External Dacryocystorhinostomy with & without Silicon Tube Intubation in Chronic Dacryocystitis with Nasolacrimal Duct Block

چکیده
The aim of the study was to compare the outcome of external DCR with and without stenting with silicon tube and analyse the results of silicon intubation whether it improves the overall success rate of DCR. Success rate for external DCR without STI was 80% in our study .Success rate for DCR with STI rose to 92%.Therefore DCR with STI is a highly successful procedure with a success rate of over 90%.Using the ST is a fairly simple procedure and takes just a few minutes to intubate the anastamosis.By using the ST the commonest cause of failure ie the closure of common canalicular opening is prevented thereby enhancing the success rate of DCR.External DCR still is a preferred modality of treating CDC as compared to Endoscopic DCR or Laser DCR, having a much better rate of success over these procedures.

متن کاملSilicone Intubation Indications in External Dacryocystorhinostomy
External dacryocystorhinostomy (DCR) is the gold standard surgical technique for the treatment of nasolacrimal duct obstruction (1). Since its introduction by Gibbs in 1967, intubation with silicone tubes has been widely used in lacrimal duct surgery (2). However, effect of silicone intubation on patency of lacrimal system during external DCR in cases of primary nasolacrimal duct obstruction (N...
