ABSTRACT

Orbital fractures are common facial injuries that usually occur in patients diagnosed with zygomatic-orbital fractures and can be classified as pure blow-out fractures or be part of panfacial injuries. Orbital wall fractures occur through the two main mechanisms, by impact on the soft tissues and impact on the solid structures of the orbital wall. Medial orbital wall fractures usually involve the lamina papyracea of the ethmoid bone, which is the largest and thinnest component, and is responsible for the most vulnerable part of the medial wall of the orbit. Therefore, these fractures are affected by a combination of increased intra-orbital pressure and dissipated force from the medial orbital rim. For the treatment of large orbital fractures, a coronal approach along with local incisions becomes necessary and it is unquestionable to use these surgical approaches to expose the fracture lines and subsequently define the reconstruction sequence. The reason that titanium mesh has provided better results in reconstructions is due to the ease with which the mesh can be shaped to fit the intricate contours of the internal orbit. This paper aims to describe a series of three clinical cases of orbital reconstruction, mainly roof and medial wall fractures of the orbit reconstructed using titanium mesh and to address the possible complications in this type of treatment.
