Osteotomy- Bone cut and distractor device

Osteotomy- Bone cut and distractor device

The period during which the distractor device is turned at a rate of 1 mm per day till the desired length is reached. The cut bone segments move apart.

Distraction period- distractor pushing the cut bone segments apart creating new bone in between

Distraction period- distractor pushing the cut bone segments apart creating new bone in between

Consolidation Period

Activation of the distractor is stopped and the bone formed in the gap is allowed to mature. The distractor device is removed at the end of this phase.

Distraction period- distractor pushing the cut bone segments apart creating new bone in between

Consolidation period- active distraction is stopped and bone is allowed to mature -comparison of CT scans before and after treatment

Remodelling Phase

Remodeling of bone occurs after the distractor device is removed

After distractor device is removed, successful completion of distraction to treat face asymmetry

After distractor device is removed, successful completion of distraction to treat face asymmetry
