Scalp Defect Reconstruction Using the Ying-Yang Double Rotation Flap: A Case Report

Scalp reconstruction represents a surgical challenge due to the limited distensibility of tissues and the aesthetic importance of the hair-bearing unit. The ying-yang flap is a double rotation technique designed to optimize defect coverage without resorting to grafts, and the objective of this report is to demonstrate its versatility and efficacy in scalp reconstruction. We present the case of a male patient in his sixties with a lesion secondary to basal cell carcinoma measuring approximately 5 cm in diameter. Following resection, a deep circular defect with exposed pericranium was created. A ying-yang flap technique was performed to achieve a tension-free closure. The postoperative period was uneventful, with preservation of hair density and absence of vascular complications. In conclusion, the ying-yang flap is a versatile and reliable technique that minimizes tissue tension and offers superior aesthetic results in this anatomical region.
