A new concept of webspace reconstruction in syndactyly - An easily reproducible cross-shaped advancement flap

Abstract

Background and objectiveThe use of sizable dorsal flaps for webspace reconstruction without skin grafting can minimize complications in syndactyly correction. We report the technique and results of a cross-shaped advancement flap for reconstruction of the webspace and coverage of the lateral sides of the bases of the separated fingers in congenital syndactyly. MethodsFrom June 2018 to July 2020, 15 patients with simple or complex syndactyly for webspace reconstruction with a dorsal cross-shaped advancement flap were retrospectively studied. The patients' ages ranged from 5 to 144 months, with a median age of 12 months. Out of these 15 patients, six patients were suffering from bilateral involvement. Withey grading of web creep was used for postoperative evaluation. Scar hyperplasia was assessed using the Vancouver Scar Scale, and Visual Analogue Scale was applied to evaluate the subjective satisfaction of the children's families with the reconstructed finger appearance, pain and function. ResultsThere was no perioperative complication in the group. During an 8–17 months follow-up period, no secondary correction was needed in this group. The average score of Withey scale was 0.1, and Vancouver Scar Scale was 1.5. The Visual Analogue Scale score of appearance, pain and function was 1.8, 0.2 and 1.1, respectively. ConclusionThis technique can reconstruct the webspace and cover the lateral wall of the fingers for syndactyly correction without the risk for web creep or hypertrophic scar.
