The maxillary occlusion abnormality of the maxillary correction is greater than that of the upper and lower jaw. The main surgical methods are incision in the mouth, through the osteotomy and advancement of the retracted bone tissue, or osteotomy and retreat The protruding bone tissue is used to achieve the purpose of correcting the anti-jaw. Such methods may damage the alveolar curvature and remove the teeth that hinder osteotomy. The damage is large. It is a four-level project in the classification of the medical beauty project of the Ministry of Health. It should be performed in the plastic surgery of a tertiary plastic surgery hospital or a tertiary general hospital.

Therapeutic effect: permanent retention Suitable for the crowd: simple jaw retraction or jaw retraction and mandibular protrusion combined recovery time: 1-3 months

Indication

Simple maxillary retraction or maxillary retraction combined with mandibular protrusion.

Contraindications

1 People with heart disease, high blood pressure, diabetes or other important organ diseases.

2 Severe scars.

3 There are odontogenic or sputum-induced infections in the maxillofacial region.

4 pregnant or menstrual women.

5 People with psychological disabilities.

Preoperative preparation

1 Do not take aspirin-containing drugs within two weeks of surgery.

2 Physical health should be determined before surgery, no infectious diseases or other physical inflammation.

3 Do not apply makeup before surgery.

Treatment and process

1, using the method of intravenous compound anesthesia, in the mandibular surgery can be carried out completely without pain, do not worry about the pain.

2, the use of accurate minimally invasive internal incision in the mandibular plastic surgery, can completely avoid the problem of leaving scars on the external skin. For the removal of the excess mandible, both the inner and the outer are removed, and then the outer edge of the remaining mandibular angle is polished to make it thinner, and the problems of various severe mandibular angles are wide. It can be solved fundamentally, and the purpose of reducing the sides of the face can be easily achieved. At the same time, the mandibular angle surgery needs to remove the masseter muscle and fat pad according to the condition of the facial tissue. Under the premise of ensuring safety, the curvature of the face is required to form the face of the melon.

3, mandibular angle surgery is safe and rapid, less traumatic, rapid recovery, will not damage the nerves and blood vessels of the face, avoiding the complications of mandibular surgery.

treatment effect

The operation is to remove the bone tissue layer by layer, and then use the osteotomy instrument to cut the bone, and the maxilla is retracted as a whole to correct the maxillary retraction, thereby achieving the purpose of correcting the anti-mandibular deformity. For those who are too occluded in the occlusion relationship, orthodontic treatment should be done in the dentistry before surgery to rearrange the crowded and disordered teeth to prepare for the later surgery.

complication

1. Infection: Any operation may have infection, especially in the intraoral incision, eating and other reasons will increase the possibility of infection, postoperative antibiotics should be taken 5-7 days.

2, upper and lower jaw fractures: when using a bone cutter to knock the osteotome to remove harder bone tissue, excessive force is likely to cause fractures.

Rehabilitation and care

1 After chewing, you can chew, but you can't do squatting, biting, etc. within three months.

2 Keep the surgical site clean and hygienic, and try to avoid water in the surgery area within 7 days after surgery.

3 Avoid eating irritating foods such as peppers.

4 Strictly follow the doctor's medication and referral.

Risk and prevention

1, hemorrhage and postoperative hematoma: more bleeding during osteotomy, easy to form congestion.

2, nerve damage: in the process of layer by layer peeling may cause nerve damage.

3. Bilateral asymmetry: When the bone tissue is cut off, it may cause asymmetric removal of the bilateral bones.

4, the effect is not ideal: there may be too many bone tissue removed during surgery, causing other types of deformities, it is also possible to cut too little to achieve the desired effect.

Physiology and aesthetics

The upper and lower jaws are located in the lower middle third of the face, which constitutes the lower half of the face and is one of the most important aesthetic structures of the face. The composition of the upper and lower jaws participates to some extent in determining the contours of the front and side views of the facial shape. The appropriate coordination between the jaws will highlight the beauty and three-dimensionality of the facial movement, while exuding a different kind of appearance. Sexy beauty.
