time of stent removal and 3 months later. Subjective epiphora evaluated by grading to success, fair and poor. Data were analyzed by EP (version 6) software and chi Square. Statistically significant value was defined as P<0.05. Results: At final follow up anatomical patency was confirmed in 19 and 49 canaliculi in group I and 2, respectively (P=0.49). Subjective improvement was observed in 80% and 64% in group I and 2, respectively (P=0.31). Complications were granulation tissue (group 1=2 group 2=1), premature stent dislocation (group 1=3 group 2=3), canalicular stricture (group 1=3 group 2=9) and slit punctum(group 1=0 group 2= 16 ). No corneal complication was observed in both groups. Conclusion: The success rate of both methods of intubation was comparable. Slit punctum was seen only in bicanalicular intubation so Mini - Monoka monocanalicular intubation may be a suitable substitute for Crawford silicone tube
