Chronic tonsillitis: treatment methods

Tonsils

(
tonsillae
) - accumulation of lymphoid tissue in the thickness of the mucous membrane at the border of the nasal, oral cavities and pharynx. Depending on the location, there are palatine tonsils (tonsillae palatinae), pharyngeal tonsil (tonsilla pharyngea), lingual tonsil (tonsilla lingualis), tubal tonsils (tonsillae tubariae). They form the main part of the Pirogov-Waldeyer pharyngeal lymphoepithelial ring (Fig. 1). In addition to the tonsils, this ring includes accumulations of lymphadenoid tissue embedded in the mucous membrane of the outer parts of the posterior wall of the oropharynx, parallel to the velopharyngeal arches, the so-called. lateral ridges of the pharynx, as well as single follicles scattered in the mucous membrane of the pharynx (folliculi lymphatici pharyngei). The tonsils are part of a single lymphoepithelial apparatus that develops in the mucous membrane of the digestive, respiratory and genitourinary systems in the form of solitary lymphatic follicles (folliculi lymphatici solitarii) or group lymphatic follicles (folliculi lymphatici aggregati). During the process of phylogenesis, the accumulation of lymphoid tissue in the mucous membrane at the border of the pharynx and the oral and nasal cavities in the form of tonsils was first noted in mammals.

Schematic representation (sagittal section) of the nasal, oral cavities and pharynx: 1 - lingual tonsil; 2 - palatine tonsil; 3 - pharyngeal (nasopharyngeal) tonsil; 4 - tubal tonsil; 5 - scattered lymphatic follicles in the mucous membrane of the posterior pharyngeal wall. Rice. 2. Schematic representation of the anatomical variants of the palatine tonsils (according to K. A. Orleans with some modifications): 1 - free tonsil protruding into the pharynx; 2 — the mouth of the accessory intrapalatal tonsil; 3 - additional intrapalatal tonsil; 4 - sine of Turtual; 5 - muscular wall of the tonsil fossa; 6 - tonsil capsule; 7 - triangular fold; 8 - tonsil, pinched in the palatine arches; 9 - upper corner of the tonsil fossa; 10 - large palatine lobule. The formation of the tonsils occurs during the prenatal period of development in the area of ​​the head intestine.
There is a certain sequence in their formation and development. First of all, the palatine, then the pharyngeal, lingual and tubal M. appears. The palatine M. are laid at the bottom of the second gill pouch at the end of the 2nd - beginning of the 3rd month in the form of a protrusion of the endoderm. The latter gives rise to the epithelial cover and crypt system of M. Lymphoid tissue of M develops from the surrounding mesenchyme. At the 8th month of intrauterine development of the fetus, lymphatic follicles of M. (folliculi lymphatici tonsillares) appear, and by the end of the 1st month of the child’s life, centers appear in them reproduction (centrum multiplicationis). Pharyngeal M. is formed in the 3rd-4th month in the form of 4-6 folds of the mucous membrane in the area of ​​the pharyngeal vault. At the 6th month, lymph follicles appear for the first time, and at the 2nd - 3rd month after birth, reproductive centers appear. Lingual M. is formed as a paired formation in the 5th month in the form of longitudinal folds of the mucous membrane of the root of the tongue. At the 6th month, the folds fragment, at the 7th month, follicles appear, and at the 3rd - 4th month after birth, reproductive centers appear. Tubal M. are formed in the 8th month in the form of separate accumulations of lymphocytes around the pharyngeal opening of the auditory tube. By the birth of a child, follicles are formed, and in the first year of life, reproductive centers are formed.

Complications

Chronic tonsillitis is very dangerous due to rapidly occurring complications. The most severe of them are heart disease - myocarditis, inflammation of the joints - rheumatism and serious kidney damage - glomerulonephritis.

Some toxins that are produced by microbes in the tonsils and then enter the bloodstream can damage cartilage and ligament tissue. The result is inflammation and pain in the muscles and joints. Other toxins often cause persistent fever, changes in blood tests, fatigue, depression, and severe headaches.

