The deep circumflex iliac artery perforator flap (DCIAP)--a reconstructive option for the large composite...

The deep circumflex iliac artery (DCIA) flap is often used for mandibular reconstruction but it is bulky and causes additional donor-site morbidity because of the inclusion of an "obligatory internal oblique muscle". Large composite segmental mandibular resections that consist of floor of mouth, subtotal tongue, and adjacent facial skin are a challenge in terms of reconstruction. They often require 2 free flaps or a free scapular flap and both have disadvantages. The deep circumflex iliac artery perforator (DCIAP) flap with a cutaneous component overcomes the disadvantages. We describe reconstructions with DCIAP flaps in 3 patients with large mandibular composite segmental defects. We report our experience of the flap and discuss some of the difficulties we encountered and the points we learned perioperatively.
