Abstract Objective To discuss the feasibility of 3D printing guide plate used for titanium mesh pre-forming in orbital surgery and observe its preliminary effect. Methods From January 2013 to December 2015, 20 patients (20 eyes) underwent orbital fracture surgery in the Second Hospital of Hebei Medical University were enrolled in the study. Preoperative eyeball invagination was greater than 3 mm. All the patients underwent spiral CT scan before operation. The data were reconstructed by Mimics software, and then the images were repaired by computer aided design. The subtraction operation in the Boolean operation of the software was applied, and the original defect orbital wall data were subtracted from the repaired image. 3D printing guide plate was used for titanium mesh pre-forming in orbital surgery. Visual acuity, exophthalmos and diplopia were observed after operation to evaluate the effect. Results No visual acuity was reduced at 6 months post surgery in the 20 patients, the difference of the protrusion of the eyes were equal to or less than 2 mm in 17 patients, diplopia disappeared in 11 patients at 6 months post operation. The 3D printing guide plate helped to achieve more precise anastomosis between titanium mesh and orbital defect area, and reduced the time required for titanium mesh formation in operation. Conclusion The individualized surgical guide plate can be used for 3D pre-forming of titanium mesh, which is helpful to improve the accuracy of operation and reduce the operation time.
