Abstract:
Objective:To explore the application of the 3D precise digital technology in restoring structural defects of the orbital region.
Methods:Structural defects of the orbital region concerning on osseous structure and soft tissue were restored in one stage or stages using EH composite artificial bone prosthesis with complex three-dimensional structure. The fabrication of EH composite artificial bone prosthesis was based on CT scanning and 3D reconstruction of the skull with computer aided data analysis and design. The appearance, degree of satisfaction and the complications were evaluated in postoperative regular follow-up.
Results:Five cases of structural defects in the orbital regions presenting bone defect and soft tissue abnormality, received treatments in the department from January 2016 to September 2017. The cases consist of one patient with dysplasia following surgical treatment, three with post-traumatic and one with Treacher-Collins syndrome. With the application of individualized EH composite artificial bone fabricated by aforementioned method, all the repair materials presented the ideal three-dimensional structure and coincided well with the defects, and soft tissue restoration of 2 cases was performed in one stage or by stages. Appearance and symmetry of the 5 cases was significantly improved, without complications of infection, rejection, exposure or graft tissue necrosis. All the patients were satisfied with the results.
Conclusions:In consideration of the capacity to fabricate accurate individualized repair materials, the three-dimensional digital technology plays an important role in the treatment of structural defects in the orbital region, especially the reconstruction of the bony contour. The simple orbital deformities can be treated with the repair materials and correction of soft tissue. For special orbital deformities, attention should be paid to bone structure repair, eye socket reconstruction and filling of orbital contents sequentially.
