    Abstract:
    In this study, the authors' aims were to measure the length and location of branching of the pedicle from iliac artery, to describe the anatomical variability of iliac crest free flap with deep circumflex iliac (DCI) artery pedicle. Fourteen patients with ameloblastoma, osteosarcoma, and squamous cell carcinoma underwent mandibular resection and iliac crest-free flap reconstruction in one-step surgery. During surgery and before harvesting the deep circumflex iliac artery vascular pedicle, the location, origin, and the branching pattern of the pedicles were studied. Then, the pedicle length was measured and the data was analyzed using χ and independent samples t test. In all patients, the DCI vascular pedicles were separated with a common trunk from the external iliac artery and vein and the DCI arteries were posterior and lateral to the veins. Also after branching from the external iliac artery, all vascular DCI pedicles traveled upward and medially along the Iliacus muscle and the iliac fascia. The mean pedicle length was 21.78 mm for men and 19 mm for women. No statistically significant relationship was observed between the patient's age and the vascular pedicle length or number of branches. There are great variations in the anatomy of this vascular pedicle. According to the finding of this study, the length of the vascular pedicle is 2.78 mm higher in men which might help to increase the feasibility and success rate of this operation. No significant correlation was found between other variables.
