Abstract
Since 1978, 35 patients have undergone mandibular reconstruction with vascularized iliac crest. During this time, the technique of raising and shaping the iliac crest has undergone a series of modifications. Initially, osteocutaneous segments based first on the superficial circumflex iliac system and later on the deep circumflex iliac system were used. More recently, only the inner table of the ilium has been employed, and where intraoral lining is required, an ulnar forearm free flap has been added. Thirty-two patients were reconstructed successfully. Of the three anastomotic failures, one bony segment was able to survive as a free graft. There were no donor-site complications. With continued experience, operative morbidity has been minimized, while the technique has been modified to tailor the reconstruction to the specific requirements of the patient. It is concluded that vascularized iliac crest provides the most appropriate mandibular reconstruction for a range of congenital and acquired defects.
