Abstract:
Objective To summary the application of computer aided three-dimensional visualization technique in different kinds of mandibular detects reconstruction with vascularized free fibular flap.Methods Five patients diagnosed of recurrent mandibular ameloblastoma underwent the virtually operation by software with a thin-slice CT scan,which determined shape and position of the free flap,and preoperative resin model and modules were designed and prefabricated.Then the titanium plates were bent precisely,and the surgical reconstruction proceeded exactly as expected from the modeling process.Results All operations were achieved successfully.The extent of the lesion was coincident with the preoperative CT results,and the vascularized free fibular flaps were harvested and implanted into the defect regions accurately.The mean distance was (0.23 ±2.10) mm compared with the virtual fibula.The mean time of operation was 4.4 hours.Following up the mean 12.8 months,all patients obtained the excellent functional and cosmetic outcomes.Conclusion The procedure of operation was simplified and the time was shortened with reconstruction exactly using computer aided three-dimensional visualization technique,and the clinical therapeutic efficacy of reconstruction of mandibular defect with vascularized free fibular flaps was improved notably.
