Adenoid enlargement surgery basically has no sequelae, which should refer to the surgical complications, mainly manifested as bleeding, ear stuffiness and postoperative recurrence. 1. Bleeding: Bleeding is mainly caused by factors such as incomplete surgical resection or damage to blood vessels. To avoid the sequelae of bleeding, it is necessary to avoid too deep resection during the operation. 2. Tightness of the ear: the adenoid is next to the cushion of the Eustachian tube, which is the opening of the Eustachian tube in the pharynx. Damage during surgery may lead to blockage of the Eustachian tube, which will be manifested as symptoms of tightness of the ear. 3. Postoperative recurrence: Adenoidectomy requires complete removal of the adenoids. If the adenoids are not completely removed during surgery, the residual tissue, if repeatedly irritated by inflammation, may lead to recurrence of the adenoids. After surgery, patients can eat semi-liquid, such as thin rice, pureed vegetables, etc., and also pay attention to the food temperature should not be too high. Try to eat small meals and gargle after meals to promote wound healing. Patients with enlarged adenoids are advised to go to regular hospitals for treatment under the guidance of professional doctors.
