Reconstruction of maxillectomy defects using deep circumflex iliac artery–based composite free flap

Abstract

Reconstruction of maxillectomy defects is a challenging endeavor, and various methods have been described to rehabilitate these defects, out of which composite free tissue transfer has an established role in reconstruction of the maxillary defects. The deep circumflex iliac artery (DCIA) flap has distinct advantages regarding the volume and length of the bone in reconstruction. The contour of the iliac bone is similar to the maxilla and provides good esthetic result. Good volume of bone allows placement of osseointegrated implant for dental rehabilitation. We present 8 cases of maxilla reconstruction using DCIA flap (3 osteocutaneous and 5 osseous flaps) for benign and malignant pathologies of the maxilla. DCIA flap is difficult to harvest, has variable anatomy, and needs meticulous planning for optimum result.
