- W4386466445 abstract "Wide local excision of noninvasive malignant melanomas has been increasingly performed instead of digit amputation, which often results in extensive fingertip defects. Owing to the unique anatomical characteristics of the fingertips, achieving favorable outcomes in both function and cosmesis is challenging during reconstruction. The free superficial palmar branch of the radial artery (SPBRA) flap is advantageous for finger reconstruction. However, its application in circumferential fingertip defects has rarely been reported. In this report, we describe two cases of circumferential fingertip defect reconstruction using a free SPBRA flap after wide local excision of subungual melanoma. The patients were women aged 74 and 63 years at the time of surgery. They presented with subungual melanoma on the right fourth finger and left thumb, in which both biopsies confirmed malignant melanoma in situ (Tis N0 M0), Breslow thickness of 0 mm (noninvasive). After wide local excision, circumferential defects, sized 2.5 × 6 and 2.7 × 7 cm, were formed on their fingertips. A vertically designed free SPBRA flap measuring 2.7 × 6 and 3 × 6 cm was elevated from the unaffected palm in each patient. After performing microvascular anastomosis, the flap was inserted transversely, wrapping the exposed phalangeal bone in a conical shape. The donor site was primarily closed. All flaps survived, and postoperative complications did not develop. Neither local recurrence nor distant metastasis was detected at the latest follow-up in either patient at 24 or 28 months postoperatively. The patients were satisfied with the natural contour of the reconstructed fingertip and recovered functions. In the evaluation of subjective sensory recovery using four scales (excellent, good, fair, and poor), they responded fair and good, respectively. We suggest that the free SPBRA flap could be a reliable reconstructive method for circumferential fingertip defects." @default.
