Using computer simulation and stereomodel for accurate mandibular reconstruction with vascularized iliac crest flap

Abstract

Objectives: The aim of this study was to examine our patients who underwent accurate mandibular reconstruction with vascularized iliac crest flap using computer simulation and stereomodel and assess the postoperative results.

Study design: Fourteen patients were reviewed in this study. Bilateral iliac crests were automatically superimposed on the mandibular defects to select the optimal matching donor region in computer simulation. Operation was performed using stereomodels to replicate the preoperative planning. Actual reconstruction result was compared with computer simulation. The patients were asked to assess their satisfaction with facial appearance at 1 year after surgery.

Results: Bony unions and good occlusion were observed, and actual results were basically in accordance with computer simulation in 14 patients. Fourteen patients reported their facial appearance to be excellent or good at 1 year after surgery.

Conclusions: Accurate mandibular reconstruction with vascularized iliac crest flap using computer simulation and stereomodel may achieve the ideal contour of neomandible and good function after dental rehabilitation.
