ePoster Number: 234
Purpose
Evaluation of the efficacy and surgical outcome of trans-canalicular DCR in comparison to open external dacryocystorhinostomy in management of patients with nasolacrimal duct obstruction.
Methods
The study was conducted on 100 patients with canalicular nasolacrimal duct obstruction who were allocated into five groups with different procedures; group A subjected to conventional open DCR, group B subjected to trans-canalicular with connection between sac and inferior meatus by both limbs of the silicon in nasolacrimal duct, group C subjected to trans-canalicular with one limb through the NLD and the other through the middle meatus, group D subjected to trans-canalicular with both limbs of silicon tube passing to the middle meatus and group E subjected to trans-canalicular with a catheter introduced between the sac and middle meatus through a skin incision with one or both limbs of silicon tube passing to the middle meatus.
Results
Time of surgery was statistically significant longer among cases of conventional open DCR compared with cases subjected to trans-canalicular DCR; 74.55±11.42a vs. 22.30±11.06b min. respectively. Our study revealed that Anatomical Success : (85.0%) for Group A: conventional open DCR , (90.0%),Group B: trans-canalicular with procedure l , (85.0 %) Group C: trans-canalicular with procedure ll), (85.0%) Group D: trans-canalicular with procedure lll , (80.0%) Group E: trans-canalicular with procedure Vl,
And Functional Success was (80.0%) for Group A: conventional open DCR , (85.0%),Group B: trans-canalicular with procedure l , (85.0 %) Group C: trans-canalicular with procedure ll), (85.0%) Group D: trans-canalicular with procedure lll , (80.0%) Group E: trans-canalicular with procedure Vl . Cases in group C who were subjected to trans-canalicular dacryocystorhinostomy with connection between sac and inferior meatus by one limb through the NLD and the other through the middle meatus were statistically significant more satisfied than other groups after 1 week and one month from the operation. Intraoperative bleeding was statistically significant higher among cases
of conventional open DCR compared with cases in other groups subjected to transcanalicular dacryocystorhinostomy; 110.90±20.54 vs. 43.50±10.14 ml.
Conclusion
: Transcanalicular dacryocystorhinostomy allows surgeons to perform a minimally invasive and safe procedure and offers similar accuracy in objective and subjective outcomes assessment compared with external dacryocystorhinostomy.
