RESUMEN
<p><b>OBJECTIVE</b>To explore the clinical effect of using dorsal two wing-shaped flap to reconstruct finger web for treatment of congenital syndactyly.</p><p><b>METHODS</b>This technique has been used in 19 children with congenital syndactyly. At the dorsum, a flap with V-shaped tip and two wing-shaped pedicle were designed and was just sewed up with an anchor-shaped incision at the palm. The web was primarily reconstructed without skin graft at base of fingers. Distal end of fingers were separated by using serrated flap and were closed after removal of fatty tissue. At some cases with tight skin connection. The defect area at lateral and distal end of fingers was closed by small pieces of skin graft.</p><p><b>RESULTS</b>All the webs were reconstructed primarily without skin graft at the base of fingers. 7 cases with tight skin connection had small pieces of skin graft at lateral and distal end of fingers. Primary healing was achieved in all cases. After 1 to 6 months of follow-up, both the appearance and function were satisfactory without conspicuous scar. The reconstructed finger webs were in normal depth and width.</p><p><b>CONCLUSIONS</b>Primary web space can be achieved by dorsal two wing-shaped flap without skin graft at base of fingers. It is one of the best choices for treatment of congenital syndactyly.</p>
