Child mandibular distraction osteogenesis Jaw Lengthening (1334)

Key points below


Jaw lengthening

Your child’s lower jaw is too small or uneven. One or more surgeries will be needed to lengthen your child’s jaw. The process, called Mandibular Distraction Osteogenesis, will help make your child’s jaw larger. This process will take place over a period of time.

What is the process?Mandibular 2 images EN

  1. Surgery is done to cut the bone of the jaw.
  2. A distractor device will be placed either outside (external) or inside (internal).
    • External device. Pins are put in the jaw on each side of the cut. The device is attached to the pins.
    • Internal device. 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. This is called the latency period.
  4. The device is turned (activated) each day to allow room for new bone to grow. This is called the activation phase. Your surgeon will teach you how to turn the device at home.
  5. Your child will be monitored weekly by the surgeon in clinic during this process.
  6. 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 becomes solid. This is called the consolidation phase.
  7. Once the bone is solid (about 6-10 weeks later), the device is removed in the operating room.

What happens after surgery to place the distractors?

Diet:

Your child will be asked to gently use the muscles of the jaw often. To do this they will be asked to talk and chew.

Pin Care:

  1. You will need to clean the pin sites at home. Your child’s health care provider will tell you how often to clean the pin sites at home.
  2. Mix equal amounts of one-half (1/2) 3% Hydrogen Peroxide and 1/2 tap water.
  3. Dip a cotton swab in the solution and gently moisten the skin around the pin.
  4. Clean off any crusty material or drainage.
  5. Dip tap water on a new cotton swab and moisten the area again.
  6. Dry the area with another cotton swab.
  7. Use a new cotton swab to put a very fine layer of double antibiotic ointment on the skin at the base of the pin.


Your child’s health care provider will tell you how often to do the pin site care.
