Adenoid hyperplasia has the potential to heal on its own. Adenoids can become noticeably enlarged by the age of 3-4 years, especially after a cold. However, by about 9-10 years of age, the adenoids may shrink on their own and usually do not require treatment. If a child’s adenoids do not atrophy, active intervention is needed because long-term adenoid hyperplasia can affect the facial growth and development of children with adenoids, causing facial deformities such as widened interbrow spacing, widened nasal bridge, enlarged nostrils, high arched palate, receding lower jaw, and overdeveloped upper jaw. At the same time, enlarged adenoids can block the posterior nostril and nasopharynx, causing poor nasal ventilation and leading to hypoxia in children, which has a greater impact on the brain and heart. Clinical treatment for adenoid hyperplasia includes nasal abnormalities and nasal spray of mometasone furoate. If conservative treatment does not work well, surgical removal of the hyperplastic, enlarged adenoids can also be considered.
