[Reduction and screw fixation of condyle sagittal fracture].

OBJECTIVE

To investigate the technique and clinical effect in the surgical reduction and screw fixation of sagittal condylar fractures.

METHODS

Open treatment was performed on 21 cases (23 condyles) with sagittal condylar fractures. The condylar fracture segment was reduced and fixed by screw (long screw or lag screw). The patients began the mandible movement exercise early after the operation, and follow-up was performed in the first half year after the operation.

RESULTS

Favorable results were obtained in all cases. Slight malocclusion was observed in 3 cases accompanied with mandible fracture, but normal occlusion was almost reestablished after one week of intermaxillary traction. The CT examination indicated the ideal condition of reduction and fixation of these condylar fractures. During the follow-up, the mouth opening was normal, and mandible movement and function was satisfactory.

CONCLUSIONS

The technique of reduction and screw fixation in condyle sagittal fracture can obtain stable reduction and fixation.
