Application of the Expanded Neck Flap for Face and Ear Reconstruction in Burn Patients: A Report on 2 Cases.

Reconstruction of auricular deformities and facial scars after burns is a challenging undertaking for surgeons. Excessive scar tissue, a poor blood supply and the paucity of available skin are all substantial difficulties that should be considered before the operation. Expanded neck flaps provide comparatively larger and thinner flaps for the simultaneous treatment of auricular deformities and facial scars in burn patients. In this article, the authors introduced the use of an expanded neck flap as coverage tissue for ear reconstruction and face resurfacing in 2 burn patients. The operation consisted of 3 stages. In the first stage, the expander was implanted subcutaneously under the skin of the neck to create adequate skin and soft tissue. In the second stage, the expander was removed, and the expanded flap was transferred to cover defects on the auricle and face. The third operation to repair the reconstructed ear and thick flap could be performed according the willingness of the patients and surgeons. Esthetically satisfactory results were achieved in both of the patients. The flaps survived completely, and the skin color, texture, and flexibility were well matched to those of the peripheral tissue. Six months postoperatively, the flaps did not shrink, and subsequent contractures did not recur. Both of the patients experienced high satisfaction, and no adverse effects were detected.
