Various incisions are as follows:
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.
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.
Submandibular micro-incision: it is to use the combined incision inside and outside the mouth to insert the 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.
Combined incision inside and outside the mouth: it is very convenient to make a 3 cm ~ 4 cm incision in the mouth and two 0.5 cm ~ 0.8 cm incisions under the mandible to remove the hypertrophy of the mandibular angle. At the same time, the mandibular lateral plate and mandibular margin can be removed or ground, and part of the masseter muscle can also 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.
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. It is also because of the intraoral approach that the chance of damaging facial blood vessels and nerves is avoided. The technical requirements for operation are high.
The patient got careful care in the hospital and finally recovered, thanks to the hospital staff. The following is a thank-you letter I brought to your
