[The application of deltopectoral flaps with delayed expansion in repairing large scars on face].

ABSTRACT

OBJECTIVE: To evaluate the effect of use of deltopectoral flaps with delayed expansion in repairing large scar on face. METHODS: Thirteen patients with large scars on face received above-mentioned surgery. The cutaneous branches of thoracoacromial artery and transverse cervical artery of patients were divided when the expander was implanted. As a result, the blood supply of expanded deltopectoral flaps principally depended on the second and third intercostal branches of internal thoracic artery, and a delaying effect was achieved. The distribution of vascular net in the flap and the state of blood supply of the flap were observed to evaluate the effect of delaying. RESULTS: The vascular net of expanded flap increased and thickened. No blood supply disorder occurred at the distal end of the transferred flap. Patients were followed up for 4 to 18 months. The outline of the burn side of face was in accord with the opposite side, which was not fat and clumsy. The complexion of the flap was similar to that of normal skin of the face, and the flap was soft in texture. CONCLUSIONS: The application of delaying can better ensure the blood supply of transferred deltopectoral flap. The result of applying delayed expansion of deltopectoral flaps in repairing large scars on face was good.
