Infant mandibular distraction osteogenesis Jaw Lengthening (1335)

Key points below


Jaw lengthening

Your infant’s jaw was not fully developed at birth. The tongue is attached to the jaw. When an infant’s jaw is small, the tongue (which is normal size) is farther back in the throat. This may cause the airway to be blocked. If there are breathing problems, your infant may have a hard time feeding and gaining weight.

One or more surgeries will be needed to lengthen your infant’s jaw. The process, called Mandibular Distraction Osteogenesis, will help make your infant’s jaw larger. This process will take place in the hospital over a period of time.

What is the process?Jaw extending device

  1. Surgery is done to cut the bone of the jaw.
  2. A distractor device will be placed in one of these ways.
    • Externally (outside). An external device is used. Pins are put in the jaw on each side of the cut. The device is attached to the pins.
    • Internally (inside). An internal device is used. This is put right on the bone on either side of the cut, and left under the skin.
  3. A period of time is allowed to pass to prepare the bone.
  4. This is called the latency phase.
  5. The device is turned (activated) each day to allow room for new bone to grow. This is called the activation phase.
  6. The activation phase takes place in the hospital.
  7. After the activation phase is complete, the device is left in place. It holds the bones in place until the newly formed bone matures and gets solid.
  8. This is called the consolidation phase.
  9. About 4 to 6 weeks later, the bone becomes solid. The device will then be removed in the operating room.
