Mandibular angle osteotomy is currently a very ideal way to improve the shape of the face. It is necessary to use a 3 cm to 4 cm incision in the mouth to cut the hypertrophic mandibular angle in an arc, and at the same time, the outer plate of the mandible and the mandibular margin can be removed, and part of the masseter muscle can be removed.
Mandibular angle osteotomy is suitable for which beauty seekers
In line with the standard of the public aesthetic jaw angle, the general angle is about 120 degrees, and the distance from the jaw angle to the ear root is more appropriate, which can add a certain three-dimensional sense to the face, and the longer the distance from the ear root point to the jaw point, the more square the face will be.
Some beauty seekers are not sure if they should have surgery. In fact, there is no hard standard for jaw angle surgery, and the face shape of many beauty seekers may not be large as a whole, but because the angle of the jaw angle is too small or extended, the face shape is not beautiful.
In a nutshell, surgery can be considered as long as the angle of the jaw affects the harmony and aesthetics, resulting in a contour line that is not smooth enough. Beauty seekers can first make self-observation measurements and calculate whether the size of the jaw angle is in line with the normal state according to the above standards.
At the same time, you can also observe the contours of the face, if the face appears in a more obvious chinese font state, and even the width of the mandibular angle exceeds the width of the cheekbone, it is a problem that the mandibular angle is low and hypertrophied.
Why long-curve osteotomy is recommended
Compared with the traditional short curve osteotomy and bone grinding method, it is currently recommended to choose mandibular angle long curve osteotomy because it has the following advantages.
(1) Long curve mandibular angle shaping is carried out according to the aesthetic standards of human mandibular angle curvature, and the curvature of the mandibular angle is beautiful, which minimizes the risk of mandibular angle surgery and avoids the edges and corners caused by traditional mandibular angle surgery.
(2) Long curve mandibular angle plastic surgery can maximize the interception of hypertrophic mandibular angle, and can have a good modification effect on the asymmetry of the mandibular angle and the excessive width of the cheek.
(3) Long curve mandibular angle surgery takes a complete intraoral incision, and no surgical scars will be left after the operation. Due to the streamlined effect, no signs of surgery will be seen after surgery, and short necks will not occur. Compared to traditional mandibular angle surgery, the recovery after long curve mandibular angle surgery is faster, and no bone grinding is required after surgery to form a perfect linearity.
(4) The secondary split bone in the long curve mandibular angle surgery can narrow the width of the mandible, and this mandibular angle plastic surgery narrows the front view of the face, which can reduce the volume of the masticatory muscles and achieve a perfect facial shape.
Factors that affect the size of osteotomies
Although the same long curve osteotomy is performed, even if the appearance of the face is similar, the actual osteotomy will be different. The size and length of the bones cut by mandibular angle surgery are mainly related to the following factors.
(1) It is related to the method of surgery
Mandibular angle osteotomy surgery is divided into mandibular angle osteotomy, long curved mandibular angle osteotomy and mandibular angle chin combination surgery.
Mandibular angle osteotomy surgery is the traditional mandibular angle osteotomy, which is resected for the hypertrophic mandibular angle, the osteotomy line is relatively short, and the angle is squared but the mandibular morphology is better and does not require excessive excision.
The long curved jaw angle is a bone amputation method that starts from under the ear and goes all the way to a long curve near the chin position, the osteotomy line is long, the slope is gentle, the mandibular angle is smooth and the improvement effect is good.
(2) It is related to the lower alveolar nerve line
On the inside of the mandible, there is a lower alveolar nerve line that walks along the mandible. This nerve line cannot be cut, otherwise it will destroy the neurovasculars. If the angle of the lower jaw is cut too high or too much, it is possible to damage nerves and cause local numbness in the lips and chin.
Therefore, before the operation, it is usually necessary to take oral panoramas and skull CT films to determine the location of the neural tube and determine the specific range of osteotomy, not the more osteotomies everyone thinks, the better, and the safety of beauty is the most important.
Mandibular angle surgery is a fourth-level operation that requires a regular hospital with corresponding qualifications to perform, and it is recommended that beauty seekers seek medical treatment with caution.
