Adenoids for child
The adenoids are situated at the back of the throat near the nasal passage. When they become enlarged they can cause mouth breathing, particularly at night, and snoring. This in turn may result in changes in the structure of the mouth so that the teeth become displaced. Orthodontic treatment may be required when the permanent teeth come through if mouth breathing persists. Adenoids are also a common cause of recurrent middle ear infections. If they become enlarged, they can block the bottom end of the Eustachian tubes which go up to the inside of the inner ears. The Eustachian tube allows air to enter the cavity behind the ear drum to equalise the pressure on both sides of the drum. Air pressure in the Eustachian tube vibrates when sound waves hit the ear drum so that any blockage of the Eustachian tube can result in deafness, infection, general lassitude and dullness. Removal of the adenoids if they remain enlarged is normally recommended. The operation is simple and requires a day or less in hospital. The child may speak with a nasal tone for many months after the operation but the pitch of the voice returns to normal in time.
Tonsils and adenoids. Allergic children frequently have enlarged tonsils and adenoids. Enlargement of the adenoids often results in middle ear infections and obstruction of the Eustachian tube (glue ear) which can cause partial or complete deafness. It is therefore important that the child with chronic hay fever be treated, or partial deafness could result. This in turn may mean that the child misses out on all-important language development, making for problems that are difficult to sort out later on. If the adenoids and tonsils of an allergic child are removed and the allergy is not treated and controlled, they may grow and enlarge again so that there is no long term benefit from the operation.
