New Simple Technique for Syndactyly Release.

Can good functional and cosmetic result be achieved in syndactyly separation using a straight midline incision with a hexagonal dorsal skin flap?

methodsWe performed 39 web reconstructions at a median of 20 months of age (11-43 months) to 26 consecutive children (21 male) with 30 simple, 4 complex, and 5 complicated syndactylies. Eighteen of the simple syndactylies were incomplete, ending at the proximal interphalangeal joint in 15 and at the distal interphalangeal joint in 3. Inguinal skin grafts were used in 2 children with either complex or complicated syndactyly. Operation time was recorded. Complications were registered. Height of the new web spaces was calculated. Parents' satisfaction on both functional and cosmetic outcome was assessed using a Visual Analog Scale from 0 to 100.

resultsDuration of one web reconstruction ranged from 50 to 95 minutes in simple incomplete, 56 to 135 in simple complete, 116 to 151 in complex, and 72 to 123 in complicated syndactylies. One child had a self-induced bilateral postoperative infection that lead to web creep. Two patients developed hypertrophic scars, which responded well to silicone treatment. Mean cosmetic and functional Visual Analog Scale scores were 87 (45-100) and 92 (63-100), respectively, at a mean follow-up of 1.3 years (range, 0.5-3.7).

conclusionWeb reconstruction using a hexagonal dorsal skin flap and straight midline incisions with closure at mid-lateral lines is safe, with good cosmetic and functional outcome in our short-term follow-up.
