The palm is of great importance for maintaining a functioning hand. The reconstructive demands of thickness, texture, color matching, pliability, and sensation for palmar defects represent a unique challenge for plastic surgeons. This study introduced a novel versatile design for the ulnar palmar artery perforator flap (UPAPF) to cover large palmar soft-tissue defects of the hand. The fifth metacarpophalangeal joint was identified as a landmark where the perforator was nearly 1 to 1.5 cm proximal. A template of the defect was outlined after adequate debridement. Meticulous dissection was executed under loupe magnification to trace the perforator until an adequate length of the pedicle was obtained for rotation. The harvested type B fasciocutaneous flap was rotated nearly 90° to be insetting on the palmar defect. Two patients were presented with a soft-tissue defect of the palm measuring 4.8 × 5.5 cm