Chronic tonsillitis can affect the functioning of such a vital organ as the heart. The tonsils are often parasitized by group A beta-hemolytic streptococcus, the protein of which is very similar to the protein found in the connective tissue of the heart. Because of this, the immune system can show retaliatory aggression not only to the emerging streptococcus, but also to its own heart. As a result, heart rhythm disturbances, heart valve prolapses, and even the development of severe myocarditis and bacterial endocarditis occur.

For the same reason, articular surfaces and kidney tissue are at great risk. Unfortunately, the development of diseases such as rheumatoid arthritis and glomerulonephritis is extremely high.

Due to the fact that the source of infection remains in the tonsils for a long time, a distortion of the body’s reactivity occurs, resulting in allergic changes. In some cases, just one course prescribed by a doctor can get rid of itching and allergic rashes, and in some cases stop the development of bronchial asthma attacks.

Anatomy

Palatal

The tonsil is a paired formation located in the fossa of the tonsils (fossae tonsillares) of the lateral walls of the pharynx between the palatoglossus arch (areus palatoglossus) and the velopharyngeal arch (areus palatopharyngeus). It has an oval shape, its long axis runs from top to bottom and somewhat from front to back. In a newborn, the size of the palatine m. in the vertical direction is 10 mm, in the transverse direction 9 mm, thickness 2.1 mm; in an adult, respectively, 15-30 mm, 15-20 mm, 12-20 mm. In the palatal M., two surfaces are distinguished: internal (free) and external, facing the wall of the pharynx. The inner surface is uneven, covered with a mucous membrane, has 8-20 irregularly shaped tonsillar dimples (fossulae tonsillares), which are the mouths of tonsillar crypts (cryptae tonsillares), which, branching, penetrate the thickness of the palatine membrane. The crypts increase the free surface area of ​​each palatine membrane up to 300 cm2. When swallowing, the palatine membranes are slightly displaced, and their crypts are freed from their contents. The outer surface of the palatine membranes is covered with a capsule (capsula tonsillae) up to 1 mm thick; on it lies a layer of loose paratonsillar tissue, the edges go down to the root of the tongue, in front it communicates with the tissue of the palatoglossal arch, at the top - with the submucosa of the soft palate. In an adult, the distance to the internal carotid artery from the upper pole of the palatine M. is 28 mm, from the lower pole 11-17 mm, to the external carotid artery 41 mm and 23-39 mm, respectively. The upper corner of the M.'s fossa remains free and is called the supratonsillaris fossa. Sometimes there is an additional palatine M.—the palatine lobe of the palatine M., the edges of which can extend deep into the soft palate and not have a direct connection with the main palatine M. (Fig. 2). In these cases, it represents an additional intrapalatine M. (tonsilla intrapalatina accessoria), the edges usually contain a deep branched crypt - the sinus of Tourtuali, which plays a certain role in the pathology of the M.

Pharyngeal

M. (syn.: nasopharyngeal M., Lushka's tonsil, third M.) is located on the border of the upper and posterior walls of the pharynx (see), has the appearance of a round-shaped plate with 4-8 folds of the mucous membrane diverging on its surface, protruding into the cavity nasopharynx. The pharyngeal M. is well developed only in childhood; with the onset of puberty, its reverse development occurs.

lingual

M. (syn. fourth M.) is located in the region of the root of the tongue (see), occupying almost the entire surface of the root of the tongue. Its shape is often ovoid, the surface is uneven, and lingual follicles (folliculi linguales) are located on the mucous membrane, divided by grooves into a number of folds. M.'s crypts are shallow, at the bottom of many crypts the excretory ducts of the salivary glands open, the secretion of which helps to wash and cleanse the crypts. In a newborn, the lingual M. is well developed, its longitudinal size is 6 mm, transverse 9 mm. After 40 years, a gradual reduction of lingual M occurs.

