2. Patients must pay more attention to rest after operation, and strenuous activities can only be carried out in a few weeks after operation, so as to ensure the recovery of the surgical site as soon as possible.

3. Cosmetics can be used two weeks after operation, but be careful not to use force. It is generally not recommended to lose weight about one year after operation, because it will affect the surgical effect to some extent.

4. If the subject has a hobby of smoking or drinking, it is best to quit smoking and drinking within one month after operation.

5. Prevent infection after operation, use antibiotics and keep your mouth clean. Subjects must pay attention to keep a light diet and avoid seafood, spicy food and irritating food.
