What is the difference between mandibular angle osteotomy and mandibular angle grinding?

The differences between mandibular angle ostectomy and mandibular angle grinding lie in the surgical techniques and safety levels. Ostectomy involves using surgical instruments to cut the prominent mandibular angle and outer cortical bone into two symmetrical halves, achieving left-right symmetry. Mandibular angle grinding carries higher surgical risks, causes soft tissue damage, makes it difficult to control the amount of bone removed, and often results in asymmetry after surgery. Ostectomy is more complex and riskier than grinding, requiring a higher level of technical skill from the surgeon.
