Due to their strategic location, this tissue frequently demands more blood to assist in immune responses to common illnesses like viral upper respiratory infections. Tonsils also have specialized surface antigen capture cells called M cells that allow for the uptake of antigens produced by pathogens. The development of the palatine tonsils begins during the fourteenth week of gestation.
Crypts proliferate into the connective tissue and are infiltrated by T-lymphocytes at week The blood supply of the palatine tonsils derives from vasculature that branches off several major vessels, all are primarily tributaries of the external carotid artery. The dorsal lingual artery, ascending palatine artery, the tonsillar branch of the facial artery, ascending pharyngeal artery, and lesser palatine artery all provide oxygen and other nutrients to the palatine tonsils.
Venous drainage of the palatine tonsils occurs by the peritonsillar plexus of veins. This plexus drains into the pharyngeal and lingual veins, and these veins ultimately drain into the internal jugular vein. The palatine tonsils drain to the jugulodigastric node, a node of the deep cervical lymph nodes, located inferior to the angle of the mandible. The innervation of the palatine tonsils is provided by the lesser palatine nerve which arises from the maxillary division of the trigeminal nerve and the tonsillar branches of the glossopharyngeal nerve.
Tonsillectomy is a surgical procedure where the palatine tonsils are excised from the tonsillar fossa. Tonsillectomy should be considered in patients who [7] [8] [7] :. Indications for tonsillectomy include a variety of hyperplastic and neoplastic processes.
Some of these include hyperplasia of adenotonsillar tissue associated with obstructive sleep apnea, failure to thrive, or abnormal dentofacial growth. The most frequent complication of a tonsillectomy is post-operative hemorrhage, which is responsible for the majority of post-tonsillectomy fatalities. Significant risk factors for post-operative hemorrhage include older age, a history of chronic tonsillitis, excessive intraoperative blood loss and elevated mean arterial pressure.
The glossopharyngeal nerve innervates the posterior one-third of the tongue and provides general sensation and taste.
The nerve travels past the palatine tonsils and has the potential to be stretched or injured during a tonsillectomy. Consequences of this injury could manifest as a reduction or loss of general sensation or taste to the posterior third of the tongue.
It is an overlooked cause of sore throat because your lingual tonsils are not as noticeable in a physical examination as your palatine tonsils. In this study, two-thirds of people with lingual tonsillitis previously had a tonsillectomy or adenoidectomy removal of adenoids.
Signs of lingual tonsillitis include the following:. A study published in Clinical Case Reports discusses lingual tonsillar hypertrophy, or swollen lingual tonsils, and its unique mix of symptoms.
It is often asymptomatic. But it can sometimes become apparent if you have difficulty swallowing, have a persistent cough, have a sensation of a lump in your throat, notice a change in your voice, have a difficult time getting intubated, or experience obstructive sleep apnea OSA. Findings concluded that an elevated body mass index and a positive result of laryngopharyngeal reflux were associated with lingual tonsillar hypertrophy for people experiencing obstructed sleep apnea.
Although your lingual tonsils may have helped your body fight off infections when you were a young child, when your tonsils themselves become frequently infected, it may be time for their removal. Individuals of any age can have their tonsils removed.
Your medical or dental professional might recommend the procedure if you develop reoccurring infections or if swollen lingual tonsils cause other problems, such as snoring or sleep apnea. Like the other groupings of lymph nodes that make up your lymphatic system, your lingual tonsils play an essential role in defending your body against infections.
But repeated bouts of tonsillitis or symptoms that arise from lingual tonsil hypertrophy can affect your quality of life and lead you to consider removing them, especially if you're an adult. What's most important is that you schedule an appointment with your primary care doctor, who may refer you to an Ear, Nose, and, Throat Specialist ENT.
They can help you figure out the source of your discomfort and put your mind at ease. Most importantly, they'll help you feel confident in whatever decision you make for managing your lingual tonsils.

Technically, there are three sets of tonsils in the body: the pharyngeal tonsils, commonly known as adenoids, the palatine tonsils and the lingual tonsils, which are lymphatic tissue on the surface tissue of the base of the tongue, according to Encyclopedia Britannica.
When people refer to tonsils, though, they are usually talking about the palatine tonsils. These tonsils are oval, pea-sized clusters of lymph cells in the pharynx at the opening of either side of the throat. Though they may seem large in children, the size of the tonsils tends to get smaller when a person becomes an adult.
Though small and seemingly useless, tonsils have several uses. The tonsils prevent foreign objects from slipping into the lungs. Think of them as goalies for the throat. They also filter bacteria and viruses.
On top of all that, they produce white blood cells and antibodies, according to the Mayo Clinic. According to the American Academy of Otolaryngology, these bumps on the back of the throat are the "first line of defense as part of the immune system. Lymph is a clear and colorless fluid; the name comes from the Latin word lympha , which means "connected to water," according to the National Lymphadema Network.
Often, the most common problem with the tonsils is inflammation, called tonsillitis.
