  Adenoid
The adenoid is a lump of tissue at the back of the nose above the tonsils.
The adenoid is a part of a group of lymph nodes that include the tonsils, found around the back of the throat (known as Waldeyer's ring).
In most children, the adenoid enlarges normally during early childhood, when infections of the nose and throat are most common.

  Adenoid - Wikipedia, the free encyclopedia
Adenoids, or pharyngeal tonsils, are folds of lymphatic tissue covered by ciliated epithelium.
Adenoids are part of the immune system as they trap inhaled viruses and produce antibodies, particularly in children.
Enlarged adenoids can obstruct breathing through the nose, and it is common when this happens for them to be surgically removed in a procedure called adenoidectomy.

 Adenoid Enlargement/Adenoid Hypertrophy
Although the exact function of adenoids is not understood, it may be related to some sort of protection from infection, but people can live normally without them.
As a child grows, so do the adenoids, reaching their maximum size when the child is 10 to 12 years old.
The decision to remove the adenoids must come from weighing the benefits of waiting for the adenoids to shrink on their own against the degree of disruption to a child's life and health.

Adenoid cystic carcinomas in the head and neck have been treated most frequently with surgical resection.[3] The combination of surgery with preoperative or postoperative irradiation improves both local control of disease and disease-free survival.[31-33] The rarity of lymph node metastasis[35] suggests that radical node dissection probably is unnecessary.

Adenoids are lymphoid tissue located in the back of the nose.
Although the tissue composition of adenoids is the same as that of the tonsils, the diseases associated with infected adenoids differ from the diseases associated with infected tonsils, based on their location.
The 2 operations were routinely performed together beginning in the early part of the 1900s, when the tonsils and adenoids were considered reservoirs of infection that caused many different types of diseases.

Adenoids are high in the throat behind the nose and above the roof of the mouth (soft palate) and are not visible through the mouth without special instruments.
