Purpose : The aim of this study was to evaluate use of long screw in treatment of condylar process fractures.Methods: Sixteen patients underwent surgery for mandibular condylar fractures via a preauricular approach. The repositioned fragments were fixed using long screws . Clinical and radiologic examinations were recorded postoperatively. Clinical factors recorded were maximal mouth opening(MMO),diviation during opening, protrusion and laterotrusion, findings on palpation of the temporomandibular joints, nerve damage and other complications. Ramus height and angulation between the mandibular ramus and the fragments were measured and compared with the contralateral side preoperatively and the last follow up.Results: The postoperative course was uneventful in most patients. The average shortening of ramus height preoperation was 7 mm, and that of immediate postoperation was less 2 mm. There was significant difference. The average angulation in the anteroposterior direction preoperation was 34 degree, and that of postoperation was 10 degree. There was significant difference. The average angulation in the mediolateral direction preoperation was 55 degree, and that of postoperation was 16 degree. There was also significant difference . Seven patients were followed up (mean 9 months, range, 4-13 months), All patients were satisfied with their operations, the average MMO was 39 mm , there were no signs of deviation and TMD and other complications. All ramus height and angulation were normal except of one bilateral condylar fracture with moderate resorption.Conclusions: Treatment of mandibular condylar fractures using long screw is ideal in oblique condylar fracture, especial fracture related to intracapusule. The effect need further follow up . |
