|
Purpose: Fibular osteocutaneous free flap is the procedure of choice for mandibular reconstruction. However, the anatomic consistency and the reliability of the skin paddle have been considered to be questionable and the utilization of the fibular osteocutaneous free flap can be challenging for the inexperienced surgeon. Preoperative computed tomography (CT) angiography can support revolutionary help with the operator design of the fibular osteocutaneous flap. The purpose of this article is to share the valuable experience of support with preoperative CT angiography.
Methods: Three consecutive patients, who needed mandibular reconstruction, were treated with fibular osteocutaneous free flap. Each of the patients had undergone lower extremity CT angiography before the surgery. The CT angiographies were scrupulously investigated to calculate the locations and the tracts of the peroneal artery perforators. We compared the findings of the CT angiography with those of the real operation.
Results:The information about the perforators was sufficiently matched with the findings of the operation. With the use of preoperative CT angiography, we were able to achieve confident performance during operation, shortening of operation time, and fine outcomes with a no flap failure.
Conclusion:The CT angiography of lower extremity can provide reliable information of the perforators of the fibular osteocutaneous free flap.
