Purpose:After surgical interventions of mandible fractures, facial asymmetry can be occurred, and it leads to serious problems for patients. This can be solved by mandible angle ostectomy.
Methods:A 19-year-old male underwent percutaneous surgical intervention for left mandibular angle and right
parasymphyseal fractures 3.5 years ago. The left angle was protruded compared to the other side. Using a percutaneous
approach, 4.5 × 1 cm sized piece of mandible angle was sawed off. For the right angle, intraoral approach was
performed for angle ostectomy, and the angle was sawed off by a size of 4 × 1 cm, using a pattern based on the piece
from the left side.
Results:After surgery, no complications such as subcondylar fractures, refractures, insufficient corrections, secondary angle formations, hematomas, and transient nerve palsies were seen, and symmetric correction of mandible angles were done.
Conclusion:In facial asymmetries due to mandibular fractures, mandible ostectomy could be a solution. Using
the bone section from the contralateral side, measurement of the amount of bone sawed off was possible, and via
percutaneous approach on the previously operated site with simultaneous scar revision, and intraoral approach for the
contralateral side, cosmetically satisfactory result was obtained.
