Six hours after general anesthesia, water, milk, rice soup, fruit juice, chicken soup, fish soup and bone soup were given through nasal feeding tube. When the temperature is appropriate, after pulling out the nasal feeding tube, eat liquid foods, such as egg soup, gruel, wonton, noodle soup and other semi-liquid foods to avoid re-injury of the wound due to excessive mouth opening and eating hard objects.
