Can mandibular angle plastic surgery make the face smaller? We first need to understand the concept of mandibular angle. The mandible is divided into a body and an ascending ramus. The two bodies unite in the middle. There are two bony protrusions above the ramus of the mandible. The one at the rear is called the condyle, and the one in front is called the coracoid process (muscle process). The concave edge between the two is called the sigmoid notch. The intersection of the posterior edge of the ramus and the lower edge of the mandible is called the mandibular angle. There is a hole in the middle of the medial surface of the ramus called the mandibular foramen. This hole is a tube extending downward and forward in the mandible, called the mandible.

When performing mandibular angle plastic surgery, attention should be paid to avoiding the facial nerves, analyzing the relationship between the local area and the overall facial beauty, considering the overall effect of the teeth, jaws, face, and skull, and ensuring the shape and function of the jaw bone. Mandibular angle plastic surgery mainly targets the obvious hypertrophy and valgus of the mandible, "Chinese face" or "trapezoid face". The mandible is prominent and asymmetrical on both sides. Those who have an uncoordinated facial width ratio and a wide distance between the two mandibles are more suitable for mandibular angle plastic surgery. There are two commonly used methods for mandibular angle plastic surgery:

1. Artificial mandibular implant for mandibular angle plastic surgery: It is suitable for people with retrognathia or small mandibles, and is also the most common surgical method. Most patients' jaws are a bit short but not too short. An artificial jaw is more natural, leads to higher satisfaction and fewer future complications.

2. Mandibular angle plastic surgery: Mandibular plastic surgery: suitable for those whose mandible is too short, too retracted, or whose mandible is skewed. If the patient's mandible has a short mandibular bone that is biased to the right, causing the face and mouth to become lopsided and the cheeks to be asymmetrical, appropriate proportion adjustments can be made. The method is to move the mandibular bone to the midline, lengthen it, and then stabilize the bone. This method can also be used if the mandible is too protruding.
