There are muscle starting and ending points under the zygomatic arch. Excessive separation during surgery can lead to sagging and relaxation of facial muscles. Therefore, cheekbone surgery should not require too many amputations. If the zygomatic arch is pushed inward too much, it will produce a "click" sound when opening and closing the mouth, which will lead to failure to close it in severe cases.

Therefore, it is recommended that you cooperate with the lifting operation after cheekbone surgery. Of course, even without surgery, people will show signs of sagging when they get old.
