Purpose. To compare the outcomes of external dacryocystorhinostomy (E-DCR) by using two different flap anastomosis patterns and skin incision types. Methods. This study included 79 patients (88 eyes) with lacrimal drainage system disorders who underwent E-DCR surgery. Fifty eyes of 44 patients (group A) underwent E-DCR by suturing anterior and posterior flaps (H-flap) of the lacrimal sac with curvilinear skin incision whereas in 38 eyes of 35 patients (group B) DCR was performed by suturing only anterior flaps (U-flap) with W skin incision. Results. The success rate was evaluated according to lacrimal patency and scar assessment scores. Patency was achieved in 78 patients (88.6%). In terms of groups, patency was 44 eyes (88.0%) in group A and 34 eyes (89.5%) in group B. There was no statistically significant difference in the success rates of lacrimal patency between the two groups. Further, there was no statistically significant difference concerning cutaneous scar scores. Conclusion. Our study suggests that anastomoses of only anterior flaps or both anterior and posterior flaps have similar success rates; suturing only anterior flaps is easier to perform and shortens the operative time. In addition, W skin incision is a reasonable alternative to curvilinear incision for reducing scar formation.
