Firstly, it will lead to slow growth because children with snoring have reduced sleep quality and reduced release of growth hormone, which affects the growth and development of children. Secondly, it will lead to the child’s backward intellectual development; because these children are seriously deprived of oxygen during sleep, which directly leads to the lack of oxygen supply for brain development and will affect the child’s intellectual level. Once again, the long-term open-mouth breathing of children affects the face of children. When children snore, due to nasopharyngeal obstruction and open-mouth breathing, the upper and lower teeth bite together abnormally, and over time, the upper teeth may appear to be convex, the lips are upturned, the face is elongated, and the eyes are dull, which is called “adenoid face”. Adenoid hyperplasia can also cause exudative otitis media, and if it blocks the pharyngeal orifice of the nasopharynx, it can lead to recurrent exudative otitis media, with symptoms such as stuffy ears, tinnitus, and hearing loss.
