[The free serratus carpaccio flap: indications and technique]. / Die freie Serratus-Carpaccio-Lappenplastik: Indikationen und Technik.

PURPOSE: Soft tissue reconstructions of the hand require a thin and resistant flap palmarly as well as sliding abilities between the extensor tendons and the flap on the dorsum of the hand. Elasticity is required to maintain the normal wrist range of motion. One option in these cases is the free serratus fascia flap that sometimes shows limitations regarding resistance as well as reliability. Here, we describe an easy modification including a thin muscle cuff in the serratus fascia flap - the serratus carpaccio flap - that improves the ease of flap harvest and morbidity rates. METHODS: The indications for the serratus carpaccio flap, the technique of flap harvest and contouring as well as flap inset are described in detail. Clinical examples are given. RESULTS: The main advantage of the serratus carpaccio flap is the ability of the surgeon to adapt the flap thickness to the recipient site requirements. This allows excellent results regarding contour and function. Split thickness skin grafting fromthe instep region of the foot additionally allows optimal results for palmar as well as plantar defect reconstruction. Eighteen flaps for soft tissue defects of the hand (n = 5), foot (n = 10), and lower leg (n = 3) were performed. Complications included one flap loss, one venous re-anastomosis, two partial wound dehiscences and one postoperative hematoma at the donor site. Seventeen flaps survived completely. Secondary thinning procedures were not required. CONCLUSIONS: The serratus carpaccio flap is an excellent option for the reconstruction of medium-sized skin and soft tissue defects of the dorsum of the hand or foot, the palm, and the distal forearm.
