Pharyngeal tonsil Location of the adenoid Latin tonsilla pharyngea MeSH Adenoids
They also differ from the other tonsil types by lacking crypts. The adenoids are often removed along with the tonsils. This can cause a very sore throat for about a week and rather unpleasant breath. Most people's adenoids are not even in use after a person's third year, but if they cause problems they must be taken out or they may otherwise shrink.
Enlarged adenoids, or adenoid hypertrophy, can become nearly the size of a ping pong ball and completely block airflow through the nasal passages.
Even if enlarged adenoids are not substantial enough to physically block the back of the nose, they can obstruct airflow enough so that breathing through the nose requires an uncomfortable amount of work, and inhalation occurs instead through an open mouth.
Adenoids can also obstruct the nasal airway enough to affect the voice without actually stopping nasal airflow altogether.
Enlargement of adenoids, especially in children, causes an atypical appearance of the face, often referred to as adenoid facies.
Features of Adenoid facies include Open mouth/mouth breathing, Long elongated face, prominent incisors, Hypoplastic maxilla Short upper lip, Elevated nostrils, High arched palate,
Removal of the adenoids
Surgical removal of the adenoids is a procedure called adenoidectomy.
Adenoids may be removed if they become infected, causing symptoms such as excessive mucus production. Studies have shown that adenoid regrowth occurs in as many as 20% of the cases in which they are removed.
