title: Powered endoscopic dacryocystorhinostomy with mucosal flaps without stenting.
abstract: Dacrycystorhinostomy (DCR) is a procedure performed to drain the lacrimal sac in cases of nasolacrimal duct obstruction or in chronic dacryocystitis. It can be performed externally or endoscopically. This is a prospective, nonrandomized study involving twenty-two consecutive patients (16 Females and 6 Males; mean age 45.54 y; range 18-74 y) who presented to the DCR clinic with epiphora secondary to nasolacrimal duct obstruction and recurrent infection. All patients underwent primary powered endoscopic DCR. A total of 24 procedures were performed using a standardized surgical technique. Post-operatively, symptom evaluation and endoscopic assessment of the newly created lacrimal ostium were done. Twenty-two of the 24 DCR's were patent after a mean follow-up of 21.5 months, yielding a success rate of 91.66%. Patency was assessed by symptomatic evaluation and endoscopic visualization at each post-operative visit. Two patients had complications, one orbital fat exposure and the other secondary haemmorhage. The two failures were due to synechiae formation. Therefore, powered endoscopic DCR with mucosal flaps without stenting has a success rate comparable to that achieved with stents and external DCR.
