What projects does Wei Minkepu want to improve the mandibular angle?
Mandibular angle affects the appearance of face, and if there is any problem, surgery is needed to improve it. In a variety of mandibular angle surgery, beauty seekers choose the appropriate scheme according to their own problems, which is more conducive to obtaining a natural and beautiful ideal face shape.

Problems existing in mandibular angle

Mandibular angle is an angular structure formed between mandibular body and mandibular branch. The masseter muscle has a stopping point at the mandibular angle. The contraction of the masseter muscle makes the mandible rise and the upper and lower teeth bite. Mandibular angle and masseter muscle stop at the back and lower part of human face, and their size and shape have an important influence on human face contour.

Generally speaking, Asians should pay attention to the following aspects in terms of aesthetic standards of mandibular angle.

1 angle. Harmonious mandibular angle, the angle between mandibular branch and mandibular margin should be about120.

2. Length. The ideal mandibular angle shape, the vertical distance from the earlobe to the mandibular angle position is about 2.5 cm, and the horizontal distance from the vertical line to the mandibular angle is about 1 cm. The longer the mandibular branch, the lower the mandibular margin, the higher the mandibular angle and the longer the length, so that the angle is closer to the 90 right angle and the face is more square.

3. width. The angle of mandibular angle determines the profile of the side, and the width of the outermost bone plate of mandibular angle determines the width of the front.

Simply put, the problem of mandibular angle is generally manifested as hypertrophy of mandibular angle. If the angle is too large, it will affect the appearance and require osteotomy. The other is the overgrowth of masseter muscle protruding from both cheeks. The cause of masseter muscle can be solved by facial acupuncture or surgical resection. It should be noted that if it is the mandibular angle, then the external application and injection of drugs will not achieve the effect.

Methods of improving mandibular angle

The mandibular angle and cortical bone in the outer layer of the mandible are mainly polished with a grinding head, and the mandibular angle is not removed. Sometimes, the mandibular angle is slightly polished or slightly raised with a suitable grinding head.

But the wear thickness is limited, only 5~6mm at most, and the improvement effect is not obvious. Moreover, because the bone grinding operation needs rotation, it is easy to involve soft tissue. Moreover, there are a lot of worn bone chips, and if they are not cleaned up, they will stick to the bones to form hyperosteogeny, which has certain risks.

2. Bone cutting method

Doctors need to design the shape according to the specific situation of beauty seekers before operation and remove part of the mandibular angle. Specifically, it can be roughly divided into two directions.

Short curve osteotomy. Short curve osteotomy refers to cutting off the angle of mandibular protrusion expansion. However, when the position of mandibular posterior ramus osteotomy remains unchanged, the cross-sectional angle of short curve osteotomy is small, so the probability of fracture is relatively higher than that of long curve osteotomy.

Moreover, the lack of transition buffer, simple angle cutting, not only can not improve obviously, but also easily form a new "submandibular angle", which leads to irregular mandibular line of postoperative beauty seekers.

Long arc osteotomy of mandibular angle. The mandibular angle was removed by arc saw osteotomy, which widened the distance between the cutting line and the nerve of mandibular angle sulcus and greatly improved the side view. In order to create a beautiful mandibular arc, it is sometimes necessary to remove part of the bones at the outer edge of the mandible, and it needs to be coordinated with the mandibular arc.

Long curve osteotomy is an ideal and commonly used method at present, which can effectively avoid the occurrence of secondary edges and corners after operation. However, osteotomy requires doctors' professional technical level and rich experience.

3. Outer plate segmentation

Generally speaking, in mandibular angle surgery, the bone plate on the outer side of mandibular angle is removed and the outer plate is split, which makes the frontal effect of mandibular angle surgery better.

Some beauty seekers' faces look from the front, the width of the lower half of the face is too wide, but the mandibular lines on the side are smoother. This kind of beauty seeker is suitable for thinning the outer plate area during mandibular resection to achieve the effect of face-lifting.

Mandibular angle surgery can effectively improve the problem of large face and wide face caused by wide bone, correct protruding parts and make facial lines more beautiful. The methods mentioned above are usually combined according to the specific situation of beauty seekers in mandibular angle surgery.
