Abstract:

The deep inferior epigastric perforator flap（DIEP）is a perforator flap supplied by deep inferior epigastric artery. This flap contains only cutaneous and subcutaneous tissue without damaging the integrity of rectus abdominis and the sheath. Thus，compared with transverse rectus abdominis muscle flap，the DIEP can overcome the shortage of bulky tissue volume and reduce donor site complications. So it has become more and more popular clinically. For the advantages of providing large volume tissue，reliable blood supply and minor complications，the DIEP has been widely used for reconstruction of oral and maxillofacial defect. It is now a reliable choice for oral and maxillofacial reconstruction，especially for extensive defects.

Key words: deep inferior epigastric perforator flap, DIEP；oral and maxillofacial defects；reconstruction

摘要：

腹壁下动脉穿支皮瓣（DIEP）是一种以腹壁下动脉为血供来源的穿支皮瓣，仅包含下腹部皮肤和皮下组织，不破坏腹直肌及前鞘结构。与传统的腹直肌皮瓣相比，DIEP克服了皮瓣臃肿的缺点，减少了并发症的发生，因此在临床得以推广普及。由于具有组织量大、血供可靠、并发症少等优势，近年来，DIEP被越来越多地应用于口腔颌面部缺损的修复重建中，尤其对于大型口腔颌面部缺损，该皮瓣是一种可靠的选择。
