  • Title: Reconstruction of burn contractures of the anterior neck with pre-expanded free anterolateral thigh flaps.
    Author: Acartürk TO, Bengür FB.
    Journal: Injury; 2020 Dec; 51 Suppl 4():S63-S67. PubMed ID: 32122624.
    Abstract:
    Burn contractures of the anterior neck result in severe functional and aesthetic deformities. The release of wide contractures leads to defects that cannot be closed with local flaps. In these cases, tissue expansion of local tissues may be a solution. However, when local tissues are also burned or inadequate, microsurgical free tissue transfer may be necessary. In order to increase the surface are of the transferred flap, pre-expansion of the donor site can be combined with the procedure. Five patients with burn contractures of the anterior neck were treated using pre-expanded free anterolateral thigh (ALT) perforator flaps. The anterolateral thigh was dissected on top of the fascia lata in an avascular plane. The borders of the dissection were kept 2 cm lateral to the pre-identified perforators. A 1000cc rectangular tissue expander was placed. The time of expansion ranged from 4-11 months with a final over expanded volume of 1200cc. The defect sizes ranged from 10 × 21 cm to 20 × 27 cm. There were either one or two perforators included in the flaps. All flaps survived completely with good functional and aesthetic outcomes. Donor areas were closed primarily in one patient and with various amounts of skin grafts in five patients. Overall, pre-expansion decreased the amount of total skin grafted area in the donor site. Pre-expanded ALT perforator flap can be a good option in extensive burns with wide contractures where the regional donor areas are also affected. This technique has several advantages: 1) large flaps can be safely harvested, 2) the expanded skin thins out making it more aesthetically appropriate to resurface superficial defects, 3) expansion period of the thigh is well tolerated by the patients, 4) two teams can work simultaneously, decreasing the operating time, 5) the donor area can be closed either primarily or with minimal skin graft application, and 6) there is no functional loss in the donor area and the donor scar stays under the clothes.
