Keystone design perforator island flap in facial defect reconstruction

Figure 5 A 67-year-old woman was diagnosed with basal cell carcinoma on the nose after a punch biopsy. There were two lesions in the right dorsal subunit and the left alar side wall subunit of the nasal unit. A: She underwent wide excision of each lesion with a 3-mm safety margin, and each final defect was measured to be 1.8 cm x 1.8 cm on the right side and 1.5 cm x 1.5 cm on the left side; B, C: We covered defects with each Ω-variant Type IIA keystone design perforator island flap (flap size: 3.5 cm × 5 cm) on the right side and a Ω-variant Type IIA keystone design perforator island flap (flap size: 2 cm × 3.5 cm) on the left side. Final suture lines were located within and along each facial subunit; D: Postoperative clinical photograph after 12 mo.
