Area of Science:

Oral and Maxillofacial Surgery
Medical Imaging
Computer-Aided Surgery

Background:

Facial symmetry reconstruction is enhanced by virtual environment computer-modeling software.
Maxillofacial skeleton reconstruction presents complex challenges in traumatic deformities.

Observation:

Three patients with traumatic maxillofacial deformities underwent CT scans.
3D reconstructions and virtual osteotomies were performed using MIMICS software.
Virtual datasets guided intraoperative navigation for surgical repair.

Findings:

Excellent correction of enophthalmos (patient 1).
Significant improvement in nasoethmoid complex symmetry (patient 2).
Accurate zygomaticomaxillary complex reconstruction within 1 mm (patient 3).
