Since the air isn’t passing through the nose, it is therefore not being purified, and the child is then more prone to infections of the nose, sinuses, ear and lungs. All of the above can slow down a child’s growth. The child is pale, breathes through the open mouth (because of the nasal secretion) and looks sleepy. Pressure applied to the Eustachian tube (a small tube regulating pressure in the middle ear) can cause bacterial inflammations of the middle ear so the child also experiences certain hearing problems.
It is very important to consult an otorhinolaryngologist who will use the anamnesis, clinical manifestations and the child’s age to assess whether surgery is needed.
