Use of a temporary screw for alignment and fixation of sagittal mandibular condylar fractures with lateral screws

Abstract 

This study introduced and evaluated the clinical application of a temporary and lateral screw technique for open reduction and internal rigid fixation of sagittal mandibular condylar fractures. A preauricular approach was used to expose the fracture. A temporary screw was used to assist in the anatomical reduction, and a lateral lag screw in combination with a lateral position screw was used for internal rigid fixation. Six adult patients with sagittal condylar fractures and more than 5mm condylar height shortening were treated. The treatment outcomes were followed up clinically and radiographically for 8–27 months (mean 18 months) postoperatively. There were no complications associated with the operation. All patients recovered favorably with good occlusion, normal movement of the mandible, correct repositioning and rigid fixation of the fragment of the fracture and a good condyle shape on radiographs. The temporary and lateral screw technique is a simple, effective, fast, and minimally invasive surgical treatment for adult sagittal condylar fractures.
