Abstract

Background: One of the most frequent facial fractures is an orbital fracture, and multiple wall restoration is frequently required following high-energy trauma. Correct planning, thorough surgical dissection, and appropriate selection of the kind, size, and shape of the reconstruction material are all necessary for a successful outcome. The appropriate material to use to restore the orbital floor and walls is still up for debate. For that aim, numerous materials have been described from various sources. The ultimate goals involve treating the bony orbital deficiency while restoring anatomy, volume, function, and esthetics. While each type of material has benefits and drawbacks, the ability to fulfill those.
Aim of the study: This study evaluated the difference in the bone density after reconstruction of the orbital floor fracture with titanium mesh coated with natural nanohydroxyapatite by electrophoretic deposition versus conventional titanium mesh.
Patients & Methods: This study was conducted clinically on 12 adult patients with orbital floor fractures indicated for open reduction and internal fixation. The patients were divided into 2 groups, (group A): patients where the inaccuracies or reconstruction was done using the titanium mesh coated with hydroxyapatite nanocrystals and (group B): the repair and reconstruction of the defect was using conventional titanium mesh.
Results: There was a statistically significant difference in the bone density radiographically between the study and the control groups.
Conclusion: This study demonstrated better bone density outcomes in reconstructed orbital floor defects when compared to employing titanium mesh coated with nano-hydroxyapatite by electrophoretic deposition.
