1. Intra-oral incision method: The mandible can be modified by intra-oral incision, and some bones can be removed or a prosthesis can be placed in a certain part of the mandible, thus changing the shape of the mandible. It has the advantages of less surgical trauma and no trace on the face after operation. It is widely used in clinic at present.
2. Mandibular incision method: make an incision in the mandible and place the prosthesis in the front of the mandible through the mandibular incision. The surgical trauma is small, but a linear incision mark will be left on the mandible after operation. So now it's basically eliminated.
3. Full-thickness osteotomy of mandibular point curve
Methods: Since 2008, 565,438+03 patients with mandibular angle cosmetic surgery have undergone point curve full-thickness mandibular osteotomy with our own patented variable mandibular osteotomy device. Facial swelling was observed after operation, and the patients were followed up for 1-6 months. By comparing the anteroposterior and lateral photos of mandibular angle before and after operation, combined with clinical X-ray films, the morphology of mandibular angle was observed and compared with that after other operations in the same period.
Results: The point curve full-thickness osteotomy of mandible had nothing to do with soft tissue, which prevented the accidental injury of blood vessels and made the operation safe. Because the positioning osteotome is used to locate the whole hole, the osteotomy is accurate, the osteotomy line can be bent, the perfect second mandibular angle is retained after operation, and the mandible is symmetrical on both sides. Because there is no surgical field of vision needed for saw blade osteotomy, the peeling range is small, the soft tissue injury is small, the postoperative swelling is less, and the recovery is fast, which is deeply loved by beauty seekers. In other operations, mandibular angle osteotomy must have enough space. High-speed operation causes the saw blade and grinding head to slide, which may hurt the soft tissue and lead to tragedy. It is difficult to complete the full-thickness curve osteotomy with accurate positioning by relying on the linear motion of the saw blade and the plane grinding of the grinding head, and it is also impossible to retain the perfect postoperative second mandibular angle that conforms to the physiological function.
