A New Option to Preserve Esthetics in Perioral Defect Reconstruction With Normal Anatomical Structures: Bipedicled...

Plastic surgeons charged with reconstructing extensive perioral defects face dual challenges of functional restoration and esthetic considerations. While forehead flaps are commonly used to reconstruct perioral defects, in cases involving partial upper lip defects where normal anatomical structures are preserved, traditional forehead flaps may compromise esthetics. This study aimed to address this issue by employing bipedicled preexpanded forehead flaps based on the frontal branches of the superficial temporal artery (hereafter, "STA-bfb-based preexpanded forehead flap") with random flap extensions to repair perioral defects. Between April 2004 and July 2020, 7 patients (5 males and 2 females; 6 had post-burn facial scars involving the entire lower lip and part of the upper lip, and 1 presented with noma sequelae) underwent perioral defect reconstruction using this approach. Tissue expanders were placed in the forehead donor area, and an STA-bfb-based preexpanded forehead flap with random flap extensions was used to repair the perioral defect. The flap pedicle was divided into 3 weeks. All flaps remained viable with no perfusion-related complications. At follow-up 12 to 96 months later, the color and texture of the flaps demonstrated excellent compatibility with the surrounding skin, suggesting that the use of an STA-bfb-based preexpanded forehead flap with random skin flap extensions is a reliable method for repairing perioral defects. The authors' results have implications for plastic surgeons seeking a solution for challenging perioral defect reconstructions, balancing the need for esthetic outcomes with functional restoration.
