BackgroundLocal flap surgery is commonly performed to cover defects with appropriate skin color and texture match. The purpose of this study was to present an algorithm for choosing an appropriate flap when reconstructing a midface defect using a local flap.MethodsBetween February 2013 and February 2019, 38 patients with midface defects underwent local flap surgery. All defects larger than 3 cm in diameter were reconstructed with perforator-based transposition flaps. Defects smaller than 3 cm in diameter were reconstructed differently depending on their location. Defects near the nasolabial fold (NLF) were reconstructed with perforator-based transposition flaps, whereas defects just on the NLF were reconstructed with VY advancement flaps. Defects distant from the NLF were also reconstructed with VY advancement flaps.ResultsPerforator-based transposition flaps were used in 22 cases and VY advancement flaps were used in 16 cases according to our new algorithm. All flaps survived without any complications. The aesthetic results were superior for VY advancement flaps, with higher patient satisfaction scores. The skin color match was similar for both flaps, but the contour was more natural in advancement flaps than in transposition flaps. However, transposition flaps had the benefits of being able to cover relatively large defects and allowing the donor scar to be hidden in a wrinkle line.ConclusionThe most suitable local flap for coverage of a midface defect can be chosen based on the patient's condition. By following our algorithm, appropriate reconstructions can be performed, with satisfactory results.
