Objective To investigate the clinical curative effect of titanium microplate to repair and fix obsolete cracky orbital fracture.Methods According to the diagnosis of CT scanning and three-dimensional imaging, 20 cases of obsolete orbital fractures were repaired and fixed by using titanium microplate along fracture lines. The microplates were placed according to the part nad shape of fractures. For the part of comminuted fractures, the two ends of fractures were fixed like a bridge. Results After the repair and fixation of titanium microplate, facial deformity became recuperative completely, eye-ball-movement and mastication function were recovered. During 6~12 months follow-up period, no reject reaction or cracking or dropping of microplate occured.Conclusions The titanium microplate can make orbital fractures rigid and internal fixed, and the procedure is simple and easy mastered. Therefore, it is one of the most effective materials in the repair and fixation of orbital and facial fractures.
