Keystone design perforator island flap in facial defect reconstruction

Figure 6 A 62-year-old man was diagnosed with basal cell carcinoma on the nose (dorsal subunit of the nasal unit) after a punch biopsy. A: He underwent wide excision with a 4-mm safety margin, and the final defect was measured to be 3 cm × 2.5 cm; B: We covered the defect with bilateral Ω-variant keystone-designed perforator island flaps (each flap size was 1.5 cm × 3.5 cm) from both dorsal side wall subunits; C: Postoperative clinical photograph after 1 mo of follow-up; D: Postoperative clinical photograph after 12 mo of follow-up.
