Recently, the head and neck surgery of Gansu Provincial Cancer Hospital took the lead in the province to use computer-aided design and 3D printing technology to successfully perform right mandibular tumor resection and titanium plate internal fixation reconstruction surgery for a 28-year-old female patient.
Before surgery, the doctor generates a virtual model of the lesion and the contralateral mirror through the surgical planning system, and reconstructs the normal mandibular shape of the patient with the mirror image of the mandible and the computer-aided design. The 3D printing technology is used to make 1:1 rapid prototyping and actual hard. A consistent physical model, preoperative design of the osteotomy area, can refer to the mandible mirror model, measure the length of the reconstructed titanium plate and complete the shaping of the titanium plate, pre-bending the titanium plate to make it fit completely on the surface of the model, determine Fix the position of the screws to achieve the desired fit.
This surgery uses computer-aided design and 3D printing technology to visually display the shape of the jaw and tumor, making it easy for doctors to complete the surgical design. Surgery was performed strictly according to the preoperative plan during the operation. The operation was smooth and the operation time was shortened by half. The postoperative results were good. After tracking, the patients recovered well in terms of facial morphology, occlusion recovery, joint function, and mouth opening.
