Orbital fracture repair by computer-assisted intraoperative navigation

Introduction: Reconstruction of orbital wall fracture is done to restore bony contour of the orbit out of functional reason and also to avoid development of an enophthalmos. By improvement of the diagnostic and preoperative planning tools for these fractures, there is still a gap between planning and intraoperative implementation of the implant. We analyzed the benefit of intraoperative navigation in orbital fracture repair.

Material and methods: Fractures of the orbital floor and/or medial wall were reconstructed with prebended titanium meshes in 15 patients. 10 patients were operated by controlling of implant position with a computer-assisted navigation system, 5 patients were operated without this guidance out of not available of the navigation system.

Results: Implant correction was necessary in 3 of the 5 patients without navigation control out of functional disturbances. There was no revision in the 10 other patients. An intraoperative CT scan was not available in all of the patients.

Conclusion: If a prebended titanium mesh is inserted in complex orbital fractures for reconstruction of the orbital walls, there would be an intraoperative control of the position of the implant useful. Intraoperative navigation allows to control implant position without additional radiation and seems a useful tool in complex fractures to reduce the complication rate and improve the outcome of these fractures.
