After the tonsillectomy, a white pseudomembrane will gradually form on both sides of the tonsil surgical wound, and this pseudomembrane usually takes about 2-3 weeks to gradually fall off. The white pseudomembrane formed after surgery will have a certain protective effect on the tonsil wound. During the existence of the pseudomembrane, patients need to pay attention to avoid an excessively coarse diet and gradually transition from a liquid diet to a semi-liquid diet and then to a soft diet, and they also need to pay attention to a proper light diet and not to eat spicy, stimulating and fire-prone foods. If the patient’s pseudomembrane is damaged, it may increase the risk of bleeding after surgery, and only after the pseudomembrane has completely fallen off on its own can the surgical wound heal completely.
