What is mandibular distraction?
Jaw distraction is the name for a surgical method of lengthening a small or recessed (hollow or indented) jaw. The medical term for jaw distraction is mandibular distraction osteogenesis (man-dib-u-lar dis-track-shon osti-oh-jen-esis). A small or recessed jaw can cause severe or ongoing breathing difficulties.
What is mandibular distraction osteogenesis?
Mandibular Distraction Osteogenesis (MDO) is a surgery done for infants with Pierre Robin sequence. MDO lengthens the jaw to help open the airway so the baby can breathe safely and comfortably on their own.
Does the rate of distraction or type of distractor affect the outcome of mandibular distraction in children with Micrognathia?
Conclusions: In children younger than 12 months, distraction at a rate of 2 mm/d is safe and appears to have a similar success rate to distraction at 1 mm/d. Internal distractors have a higher success rate than external distractors and should be used when possible.
What’s the jaw bone called?
mandible
It consists of two main parts. The upper part is the maxilla. It doesn’t move. The moveable lower part is called the mandible.
Is osteogenesis distraction safe?
Mandibular distraction osteogenesis (MDO) is a relatively new treatment option in children with PRS, which has been shown to be very effective in relieving the upper airway obstruction by gradually lengthening the mandible. Overall, MDO is considered to be safe with low incidence of major complications [9, 10].
How much does jaw distraction surgery cost?
The cost for distraction osteogenesis will vary. In some cases, it will be combined with another jaw procedure. The technique itself starts at around $6,000 and increases (up to $12,000) depending on the severity of the condition being treated. In some cases, insurance may cover a portion of the procedure.
Is Pierre Robin inherited?
Isolated Pierre Robin sequence is usually not inherited. It typically results from new (de novo) genetic changes and occurs in people with no history of the disorder in their family.
What is the lower part of your jaw called?
The moveable lower part is called the mandible. You move it when you talk or chew. The two halves of the mandible meet at your chin. The joint where the mandible meets your skull is the temporomandibular joint.
When is distraction osteogenesis used?
Distraction osteogenesis is used to expand the facial skeleton in children with congenital micrognathia or midface hypoplasia. Distraction osteogenesis allows large advancements without the need for bone grafting and with less risk of relapse.
How is external mandibular distraction used in surgery?
External mandibular distraction involves making a mandibular osteotomy and applying an external device to slowly and gradually lengthen the mandible. This technique is used to lengthen the hypoplastic mandible seen in multiple craniofacial conditions.
How is external mandibular distraction used to treat micrognathia?
External mandibular distraction involves making a mandibular osteotomy and applying an external device to slowly and gradually lengthen the mandible. This technique is used to lengthen the hypoplastic mandible seen in multiple craniofacial conditions. The mandible is a unique U-shaped bone with two vertical rami and a horizontal body.
How is a distraction device attached to the jaw?
An incision is made and the jaw bone is carefully separated to allow a distraction device to be attached to the bone, on both sides of the jaw. The device has two screws that are turned to further separate the bone after surgery. These screws are turned approximately every eight hours for about 15 days.
When to perform Mandibular Distraction on a baby?
At CHOC, we specialize in performing mandibular distraction. We are one of a small number of hospitals to offer this unique procedure, with the goal of correcting the problem early in a baby’s life and avoiding more complex treatments and complications. Mandibular distraction is usually performed in the first several weeks of life.
