1, mandibular angle grinding and plastic surgery
This operation is to remove the cortical bone of mandibular angle and mandibular outer layer by grinding head, and the mandibular angle is not removed. Sometimes the mandibular angle can be removed or slightly raised with a suitable grinding head.
Advantages: simple and safe operation, less bleeding.
Advantages: the original mandibular radian is retained, which is suitable for people who want to reduce the mandibular width but want to retain the mandibular angle.
2. Long curve mandibular angle shaping
In this operation, an arc saw osteotomy was used to cut the mandibular angle, which widened the distance between the cutting line and the mandibular sulcus nerve and greatly improved the side view. Moreover, the masseter lost the attachment of the mandibular angle and slowly shrank, which also solved the problem of masseter hypertrophy.
