Keystone design perforator island flap in facial defect reconstruction

Figure 8 A 65-year-old man was diagnosed with basal cell carcinoma on the right medial canthal area after a punch biopsy. A: The lesion was located on the medial canthal subunit and lower-lid subunit of the right eyelid unit; B: He underwent wide excision of the lesion with a 4-mm safety margin, the final defect was measured to be 1.8 cm × 2.5 cm; C, D: We covered the defect with a Ω-variant Type IIA keystone design perforator island flap (flap size: 2.5 cm × 6 cm) from the right dorsal subunit and dorsal side wall subunit of the nasal unit. Final suture lines were located within and along each facial subunit; E, F: Postoperative clinical photograph after 6 mo.
