Deep circumflex iliac artery perforator flap with iliac crest for oromandibular reconstruction

When combined with iliac bone, perforator flaps are more chimeric, and there is increased mobile skin island to reconstruct soft tissue defects in the oral and maxillofacial region. This study examined oromandibular defects reconstructed using deep circumflex iliac artery perforator flap with iliac crest (DCIAPF). We retrospectively reviewed records of 23 patients with mandibular defects received DCIAPFs after oncological resection for oromandibular reconstruction from November 2015 to August 2016. All perforators, identified before surgery by Doppler examination, were terminal perforators of DCIA. DCIAPFs were successfully harvested in all patients. The flap survival rate was 95.6% (22/23); one flap failed due to artery spasm. Three patients developed slight skinedge necrosis in the skin island. Anatomical reconstruction contour of the mandible and sufficient bone length and height were achieved, with no serious donor-site complications during the follow-up period. The results demonstrated that DCIAPF is a favorable single-flap option for oromandibular reconstruction after oncological resection with fewer donor-site complications because of its adequate bone tissue and satisfactory soft tissue, with a constant location of the perforator.
