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.

Second, the incision behind the ear.

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.

Third, combined incision inside and outside the mouth.

It is very convenient to remove the hypertrophic mandibular angle by using a 3 cm ~ 4 cm incision in the oral cavity and two 0.5 cm ~ 0.8 cm incisions under the mandible. At the same time, the mandibular outer plate and mandibular margin can be removed or ground, and some masseter muscles 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.

Fourthly, submandibular micro-incision

It is to use the combined incision inside and outside the mouth to insert the 0.5 cm ~ 0.8 cm small incision of the chainsaw to complete the whole operation process. The incision is under the mandible, and the incision will not be obvious after 3 ~ 6 months.

Advantages: this method has no incision in the oral cavity, less surgical trauma and rapid postoperative recovery.

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.

Advantages: Because there is only one intraoral incision in the whole operation, no surgical scar will be left on the body surface, and the surgical trauma is much smaller than the combined incision inside and outside the mouth, and the recovery is obviously accelerated. Hedong pickaxe, the authority of maxillofacial plastic surgery in Korea, also adopted a minimally invasive method because of its oral approach, avoiding the chance of damaging facial blood vessels and nerves. The technical requirements for operation are high.

These are what I saw in Xiamen Huamei official website before. You can also collect Xiamen Huamei directly from Baidu. I hope my answer is helpful to you.
