Abstract

Introduction-Prospective study to assess the success of repeat DCR surgery without flap anastomosis. Material and Methods- Included 134 Pts from March 2011-Dec20.Incision through the original scar. Roughly 1/4th lacrimal sac mucosa around comman canaliculi opening in sac is saved so that the sac remains as a disc with punctum in its middle. Osteum in the nasal bone and nasal mucosa was made using Arruga’s bone trephine. Upper part of the remaining lacrimal sac was sutured with subcutaneous tissue / periosteum of medial side. Sac syringing with 1 ml of 0.4mg/ml Mitomycin c (MMC) was done. Results: 132 pts(98.5%) out of 134 patients were symptom free/patent nasolacrimal duct on syringing during follow up. Results were strongly significant (p<.001).Discussion-Because the most common cause of DCR failure is fibrosis at osteotomy site, MMC was used . Conclusion: Result suggests that our technique had high success rate with ease and reliability in repeat surgery of failed DCR
