Treatment of complex orbital fractures and orbital malformations

  Orbital fractures include burst orbital fractures and compound orbital fractures. Even in simple burst orbital fractures, if the orbital wall defect is large (greater than or equal to 4 cm2), deep (greater than or equal to 3 cm), and the inner and lower walls are fractured at the same time, the results of traditional treatment methods are not very satisfactory and sometimes even impossible to perform. The reason for this is the lack of effective support and fixation of the orbital implant in traditional fracture treatment, and the difficulty in achieving precise orbital anatomical reconstruction with simple intraoperative processing of the orbital implant, as well as the difficulty in ensuring that the orbital implant is placed in the correct position intraoperatively.  More severe compound orbital fractures not only have a large fracture defect in the orbital wall, but also have a defect or displacement of the periorbital bone and a deformity that is difficult to treat with conventional methods. More severe orbital malformations include congenital orbital malformations and acquired orbital malformations, for which there is no effective conventional treatment.  For complex orbital fractures and orbital malformations, successful treatment is possible with the development of computer technology, material technology and medical imaging image processing techniques. Based on detailed CT data, the three-dimensional shaped titanium mesh to be implanted can be individually prefabricated, allowing for preoperative surgical design and simulation, and can be accurately positioned intraoperatively, resulting in precise reconstruction of the orbital anatomy, which is particularly suitable for the treatment of complex orbital fractures and orbital malformations.
