腹股沟皮瓣是临床开发最早的游离皮瓣之一，但因解剖位置不恒定，变异较多，后临床应用逐渐减少。随着显微外科技术发展，近十年来，其在颌面外科和显微外科的临床应用逐渐增多。为了促进腹股沟皮瓣的推广及发展，本文就腹股沟皮瓣及其穿支皮瓣的解剖、各种形式的设计、适应证、手术方法及其优点和缺点进行讲述，侧重介绍其在四肢软组织缺损的应用。“,”Groin flap is one of the earliest free flaps in clinic, but its clinical application reduced gradually due to its unstable anatomical position and many variations. With the development of microsurgery techniques, the clinical application in maxillofacial surgery and extremities trauma has gradually increased over last decade. In order to promote the popularization and development of groin flap, this paper focuses on the anatomy, indications, advan- tages, disadvantages, various forms of design and methods of operation of groin flap and perforator flap, especially the application in the skin and soft tissue defects of limbs.
