What is maxillary distraction osteogenesis?

Distraction osteogenesis is a surgical technique for reconstruction of bony deformities. Increased amounts of both bone and soft tissue are created as a result of the gradual displacement of surgically created bony fractures.

Does maxillary have advancement?

Internal DO is a successful alternative technique for maxillary advancement in cleft lip and palate patients that require an advancement under 10 mm. It causes improvements in the skeleton profile and in the soft tissue, increases the nasolabial angle and the inferior facial height.

What is maxillary hypoplasia?

Maxillary hypoplasia creates the illusion of a large chin due to a small upper jaw. This results in an underbite, which affects chewing, breathing, speech and long-term oral health. New advances like virtual 3-D surgical planning and “osteodistraction” are improving results for children needing facial reconstruction.

What is a bone distractor?

Distraction osteogenesis is a way to make a longer bone out of a shorter one. After a bone is cut during surgery, a device called a distractor pulls the 2 pieces of bone apart slowly. The slow stretching apart of bone is not painful. Children say it hurts less than braces they wear to straighten teeth.

How much does distraction osteogenesis 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.

What is a LeFort procedure?

The Le Fort Osteotomy is a type of jaw surgery used to correct an abnormally positioned jaw that gives rise to malocclusion problems (misalignment of teeth and jaws).

How far can you advance the maxilla?

Although somewhat variable in the literature, the maximum recommended advancement in cleft patients is around 6 mm. Combining maxillary advancement with mandibular setback has been a treatment option used for severe maxillary hypoplasia.

What is a maxilla?

The maxilla is the bone that forms your upper jaw. The right and left halves of the maxilla are irregularly shaped bones that fuse together in the middle of the skull, below the nose, in an area known as the intermaxillary suture. The maxilla is a major bone of the face.

How do you fix maxillary hypoplasia?

Treatment. Corrective surgery is the most common treatment used to correct maxillary hypoplasia. It involves repositioning the upper jaw in order to align it with the lower jaw and provide the face with overall symmetry.

Is maxillary hypoplasia genetic?

Maxillary hypoplasia in cleft individuals is partly due to the intrinsic deformity, partly due to genetic inheritance of facial growth pattern, and partly the result of scar from the multiple surgical interventions.

Is height increasing surgery worth it?

Surgery to get taller can help correct differences in leg length that could lead to adverse side effects, and can also address cosmetic concerns. Surgical innovations mean a person may not have to wear an external fixator or fixators as they once did.

How long does distraction osteogenesis take?

Distraction osteogenesis is performed as an outpatient surgery in our accredited surgical facility. Patients undergoing this procedure will require general anesthesia. The procedure takes anywhere between 2-3 hours.

When to use distraction osteogenesis for maxillary expansion?

Distraction Osteogenesis for Maxillary Expansion (DOME) Therapy Distraction Osteogenesis for Maxillary Expansion, which is also referred to as DOME was created at Stanford University. Dome is used to expand the upper jaw in adults. In the past, maxillary expansion procedures have had unpredictable results.

When to use the maxillary distractor in surgery?

The Maxillary Distractor is indicated for use in cranio- facial surgery, reconstructive procedures, and selective orthognathic surgery of the maxilla. Specifically, it is intended for distraction of the maxilla utilizing a LeFort I osteotomy in adult and pediatric populations. Contraindication

When to use distraction osteogenesis for hypoplasia?

It was originally pioneered for limb lengthening but now has been adapted to many craniofacial techniques. Distraction osteogenesis has become the standard of care when treating severe mandibular hypoplasia leading to obstructive sleep apnea.

How is the dome used in maxillary expansion?

Dome is used to expand the upper jaw in adults. In the past, maxillary expansion procedures have had unpredictable results. DOME, however, has consistently demonstrated positive results in improving nasal breathing and providing space for the tongue. These are both important factors for improving the breathing while sleeping.
