Objective:
The production of 3-dimensional models and materials according to preoperative virtual surgical planning is a time-consuming process and causes high costs. We aimed to demonstrate the navigation mediated reconstruction of the patients who underwent the removal of a tumoral mass in midfacial region according to their preoperatively prepared surgical plannings.
Study Design:
Patients who underwent the removal of tumoral mass and reconstruction in their midfacial region were included in the study. Virtual surgical planning was performed by the mirror imaging of the unaffected side of the maxillofacial bones. New created models were converted to Digital Imaging and Communications in Medicine (DICOM) data to use in the navigation system. Histogram analysis was performed to reveal the compatibility of navigation mediated reconstruction with preoperative virtual surgical planning.
Results:
Reconstruction of orbital floor was achieved in all of the cases. Histogram comparison of the localizations of orbital floor and maxillary walls was calculated at a confidence level of 95% (P > .95) and mean difference was found 0.85 mm; whereas the standard deviation was 3.55 mm.
Conclusion:
We found that virtually prepared reconstruction of midfacial area can be successfully adapted to the surgery with the assistance of an intraoperative navigation system. (Oral Surg Oral Med Oral Pathol Oral Radiol YEAR;VOL:page range).
