Endoscopic dacryocystorhinostomy

Mymensingh Med J. 2011 Jan;20(1):28-32.


Dacryocystorhinostomy (DCR) is the treatment of distal nasolacrimal duct blockage. It has got many advantages of over external DCR with higher patient's acceptance. Twenty one consecutive cases of endoscopic DCR were studied during the period of two and a half years with a mean follow up period of 13.12 months (SD=7.05). The mean age of cases was 42.95 years (SD=14.49). In most of the cases the cause was either idiopathic (71.43%) or inflammatory (23.81%). The techniques used for making bony window were chisel-hammer (19.50%), powered drill (23.81%), Kerrison punch forceps (14.29%) or combination of powered drill and Kerrison punch forceps (42.86%). Silicon stent was used in 71.43% cases. There was no significant peroperative complication; premature extrusion of stent (4.76%), synaechia (9.52%), excessive granulation tissue formation (9.52%) and stomal stenosis with recurrence of symptoms (9.52%) were the complications noticed here. Anatomical success with patent stoma was observed in 90.48% cases but symptomatic improvement with dry comfortable eyes were seen in 86% cases. There was no statistically significant difference of outcome between this study and that of recently published studies (p>0.05). Some comparative studies showed both higher and lower success rates of endoscopic DCR than external procedure but there was no significant difference (p>0.05).
