Abstract

Abstract: PURPOSE: To evaluate the feasibility and effect of 3D printing design and endoscope in reduction and fixation of fractures of zygoma and zygomatic arch. METHODS: Four patients diagnosed as B type fractures of zygoma and zygomatic arch with limited mouth opening and facial depression were included. After CT scanning data were tranformed into STL type, the fracture model and mirror-imaged model were printed. Preoperative design and premolding of titanium plates were completed on the models. Through a small preauricular incision and tunnel on the zygomatic arch, reduction and fixation of fractures of zygoma and zygomatic arch were performed under endoscope. RESUITS: All patients achieved symmetrical face and normal mouth opening. Facial scar was not obvious and there was no complication such as infection and nerve damages. CONCLUSIONS: 3D printing design reduces the difficulty of endoscopic surgery in reduction and fixation of fractures of zygoma and zygomatic arch and improves the precision of operation. This method avoided coronal incision and achieved cosmetic results with minimal invasion.
