1, mandibular angle plastic grinding is not in place, and the preoperative and postoperative contrast is limited.
2. The curves on both sides of mandibular angle plastic osteotomy are obviously asymmetrical, and the face is obviously tilted forward, which is medically required to be basically symmetrical, not necessarily 100% symmetrical.
3. Maxillary angle plastic surgery only removes the mandibular angle without removing the outer plate, which can not achieve the effect of face-lifting, although the side is effective. This dissatisfaction rate is the highest.
4. The overall appearance of mandibular angle plastic surgery is not ideal, and the proportion of cheekbone, zygomatic arch and mandibular angle is not harmonious.
5, mandibular angle plastic zygomatic bone truncation is not fixed and then moves down, leading to imbalance. Generally, it is more reliable to fix with titanium plate. Some doctors who take care of patients to reject foreign bodies are not fixed, but there is a risk of downward movement, but it is not 100%, but titanium plate fixation will not 100%.
6, mandibular angle plastic zygomatic arch has not been greatly improved, mostly superficial grinding, not truncated and pushed in, so the effect is limited.
7, mandibular angle plastic surgery, its own skull is greatly improved, face-lifting is limited, leading to dissatisfaction. There are also many guests, usually blind people, who are eager to become melon seeds.
8. Excessive plastic osteotomy of mandibular angle, resulting in "horse face" and missing angle.
9, mandibular angle shaping straight osteotomy, forming a double angle, because arc osteotomy requires a certain technology, it is difficult for beginners to operate remedial measures.
