The Chinese character face caused by living and eating habits is partly caused by the hypertrophy and brawniness of the mandibular angle on one side of the mandible. Mandibular angle can be corrected by plastic surgery.
There are two methods for plastic repair of mandibular angle hypertrophy in clinic.
1. Hypertrophic mandibular angle plasty; The ascending ramus of mandibular margin is too long, resulting in an angle less than 120, which is seriously at right angles. By cutting off too many "angles", the angle can be returned to 120, and the curve is smooth. The operation time is short.
2. Hypertrophic mandibular angle plastic surgery; Mainly aimed at the hypertrophy of the mandible, the ramus ramus ascendens of mandibular angle (exoskeleton) is ground off to make the mandible look sharp and thin, with the effect of face-lifting and smooth face shape.
Suggested surgical plan for mandibular angle plastic surgery
If the appearance is affected by excessive hypertrophy, it is suggested to use hypertrophy mandibular angle plastic surgery to restore normal face shape.
For those with moderate hypertrophy who want to face-lift, it is recommended to use hypertrophy mandibular angle plastic face-lift surgery to truly achieve the effect of star melon seeds.
For those with slight hypertrophy and small skull, it is suggested to use the mandibular angle shaping grinding method, because it is not necessary to cut off too many bones, just trim the shape. Of course, we should consider the coordination of each person's five senses, not blindly pursuing face-lifting, but also considering the distance between the zygomatic arches.
Selection of surgical incision
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. 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.
Causes of mandibular angle hypertrophy
One is bone hypertrophy of mandibular angle.
Second, the masseter muscle is overdeveloped, with prominent cheeks on both sides. Specific to each patient, the influence of the two causes may be different, which may be skeletal or muscular, but from the clinical experience, they are often accompanied at the same time. Some patients are also caused by heredity, and their parents or relatives often have mandibular angle hypertrophy.
