Objective To investigate the clinical effect of individual prefabricated reconstructive titanic plate combined with vascularized iliac bone-muscular flap for reconstruction of mandibular defects.
Methods: From Aug.2010 to Dec.2014,12 cases with mandibular tumor received preoperative maxillofacial CT scans and 3-dimensional reconstruction. Based on the CT results, mirror imaging technology was used to simulate the reconstruction of the defect at affected side. The individual reconstructive titanium plate was prefabricated on the model. The iliac bone-muscular flap was designed according to the defect shape and size, combined with reconstructive plate. All patients underwent CT scan and oral curved surface tomography postoperatively. The maxillofacial function and appearance were also evaluated.
Results: According to the CT scan and curved surface tomography, the 12 iliac bone-muscular flaps survived completely with good bone union and good condyle position. Both the functional and cosmetic results were satisfactory. There was no complication on the donor sites.
Conclusions: Individual prefabricated reconstructive titanic plate combined with vascularized iliac bone-muscular flap provides an precise method for reconstruction of mandibular defects. The cosmetic and functional results could be expected.
