A combined superficial inferior epigastric artery flap and vascularized iliac crest flap in the reconstruction of extended composite defects of the posterior mandible and adjacent soft tissue: first clinical results

Abstract The technique of posterior facial reconstruction using a combination of a superficial inferior epigastric artery (SIEA) flap and a microvascular iliac crest flap (deep circumflex iliac artery (DCIA) flap) is described. 12 cases are reported. The patients had unilateral squamous cell carcinoma of the posterior mandible affecting parts of the soft palate and tonsil region or the posterior cheek. In all patients unilateral neck dissection, resection of the posterior and lateral mandible, was performed. Reconstruction was carried out during primary surgical therapy, followed by postoperative radiotherapy. A flap combination of a SIEA and a DCIA flap was used. There were no problems with pedicle length or anastomoses. There was no flap loss or severe postoperative complications. All patients had good aesthetic and functional results. One patient had distant metastases 2 years postoperatively. All other patients were free of tumour relapse or metastases within 12–58 months of follow up. The SIEA flap and vascularized iliac bone flap combination is useful in reconstructing the posterior face. The iliac bone flap is well suited for posterior mandible reconstruction and the SIEA flap for reconstruction of the soft palate, lateral pharyngeal wall and cheek. Both flaps are harvested from the same donor site.
