Comparison of Modifications in Flap Anastomosis Patterns and Skin Incision Types for External Dacryocystorhinostomy: Anterior-Only Flap Anastomosis with W Skin Incision versus Anterior and Posterior Flap Anastomosis with Linear Skin Incision

摘要: 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 44 (group A) suturing anterior posterior flaps (H-flap) sac curvilinear whereas in 38 35 B) DCR was performed only (U-flap) W incision. Results. The success rate evaluated according to patency scar assessment scores. Patency achieved 78 (88.6%). In terms groups, (88.0%) group A 34 (89.5%) B. There no statistically significant difference rates between groups. Further, there concerning cutaneous Conclusion. Our suggests that anastomoses or both have similar rates; is easier perform shortens operative time. addition, a reasonable alternative for reducing formation.
