Adenoid hypertrophy is not a congenital disease, although there is a certain relationship with genetic factors, but most of them belong to the influence of acquired factors. For example, children’s body resistance is particularly poor, usually always cold, fever, runny nose, such conditions are particularly likely to lead to adenoid hypertrophy. In addition, some children have allergic rhinitis, which can also easily stimulate the adenoids to become enlarged. It is recommended that parents take their children to the hospital for a detailed examination to improve the lateral nasopharyngeal film or nasopharyngoscopy to clarify the specific degree of adenoid hypertrophy. If it is relatively small, it can be treated by spraying with Nesuna and Oronema drops. If the blockage is particularly pronounced, it is often necessary to solve it through surgery.
