Before and After Mandibular Osteotomy

Lower jaw (mandibular osteotomy). The lower jaw is divided and the front section is moved forward or backward and secured with plates and screws.

Lower jaw surgery, a mandibular osteotomy, can correct:

  • Receding lower jaw
  • Protruding lower jaw

The surgeon makes cuts behind the molars and lengthwise down the jawbone so the front of the jaw can move as one unit. The jaw can then be moved to its new position either forward or backward. Plates and screws hold the jawbone together as it heals.
