Where are the 5 tonsils located?

The tonsils (palatine tonsils) are a pair of soft tissue masses located at the rear of the throat (pharynx). Each tonsil is composed of tissue similar to lymph nodes, covered by pink mucosa (like on the adjacent mouth lining).

How many types of tonsils are there?

four different typesThere are four different types of tonsils: palatine, pharyngeal (commonly referred to as the adenoid), lingual and tubal. Together these four types of tonsils make up what is called Waldeyer's ring.

Where are tonsils found?

The tonsils are part of MALT ( mucosa associated lymphoid tissue ). MALT can also be found in the bowel, in Peyer’s patches. In general MALT is relatively undeveloped at birth with low cellularity. Tonsils start to develop around 14-15th week of embryonic life, while germinal cenres are absent at this stage. Palatine tonsils and tonsillar fossa are believed to be the derivatives of the 2nd pharyngeal pouch. The epithelial lining proliferates and forms buds, which form the primordium of the palatine tonsil.

What is the germinal center of a tonsil?

In addition, the center of each of these nodules is densely packed with lymphocytes , and is referred to as the germinal center. The tonsillar crypts (except the pharyngeal tonsil) will penetrate from the surface, almost down to the very center of the tonsil follicle. The luminal surfaces of the tonsils are coated in non-keratinizing stratified squamous epithelium, which is the same tissue of the surrounding oropharynx.

What is the best treatment for tonsillitis?

The most common way to treat tonsillitis is with anti-inflammatory drugs such as ibuprofen, or if bacterial in origin, antibiotics, e.g. amoxicillin and azithromycin. Surgical removal ( tonsillectomy) may be advised if the tonsils obstruct the airway or interfere with swallowing, or in patients with severe or recurrent tonsillitis. However, different mechanisms of pathogenesis for these two subtypes of tonsillar hypertrophy have been described, and may have different responses to identical therapeutic efforts. In older patients, asymmetric tonsils (also known as asymmetric tonsil hypertrophy) may be an indicator of virally infected tonsils, or tumors such as lymphoma or squamous cell carcinoma .

Why is it important to document tonsil size and tonsil grading?

In clinical settings, it is important to document tonsil size and tonsil grading, as well as perform reliable monitoring. The grading scale of tonsils helps the clinicians to record the change in the tonsil size and communicate accordingly.

Why is tonsil grading important?

In clinical settings, it is important to document tonsil size and tonsil grading, as well as perform reliable monitoring. The grading scale of tonsils helps the clinicians to record the change in the tonsil size and communicate accordingly. Various grading systems may provide results that may be interpreted differently by the users. This makes the assessment of tonsil size by using tonsil grading system unreliable. Due to the variability in tonsil grading systems, there can be confusion in communicating the tonsil size. Hence, it is necessary to compare the existing tonsillar grading scales and to check the reliability and reproducibility. However, the reliability of this needs to be studied. Due to recurrent infection or as a part of generalized lymphoid hypertrophy, tonsils undergo hypertrophy. There is a good correlation between clinical tonsil grade and tonsil volume in snorers and obstructive sleep apnea.

Overview

Structure

Humans are born with four types of tonsils: the pharyngeal tonsil, two tubal tonsils, two palatine tonsils and the lingual tonsils.
The palatine tonsils tend to reach their largest size in puberty, and they gradually undergo atrophy thereafter. However, they are largest relative to the diameter of the throat in young children. In adults, each palatine tonsil normally measures up to 2.5 cm in length, 2.0 cm in width and 1.2 c…
