Q

Mandibular Osteotomy

A

“Spreaders”. Changes the length of the mandible (usually done to shorten mandible for kids with cleft palate)
A cut is made through the gum behind the back teeth to gain access to the jawbone. The lower jaw is then cut with a small saw to allow it to be broken in a controlled manner. It is then moved into its new position and held in place with small metal plates and screws.
After the procedure, the process/goal is distraction osteogenesis. This is when two segments of a bone slowly apart in such a way that new bone fills in the gap.
