What Is the Mandibular Symphysis?

The mandibular angle is located on the lower and outer side of the face. It is composed of the connection between the ascending mandible and the body of the mandible. The lateral side of the masticator is trochanter with masticatory muscles attached. The medial is pterygoid tuberosity with pterygoid attachment. The mandibular angles on the left and right sides, the cheekbones, and the palate on both sides form the basic contours of the face, and the basic features of the facial form with the tissues and other organs in the face are the important anatomical features of the facial features.

Mandibular angle hypertrophy

The mandibular angle is composed of the mandibular branch of the mandible and the mandible. It is symmetrical on the face (normally). Generally, if the angle is too large, it will affect the aesthetics and require plastic surgery. Mandibular angle surgery is one of the methods to change the face shape in plastic surgery, including

The shape, size, and position of the mandibular angle are extremely important for facial appearance. The abnormality of the mandible angle is based on this

There are two main causes of mandibular angle hypertrophy: "worker hypertrophy" theory and genetic factors.

According to the shape of the mandibular angle, the mandibular angle hypertrophy can be divided into the following three types: mandibular angle posterior type mandibular angle eversion type mandibular angle eversion type

For Orientals, the main cause of the mandibular angle bone hypertrophy is that the mandibular angle is too posterior, valgus or both, so the focus of treatment is mainly on the osteotomy of the mandibular angle. Surgery It is considered to be the first and most effective way to treat mandibular hypertrophy.

Long curve mandibular angle osteotomy is a perfect combination of the two commonly used mandibular angle plastic surgery methods, namely osteotomy and osteotomy. This method can remove hypertrophic mandible on the one hand, and repair the osteotomy by bone grinding at the same time. The edges and corners make the face lines softer and smoother. This new

1. Check the degree of mandibular angle hypertrophy before mandibular surgery, and communicate with the surgeon in detail to determine the amount of mandibular angle or mandibular margin amputation.

2. Within two weeks before mandibular plastic surgery, do not take medicines containing aspirin, because aspirin will reduce the function of platelet coagulation.

3. Patients with hypertension and diabetes should inform the doctor of the condition at the time of the initial diagnosis so that the doctor can confirm the plan of mandibular plastic surgery.

4. Make sure that your body is healthy before mandibular surgery, and there is no infectious disease or other body inflammation.

5. Don't make up before mandibular plastic surgery.

6, women should avoid menstruation, pregnancy and pregnancy.

7. Men should quit smoking one week in advance.

1. Mandibular angle osteotomy: It is developed by cutting the bones of the face with the widest part-the bones of the mandibular angle. The width of the face is narrowed when viewed from the front, so that the face becomes a thin "goose egg face" or "melon face" Methods.

2, chewing muscle hypertrophy injection thin face technology: due to various reasons, such as night molars, lateral chewing and other habits caused chewing muscle hypertrophy, the face was square. The treatment method is very simple, the main injection is a needle, the face will automatically lose weight in about two weeks.

3. Aspiration of excessive buccal fat: one is the cellulite in a specific part (medically called buccal fat pad); the other is the same subcutaneous fat accumulation as the belly. The cause was immediately known by an experienced doctor. Use a special suction needle to suck or pull out fat to achieve

We often find that there are many abnormal people with large cheeks around. This face shape, which is no longer the regular Chinese character face, is medically called: mandibular angle hypertrophy or square face deformity. The way to improve is to match the face with "

First, the price of mandibular angle hypertrophy and plastic surgery is related to facial structure

Because the specific situation of each beauty lover is different, some people's faces are too wide, and some people only need to make fine adjustments, so the price of mandibular hypertrophy and plastic surgery has a great relationship with the original structure of the face.

Second, the price of mandibular angle hyperplasia is related to the surgical method

The methods of mandibular angle hyperplasia can be divided into Chinese and Korean. Therefore, the pros and cons of surgical methods are different, and the ease of surgery is also different. Therefore, the price of mandibular angle hypertrophy and plastic surgery will also be affected.

Third, the price of mandibular angle hyperplasia is related to experts

Mandibular angle hyperplasty is not a minor operation, it requires authoritative experts to build it, but the accomplishments of each expert are different, and the price of mandibular angle hyperplasty and plastic surgery just reflects their value, so experts have different mandibular angle The price of hypertrophy and plastic surgery is also different.

4. The price of mandibular angle hyperplasia is related to the hospital

The positioning of each hospital is different, and the strength of the plastic surgery equipment and the expert team is different. This has a certain reflection on the price. Therefore, the price of different mandibular hypertrophy plastic surgery for the selected hospital is also affected.

