1. Extraoral incision: make a 3-5 cm incision in the mandibular angle and remove the mandibular angle. Advantages: the operation is performed under direct vision, which is safer; The masticatory muscles can be cut off at the same time without complicated equipment and instruments.
2. Postauricular incision: Make a 3-4 cm incision behind the ear to remove the mandibular angle. Advantages: the incision is relatively hidden and the operation is relatively simple.
3. Combined incision inside and outside the mouth: A 3 cm ~ 4 cm incision is made in the mouth and two 0.5 cm ~ 0.8 cm incisions are made under the mandible, which can easily remove the hypertrophic mandibular angle, and at the same time, the mandibular outer plate and mandibular margin can be removed, and part of the masseter muscle can be removed. Advantages: The operation is very convenient, and many beginners use this method. After a period of recovery, the micro-incision under the mandible is not obvious.
4. Submandibular micro-incision: it is to use the combined incision inside and outside the mouth to insert a 0.5 cm ~ 0.8 cm micro-incision of the chainsaw to complete the whole operation process. The incision is under the mandible, and it is not obvious after 3 ~ 6 months. Advantages: this method has no incision in the oral cavity, less surgical trauma and rapid postoperative recovery.
5, complete intraoral incision: it is the best surgical method at present. It is to use a 3 cm ~ 4 cm incision in the oral cavity to cut off the hypertrophic mandibular angle, and at the same time, it can cut off or grind off the mandibular outer plate and mandibular margin, and can cut off part of the masseter muscle.
These are some methods of mandibular angle osteotomy and plastic surgery, hoping to help more beauty lovers change their success.
