Abstract
OBJECTIVE: To explore the aesthetic reconstruction strategy for postburn facial scar and its clinical effect.
METHODS: Three hundred and forty-two patients with postburn facial scars were hospitalized from January 2000 to December 2015. Local expanded flap or deltopectoral expanded flap was used for reconstruction according to the location and size of the facial scar. The forehead expanded flap could be chosen for the scar in dorsum nasi or inferior eyelid. The local expanded flap was chosen when the scar width was smaller than 5 cm in cheek, chin, and marginal mandible region. The expanded deltopectoral flap was chosen when the scar width was larger than 5 cm in cheek, chin, and marginal mandible region or the scar contracture was too serious to cause displacement of lips, nose, or eyelid, and the wound width was larger than 5 cm after release. The facial scars of 82 patients, with size ranged from 6.0 cm×2.5 cm to 15.0 cm×10.0 cm, were reconstructed with expanded local flaps. The facial scars of 260 patients, with size ranged from 8.0 cm×7.0 cm to 38.0 cm×13.0 cm, were reconstructed with expanded deltopectoral flaps. After expansion of 2 to 6 months, the facial scars were excised and completely released first of all. The transfer way of local flap and size of deltopectoral flap with pedicle were designed according to the size and shape of the wound. Three weeks after transfer of deltopectoral flap, flap delay procedure was conducted. One week later, the pedicle was severed from the flap to reconstruct the remaining scar. Anti-scar medicine, laser therapy, and elasticized fabric were used postoperatively on the scars in both donor and recipient sites.
RESULTS: During the postoperative follow-up for 3 to 12 months, the flaps of 40 out of 82 cases reconstructed with expanded local flaps were in good color and texture. Before 2008, mild scar hyperplasia was observed in the incision of 19 patients; with application of laser after 2008, the number of patients with scar hyperplasia was decreased. During the postoperative follow-up for 3 to 12 months, the flaps of 90 out of 260 cases reconstructed with expanded deltopectoral flaps were in good color and texture. The expander was exposed from the incision in 15 patients, while it did not affect the later treatment. Nine unilateral flaps showed poor blood circulation at the distal end, and they were healed after dressing change. In the early phase, necrosis was observed in one flap after transfer, and it was healed after transplantation of free skin graft. Scar hyperplasia was observed in the chest donor site of one patient, and it was improved after laser therapy.
CONCLUSIONS: Postburn facial scar could be reconstructed with local or deltopectoral flaps, following the principle of similarity. The expansion could increase the size of the flaps, reduce the thickness of the flaps, and lower the donor site damage.
