Triple Dufourmentel hexagonal flap for scalp reconstruction

Abstract

How to close scalp defects is one of the challenges a surgeon often faces in his daily clinical practice. Transposition flaps are some of the most commonly used flaps in this location.In cases where large surgical defects need to be closed, we may have to use a combination of several flaps because the scalp has limited mobility.The combination of three Dufourmentel flaps to close defects of hexagonal morphology is a useful option in the scalp but could also be applied in other anatomical areas. | E XPERIMENTAL DE S IG N AND RE SULTSA 70-year-old male patient was presented with a 2.5 × 2.5 cm vertex squamous cell carcinoma. Hexagonal flap was designed by drawing a hexagon around the lesion and three Dufourmentel flaps as shown in Figure 1 and Figure 2A.After designing the flap in the patient (Figure 2A), the tumour and the perilesional area was infiltrated with tumescent local anaesthesia. This anaesthetic solution is obtained by mixing 20 mL of mepivacaine 2%, 20 mL of physiological saline 0.9% and 0.1 mL of adrenaline 1%. The use of tumescent anaesthesia with vasoconstrictor favours
