Objective To evaluate the curative effect on treatment of mandible condylar neck fractures with the kirschner pin.Methods In this study,9 cases of fracture of the mandibular condyloid process in which there was osteosynthesis using the Kirschner pin were followed radiographically. Results The X ray findings of 9 patients showed near anatomical reconstruction with good functional results. The follow up period ranged from 6 to 36 months with a mean of 24 months. Bony union was obtained in all fractures with no permanent facial nerve injuries and good mandibular opening (average of 35 mm).Conclusion This technique can be an effective approach for the treatment of selected condylar fractures.
