In short, it is to polish off a part of the bones in the cheek and turn the dissatisfied face into a standard oval face or oval face.
Surgical location: some enter through the mouth, and some enter through the preauricular incision.
In many plastic surgery, compared with simple operations such as double eyelid surgery's (double eyelid), bone grinding is a major operation with a relatively high risk factor.
Facial bone grinding/osteotomy mainly includes:
Mandibular reduction sculpture
Mandibular angle plastic surgery is the most common face-changing surgery at present. The normal angle of mandibular angle is 120, which looks not sharp. Hypertrophy of mandibular angle includes two aspects: First, the angle of mandibular angle is too small, showing the face of "China people". Second, the valgus and thickening of the mandible make the face trapezoidal, which does not meet the aesthetic standards.
At present, with the improvement of surgical technology, effect and safety, not only the mandibular angle is obviously increased, but also the face is square, which seriously affects the appearance, and more women with slightly increased mandibular angle actively accept plastic surgery and become "Korean-style" little-faced beauty.
The operation of mandibular angle hypertrophy can be divided into extraoral approach, intraoral approach and combined approach, but the extraoral approach has been eliminated because of obvious scar. Bone removal methods can be divided into mandibular angle arc osteotomy, external plate splitting and mandibular angle grinding. Splitting the outer plate has a good effect on reducing the face shape, but it has an average effect on improving the mandibular angle. Mandibular angle grinding with outer plate can improve mandibular angle, with little damage and high safety. Arc osteotomy of mandibular angle has a good effect on improving mandibular angle and reducing face, and it is the mainstream surgical method to change face in the world at present.
Mandibular angle osteotomy reached the vestibular sulcus of mandibular second molar along the anterior line of mandibular ramus in the oral cavity, with a length of 6-8 cm, reaching the periosteum. The masseter muscle and medial periosteum were completely separated from the lateral plate of mandibular ramus, and then the medial muscle of mandibular angle wing was stripped with periosteum stripper. Linderf distractor is placed at the rear edge and corner of mandibular ramus, which fully exposes the mandibular angle and can be used for sawing or swinging saw to cut off the required bone pieces. Osteotomy types are divided into vertical sagittal osteotomy, oblique osteotomy, inverted L-shaped osteotomy and T-shaped osteotomy.
High zygomatic plastic surgery: zygomatic reduction sculpture
Westerners regard high cheekbones as beauty, and many western beauties have obvious high cheekbones and facial features. Oriental cheekbones are also very high, but in oriental culture, too high cheekbones form a triangular face, and the middle face is too wide and convex, giving people a cold feeling and looking haggard and aging.
Plastic and cosmetic surgery adopts special instruments for grinding bones imported from the United States, equipped with automatic protection device and cold light source system, so that bones can be ground in a small incision of 3cm in the mouth. Because of clear vision, good bone exposure and less bleeding, it can be carefully shaped without damaging facial nerve and facial artery. At the same time, because the redundant bones have been ground, the ground surface is very smooth, the face is natural after operation, and there is no trace outside the mouth. Professional doctors with rich clinical experience use high technology, combine your five senses and combine modern aesthetic principles to create. It is no longer a dream to have exactly the same person.
Special tips
The person undergoing the operation should be in good health and have no organic diseases of important organs, such as heart disease, hepatitis, nephritis, pneumonia and other diseases. No source of oral infection: such as dental caries, periodontitis, oral ulcer, etc. Female surgery should avoid menstrual period. Smoking should be stopped before the operation. Aspirin, birth control pills and some anti-inflammatory drugs can cause increased bleeding, so they should be stopped for a period of time before operation.
Special reminder
Bone grinding and face-lifting surgery is a very strict and meticulous operation, which usually requires very strict qualifications of surgeons, and the whole process of bone grinding surgery also has strict operating procedures.
Before the operation, the lateral X-ray film of the skull should be taken for the patient. On this X-ray film, the skull, jaw structure, tooth-jaw relationship and facial soft tissue should be measured, and the contours of the skull, jaw, teeth and facial soft tissue should be described with cellophane.
Through paper cutting and spelling, we can predict the bone parts, moving distance and direction that need to be moved during the operation, and predict the changes after the operation.
Sometimes it is necessary to take the membrane out of the patient's mouth to make a plaster model of the jaw teeth, and perform simulated surgery on this model. The operation should be performed under general anesthesia. Generally speaking, anesthesia is performed by tracheal intubation. The trachea is completely blocked because of the anesthesia pipe. In this state, it is difficult to inject blood into the trachea. In view of intraoperative bleeding, it is necessary to use an aspirator to suck in time and stop bleeding completely. As long as the operation is standardized, blood can be completely prevented from entering the trachea through the throat, leading to suffocation and death.
