In clinical practice, different surgical methods will have different sequelae. Traditional adenoid curettage is prone to injury because the removal of glands cannot be operated under direct visualization, and it mainly relies on the surgeon’s experience and surgical proficiency, which may lead to nasopharyngeal hemorrhage, larger adenoids, and residual hyperplasia after the operation, and the residual adenoids are still susceptible to infections. Currently emerging surgical methods include plasma ablation of adenoids, which can be operated under direct vision and generally has fewer complications. However, if the operation is not done properly, it may cause sequelae, such as deeper operation, causing bleeding of blood vessels and nasopharyngeal muscles, postoperative mucous membrane adhesion leading to occlusion of the Eustachian tube, causing tinnitus and hearing loss, and so on.
