[Application and effective evaluation of rigid internal fixation with double plates in condylar fracture].

OBJECTIVE

This study aims to explore and evaluate internal fixation with double titanium plates in mandibular condylar fracture.

METHODS

Twenty-eight patients with mandibular condylar fracture were treated by rigid internal fixation with double titanium plates. The effects of the treatment on occlusion, mouth opening, and titanium plate rupture were evaluated by pantomograms or 3D CT.

RESULTS

Good retention was observed in all 28 patients with mandibular condylar fracture. Occlusion and mouth opening returned to normal. None of the patients experienced titanium plate rupture or fracture displacement. Two patients suffered from mild facial nerve injury but recovered within 3 months after neurotrophic drug treatment. Two patients suffered from temporo-mandibular joint disease but improved after plate removal.

CONCLUSION

Rigid internal fixation with double titanium plates is an ideal treatment for mandibular condylar fracture.
