After tonsil surgery, diet is more important. Children are reluctant to eat and speak due to pharyngeal pain, so it is important to encourage them to eat and speak as early as possible. If the child does not eat, the wound recovery will be affected, and if the child does not speak, scars will be formed, which can affect the function of the pharynx. Therefore, early eating and early speaking is the best guarantee for recovery, and when eating, we should pay attention to the slow transition from cold liquid to semi-fluid to normal diet, and it is better not to eat too hard things too early. In addition, pay attention to oral hygiene, rinse your mouth carefully after eating to prevent secondary infections from food residues.
