Orbital floor injuries, alone or in combination with other facial fractures, are one of the most commonly encountered midfacial fractures. Significant complications can occur as a result of these injuries, including enophthalmos, persistent diplopia, vertical dystopia and restriction of gaze. Appropriate repair is therefore critical. There is currently a greater understanding of the complex anatomy of the orbit and changes that occur within the orbit from disruption of its contents caused by trauma. Although many biomaterials are available to reconstruct these deformities but the choice of material to be used remains controversial. This review aims to give a comprehensive review of the advantages and disadvantages of biomaterials used in post-traumatic internal orbital reconstruction, with the goal of assisting surgeons to make a better choice Key words: Biomaterials, Traumatic
