First, mandibular angle surgery is best done every morning; The difficulty, risk and technical requirements of mandibular angle surgery are relatively high, so the surgeon needs to concentrate on this operation. Moreover, the operation of mandibular angle takes longer than other operations, and the whole operation process takes 4 ~ 5 hours to complete. Long-term surgery is a great challenge for doctors, so they should concentrate all the time. Everyone is full of energy every morning, so it is best to perform this operation in the morning.

Second, the mandibular angle surgery is best to start at 10 every morning; There is a popular saying in the plastic surgery field in South Korea that it is best to start the operation in the morning 10 for difficult surgery, such as mandibular angle surgery, so that the success rate of the operation will be higher. This trend has been circulating for a long time and has not been retained so far. Koreans firmly believe that this practice is correct.

As for the unreliable problem, it is still quite reliable.
