How to measure and judge the outcome of orbital fractures and orbital deformities? The best measure of treatment outcome should be the complete restoration of appearance and function. Theoretically, the key to the treatment of orbital fractures and orbital deformities is the precise reconstruction of the orbit and its surrounding anatomy (zygomatic bone, nasal bone, maxilla, and skull). The orbital anatomy is very complex, and the inner orbital surface has an irregular shape with many important sulci, fissures, and orifices, so its precise reconstruction is still a challenge for orbital disease and oculoplastics. With the development of computer-aided design and assisted fabrication technology and its application in the medical field, advances in medical imaging image processing software, and the advent of ultra-thin layer CT technology, precise orbital anatomical reconstruction has become possible. Titanium is generally chosen as the implant material, which has the characteristic of good histocompatibility and does not have the disadvantage that most of the previously used materials cannot be shaped preoperatively. The general process of this technique is as follows: 1, the individual patient’s ultrathin CT data is collected and burned; 2, the CT data is processed and corrected with special processing software, and the orbital model is reconstructed in three dimensions, for the left lower, inner wall fracture defect; 3, using the mirror image technique, the orbit of the uninjured normal side is replaced by the orbit of the injured orbital bone defect deformity on the other side, and the original image is merged with the mirror image, and the original fracture defect is seen to be simulated and repaired The orbital fracture defect was replaced by the normal side of the injured orbit using the rapid prototyping technique; 5. We have been applying this technique for the treatment of orbital fractures and orbital deformities since 2006, and have treated nearly 100 patients, successfully performing precise anatomical reconstruction of the orbit and periorbit, and achieving individualized treatment with good results.
