Abstract:
To evaluate the clinical effect of digital assisted chimeric deep circumflex iliac artery perforator flap (DCIAPF) in the reconstruction of mandibular composite defects. Methods From January, 2018 to January, 2019, 6 cases of mandibular tumor patients with postoperative defect within side were treated. Preoperative CTA was used to evaluate the deep branches of spin iliac artery.Digital simulation software and 3D printing technolo-gy was taken, vascularized iliac flap of the design guide of bone was made, and the rebuilding effect was simulated. DCIAPF was used to repair the defect of lower jawbone. The donor sites were sutured directly. The patients were fol-lowed-up in outpatient department for 3-6 months to evaluate the recovery of the patient′s shape, jaw height and oc-clusal function, as well as the complications in the donor area. Results Postoperation pathological examination re-sults: ameloblastoma in 2 cases, 4 cases of gingival cancer. The length of cut out ilium was 6.0-13.0 cm, carrying the flap area of 3.0 cm×1.0 cm-6.0 cm×5.0 cm.Six cases of DCIAPF and iliac bone flap survived.The shape, mandibular height and occlusal function were satisfactory.And no obvious complications were found in the donor area. Conclu-sion The blood supply of DCIAPF is rich with enough bone mass and height. The position of terminal skin perfora-tors is invariant. The complications of donor sites is less. With the help of digital technology, the accuracy of mandibular defect repair and the 3-dimensional wound repair can be realized, and provides an advantage condition for subsequent dental implant.It is one of the ideal method of reconstruction of mandibular defect.
