Lymphatic tissue at the back of the nose.
A lymphoid mass similar to the tonsils containing lymphocytes and located in the nasopharynx.
A mass of tissue at the back of the nose and throat that can restrict breathing if enlarged.
Two small masses of tissue in the throat above the tonsils, which act as filters in the lymphatic system, the network through which the body’s immune system operates. Situated near the back of the nose, adenoids shrink from about age five, normally disappearing by puberty; but in some children they enlarge so as to obstruct the air passages, which causes snoring, a “nasal” voice, and breathing through the mouth. Sometimes they also affect the eustachian tube, resulting in EAR and hearing problems. If a child has recurrent severe infections, the adenoids may be removed in an adenoidectomy, often at the same time as a tonsillectomy.
Lymphatic tissue in the back of the nasal passage, on the wall of the nasopharynx. Adenoids may become enlarged and cause difficulty in breathing through the nose after repeated infection. Also known as pharyngeal tonsils.
Lymphatic tissue on the back of the nasopharynx; also called pharyngeal tonsil.
One of two small masses of tissue at the back of the nose above the tonsils. Also known as pharyngeal tonsils, the adenoids are part of the lymphatic system, and their function is to stop disease-causing microorganisms from entering the body through the nose or mouth. Adenoids tend to enlarge during childhood and are a frequent site of infections. But adenoids shrink in most children after age 5 and may disappear by puberty.
The collection of lymphatic tissue at the rear of the nose. Enlargement of the adenoids from recurrent throat infections may cause obstruction to breathing through the nose.
Lymphoid; having the appearance of a gland.
Lymphatic tissue forming a prominence on the wall of the pharyngeal recess of the nasopharynx.
A cluster of glandular tissue located at the rear of the nasal passage, situated above the tonsils, constitutes the adenoids. Comprised of lymph nodes, these adenoids play a crucial role in the body’s immune defense against infections affecting the upper respiratory tract. During early childhood, a period characterized by the prevalence of such infections, the adenoids have a tendency to enlarge.
In the majority of children, the adenoids undergo a reduction in size around the age of five, eventually disappearing entirely by the time they reach puberty. However, some children experience an enlargement of the adenoids, leading to the obstruction of the nasal passage to the throat. This can result in symptoms such as snoring, mouth breathing, and a distinct nasal quality to the voice. Additionally, the eustachian tubes, which connect the middle ear to the throat, may become blocked, leading to recurrent infections of the middle ear and potential hearing loss.
When the flow of secretions behind the nose is obstructed, it can give rise to rhinitis, an inflammation of the nasal passages. This inflammation has the potential to extend to the middle ear as well as the air sinuses located behind the nose.
As a child grows, the frequency of infections typically diminishes. However, if the infections persist and do not decrease over time, a medical professional may suggest adenoidectomy, which involves the surgical removal of the adenoids.
The term is commonly linked with adenoids or swollen glandular tissues located at the back of the nasal passage. This tissue is similar to tonsils, which are found at the back of the throat. Essentially, tonsils are the throat’s adenoids, and adenoids are the nasal cavity’s tonsils. Enlarged adenoids are frequent in children and can obstruct the nasal passage. This blockage can also affect the ear’s drainage tube, leading to recurring inflamed eardrums and, if left untreated, potential hearing loss. Signs of this nasal blockage in children include mouth breathing, frequent snoring, and in severe cases, a noticeable decline in mental alertness and a facial expression that could be described as fish-like. Removal of the adenoids often results in significant improvements, including changes in facial appearance, apparent cognitive sharpness, and the cessation of recurring earaches and nasal blockages.
