Scarring occurs after tonsillectomy surgery and is noticeable in the area after the patient opens his or her mouth. If patients have difficulty opening their mouths for a short period of time or feel that their throats are particularly tight, this is often due to the scarring that remains after tonsillectomy. Patients can do more chewing with the mouth open, which can effectively improve the scarring. If the patient is keloid, it may be more obvious, so the patient must be psychologically prepared. In life, we must exercise more, enhance the resistance ability, avoid frequent inflammation of the tonsils, so as not to need to remove the tonsils. Patients can consider oral vitamin C tablets to improve their immune ability, must actively rinse the mouth after eating, usually avoid smoking, drinking alcohol, avoid staying up all night.
