Application of Modified Triangular Perforator Flap in Repair of Small and Medium-Sized Facial Defect

BACKGROUND: We investigated the application of local perforator flap or island flap with a modified triangular to repair small and medium facial defects. METHODS: (1) Before the operation, a Doppler flowmeter was used to investigate the superficial exit point of the perforator artery. The length to breadth ratio of the flap was more than 3–4 times, and it contained 1–2 perforator vessels. (2) The lesion was excised, and the skin was cut along the design line of the flap. The flap was separated and trimmed based on the defect degree. (3) The blood supply was confirmed, and the defect was then covered with the flap by “rotation and advancement” approach without causing tension. The incision was finally sutured in layers. (4) Postoperative routine care was performed according to the situation. RESULTS: The functional morphology and appearance of all 23 cases of skin flaps successfully recovered during follow-up. There was no major aesthetic and malformation recorded. CONCLUSION: In summary, the modified triangular perforator flap can improve the functional appearance at the repaired small and medium facial defects.
