Secretory otitis media is most common in children, with a higher incidence at younger ages. It is mainly triggered by prolonged colds, sinusitis, allergic rhinitis, etc. If secretory otitis media is not treated promptly and the fluid in the ear is not absorbed, it can lead to secondary diseases such as adhesive otitis media, tympanosclerosis, and cholesterol granuloma, resulting in permanent hearing loss. Treatment is very difficult. Infancy is a good time to learn language, and if language learning is impaired due to hearing difficulties, it is like closing a window for the child to know and perceive the world, which seriously affects the child’s mental development.
