The use of a dorsal double-wing flap without skin grafts for congenital syndactyly treatment: A STROBE compliant study.

Numerous techniques have been developed that use various flaps to treat syndactyly. Skin grafts have often been used to cover remaining surgical defects. The long-term aim of surgery is to find new methods of separating the digits without using skin grafts. This paper describes a new surgical technique for the correction of simple, incomplete, and complete syndactyly. The technique consists of a dorsal double-wing flap to cover the newly created web space and zigzag incisions in the fingers, thus avoiding the use of skin grafts in this space. Overall, 35 web spaces in 24 patients were treated using this technique. Patient follow-up ranged from 6 months to nearly 5 years. There were no complications such as hematoma, infection or flap necrosis, and no fingers needed skin grafts after separation. The average operative time for each web space was approximately 45 minutes. Ninety-seven percent of patients treated with the dorsal double-wing flap procedure achieved good function, and superior cosmetic results following a single surgery. The technique is simple, rapid, safe, and easily performed and does not require the use of skin grafts.
