Mandible Defect Reconstruction by Intraoral Anastomosis of Iliac Crest Bone Flap
Objective:To introduce the operation and advantages of intraoral vascular anastomosis technology com-bined with vascularized iliac crest flap transplantation in mandibular reconstruction during the era of digital surgery,and to explore the clinical application of intraoral vascular anastomosis technology.Methods:Three patients with benign tumors of jawbones who underwent jawbone resection and simultaneous repair in the Department of Oral and Maxillofacial Surgery,School of Stomatology,Wuhan University in 2022 were selected.Preoperative CT scans of the mandible and ilium were performed on the patients.Virtual surgical planning was made and osteotomy cutting guides were designed and produced.Tumors in two cases were resected through intraoral approach and in one case was resected through extra-oral approach.Iliac crest flap with pedicle was harvested.The facial artery and vein were used as recipient vessels to perform vascular anastomosis with the vascular pedicle of the iliac crest flap to recon-struct and repair the mandibular defect.Follow-up visits were conducted to evaluate the postoperative recovery of patients.Results:All three surgeries were successful.Two patients had no extraoral incision,and one patient had only extra-oral incision because of the primary lesion resection.Patients recovered well postoperatively.The man-dibular structure was basically symmetrical and aesthetic.Conclusion:The combination of intraoral anastomosis technology,iliac crest flap,and virtual surgical planning can achieve good postoperative results.Intraoral anastomo-sis technology can not only reconstruct mandibular lesions after intraoral resection,but also has certain advantages for cases requiring extra-oral approach to resect lesions.
