Abstract
Objective To discuss the applicability and application skills of lag screw in condylar intracapsular sagittal fracture and also to observe its therapeutic effect .Methods We conducted surgical reduction and rigid internal fixation to 21 patients with 27 sides of condylar intracapsular sagittal fracture in department of oral and maxillofacial surgery of the first affiliated hospital of chongqing medical university .Fixation of 24 sides were carried out with lag screw and and the rest sides had condylar bone fragment removal surgeries .Imaging data and clinical symptoms of each side were analyzed before and after the treatment .Results After postoperative follow‐ups in average 17 .4 months ,there were no facial paralysis ,salivary fistula and loose screws in 21 patients .Al‐so ,the recoveries of mouth opening degree and occlusal relationship were satisfactory .There were different degrees of temporoman‐dibular joint disturbances syndrome for the 3 patients with just 1 side done with condylar bone fragment removal surgeries and screw internal fixation before .Seven sides of patients had malocclusion and slight bone absorption in image inspection after surgery . However ,the functions were basically normal .Conclusion Lag screw could be used in condylar intracapsular sagittal fracture and the effect in recovery of the height of ramus and the function of joints is exact .关键词