Although the harm of mandibular angle hypertrophy to human function is not very obvious, it has a great impact on human facial image and psychological aspects. Orientals admire: "

Mandibular masseter muscle hypertrophy, through its routine clinical examination, X-ray jawbone panoramic cephalometric film, research and analysis of all data in the absence of tumors and trauma, the characteristics of this type of doctor Table now:

(1) When viewed from the front, the lower third of the face is obviously large and square.

(2) From the side, it can be seen that the bone mass of the mandible corner is enlarged and thick, such as osteomas, and the thickness of the soft tissue in this area is also significantly increased, but the soft tissue is soft on palpation.

(3) The angle of GoGn-SN is too small, which indicates that the inclination of the mandible plane is too small, and the height of the 1/3 below the face is overcorrected, which is mainly manifested by the dysplasia of the vertical height of the skeleton, which aggravates the square face deformity.

It is best to stay in the hospital for observation for about 3 days after the mandibular angle hypertrophy resection. During the period, it is best to squeeze and bandage the wound for about a week. This can effectively prevent postoperative discomfort and swelling. Not correct within three months after surgery

One: Mandibular angle hypertrophy is mainly manifested in the impact on facial image and psychology. The characteristics of seekers are:

(1) When viewed from the front, the lower third of the face is large and square, and it is often accompanied by dysplasia of the vertical height of the crotch. The height of the lower third is too short.

(2) From the side, it can be seen that the angle of the jaw angle is sharp, protruding backward and downward, and the bone mass is abnormally increased.

(3) The thickness of soft tissues in this area sometimes increases significantly, but the soft tissues on this part are soft, without lumps and tenderness. When the patient is urged to bite hard, he can touch the obvious hypertrophic masseter muscles.

The characteristic manifestations of X-ray head test films are:

The distance between the mandibular angles on both sides increased or even greater than the distance between the two condyles.

On the lateral X-ray film, the mandibular angle (Ar-Go-Me angle) becomes sharp, which is 120 ° in a normal person. The mandibular plane angle (MP-FH angle) and the mandibular plane-anterior skull base plane angle, which can reflect the degree of downward protrusion of the mandibular angle, are straight. The more prominent the downward protrusion, the smaller the angle. The angle of the ascending plane and the anterior inferior plane, which can reflect the degree of the mandibular angle protruding rearward, increases with the increasing degree of the mandibular angle protruding backward. The measurement and analysis of the side film can determine the degree of hypertrophy and protrusion of the mandibular angle downward and backward.

2: The degree of mandibular angle hypertrophy is affected by many factors, including the angle of mandibular angle, the angle of mandibular inversion, the thickness of the mandibular body and the masseter muscle hypertrophy, the fullness of the cheek, and the relative proportion of the width of the middle face . There is no uniform diagnostic standard for the diagnosis of mandibular angle hypertrophy, and its judgment is often affected by subjective factors of patients and physicians, as well as different geographical and cultural backgrounds. Some people have done statistics on mandibular angle X-ray lateral radiographs. The angle of 59% of Chinese mandibular angle is between 110 ° and 120 °, and the diagnosis is considered to be less than 110 °. Some people also believe that the normal mandibular angle width equal to or greater than the width of the sacrum can be diagnosed.

The three sets of aesthetic evaluation data proposed by Barlett and others have guiding significance for the diagnosis of mandibular angle hypertrophy:

The distance from the lower nose point (sn) to the crotch (gn) on the side photo should be 1/3 of the entire face length;

The widest transverse diameter of the face in the orthophoto is the distance between the zygomatic arches on both sides, and the distance between the temporal sides of the two sides should be equal to the distance between the two mandibular angles and should be 10% smaller than the distance between the zygomatic arches. ;

(3) The angle of the mandibular angle is generally 105 ° to 115 °. In 1981, Farkes put forward a lot of related aesthetic clinical data through the measurement of Western facial features. It also pointed out that the angle of the double mandible should be 10% shorter than that of the double condyle when viewed from the front. But because of the wide cheekbones of Oriental women, sometimes square faces are still very obvious, although they meet Farkes' measurement standards.

3: The human face emphasizes harmony and unity. The diagnosis of mandibular angle hypertrophy is the result of a comprehensive consideration. When considering the diagnosis of mandibular angle, especially the treatment, it is necessary to comprehensively consider the angle of mandibular angle, the distance between the jaws, and the relationship of facial proportion. Comprehensive judgment can only be made when considering the overall coordination of the facial contour. In addition, in order to avoid misdiagnosis, it needs to be distinguished from some diseases, such as parotid gland disease, buccal fat pad hypertrophy, tumors, inflammation of the lower cheek, and ossifying myositis.
