Orbital trauma are frequent complaint. Treatment aims to reconstruct defect, improve functional deficits and restore facial anatomy. Given its complexity and variability, the surgeon must take extreme caution in orbital management. In recent years has developed technology that allows us to precise orbital reconstructive procedures.

Aim : Describe three-dimensional surgical planning with models and intraoperative guides that support anatomical, functional and aesthetics results for patients with orbital trauma.

Methods : CT data stored in DICOM format. Planning was performed in 2D and 3D images and transfer to prototype models for optimization of surgical treatment. Additionally, were manufacture surgical repositioning guides and preformed plates and mesh. It proceed to surgery with transconjunctival extended with lateral canthotomy.

Results : Presents three-dimensional planning and transfer elements (model surgical guides and use of customize pre-bending mesh and plates) applied to the surgical treatment of orbital trauma. Benefits arising from use of this technology: decreased operative time, improved results and reduced learning curve.

Conclusions : Computer assisted three-dimensional planning with biomedical models is an option for treatment of orbital trauma. Its a valuable tool, providing better prognosis and quality of life for patient.