Pipe

M. is a paired formation, which is an accumulation of lymphoid tissue in the thickness of the mucous membrane of the nasopharynx at the pharyngeal opening of the Eustachian tube (see Auditory tube).
In a newborn, the tubal M. is well defined, approx. 7.5 mm, diameter approx. 3.5 mm. Tubal M. reaches its greatest development at 5-7 years of age; later it gradually atrophies and becomes almost invisible. Rice.
3. Schematic representation of the blood supply to the palatine tonsil: 1 - external carotid artery; 2 - maxillary artery; 3 - descending palatine artery; 4 - ascending pharyngeal artery; 5 - ascending palatine artery; 6 - facial artery; 7 - lingual artery; 8 - superior thyroid artery; 9 - common carotid artery; 10 - internal carotid artery; 11 - palatine tonsil. The blood supply to the tonsils of the lymphoepithelial pharyngeal ring, including the palatine M. (Fig. 3), is carried out by arterial branches (aa. tonsillares), extending directly from the external carotid artery or its branches: the ascending pharyngeal (a. pharyngea ascendens), lingual (a. lingualis), facial (a. facialis), descending palatine (a. palatina descendens). M.'s veins are formed in the parenchyma, accompany the arteries and flow into the pharyngeal venous plexus (plexus venosus pharyngeus), lingual vein (v. lingualis), and pterygoid venous plexus (plexus venosus pterygoideus). M. does not have afferent lymphatic vessels. The draining lymphatic vessels flow into the lymph nodes: parotid, retropharyngeal, lingual, submandibular. M.'s innervation is carried out by the branches of the V, IX, X pairs of cranial nerves and the cervical part of the sympathetic trunk. In the subepithelial layer of connective tissue septa, M.'s parenchyma, there are individual nerve cells, their clusters, pulpy and non-pulpate nerve fibers, various types of nerve endings, and extensive receptor fields. The blood supply and innervation of the muscle change with age.

Forms of the disease

  • recurrent form, that is, with frequently recurring sore throats;
  • protracted form, when the inflammatory process in the palatine tonsils is characterized by a sluggish and prolonged course;
  • compensated form, when episodes of sore throat and exacerbation of tonsillitis are not observed for a long time.

Chronic tonsillitis is the most common disease among all diseases of the pharynx and one of the most common diseases of all ENT organs, along with such a diagnosis as acute sinusitis.

Chronic tonsillitis can affect both adults and children, from the moment the palatine tonsils begin to develop (from 2-3 years). Moreover, the incidence of this disease in childhood is much higher.

Some respiratory diseases can also be classified as social diseases. For example, sinusitis and tonsillitis are among them. Poor environment, stress, lack of sleep, overwork, monotonous and poor nutrition, as well as poor heredity are predisposing factors to the development of the disease.

Histology

4. Diagram of the structure of the palatine tonsil: 1 - capsule; 2 - tonsil crossbars; 3 - lymphatic follicles of the tonsil; 4 - tonsil parenchyma; 5 - multi-row squamous epithelium of the pharynx surface of the tonsil, continuing into the crypts; 6—exit openings of tonsil crypts. M. consist of stroma and parenchyma (Fig. 4). The stroma forms the connective tissue framework of M., formed by collagen and elastic fibers. They form a capsule (shell) around the M.’s circumference, from which connective tissue crossbars (trabeculae) extend into the M.’s depth. In the thickness of the crossbars there are blood and lymphatic vessels and nerves of the M., and sometimes the secretory sections of small salivary glands. M.'s parenchyma is represented by lymphoid tissue (see), the cellular basis of the cut is lymphocytes, macrophages, and plasma cells. Elements of lymphoid tissue form in places round-shaped clusters—follicles, which are located parallel to the epithelium along the free surface of the tumor and along the crypts. The centers of the follicles can be light - the so-called. reproduction centers, or reactive centers. The free surface of the M. is covered with a mucous membrane with multi-row squamous non-keratinized epithelium. In the area of ​​the crypts it is thinner and in places broken; the basement membrane is also fragmented, which contributes to better contact of the lymphoid tissue with the environment.

Types of tonsil removal surgeries

Classical

The surgeon installs a mouth retractor and separates the tonsil tissue along with the capsule from the surrounding tissues in a “blunt” way using a raspator. The bleeding is stopped, the vessels are cauterized with an electrocoagulator or laser. The whole process takes from 15 to 40 minutes.

Electrocoagulation

Cryodestruction

Tonsils are frozen with liquid nitrogen. As a result, they become pale, flat and hard, and after a day they die and are gradually rejected. The method is recommended for patients with an increased risk of bleeding (thrombocytopenic purpura, hemophilia, etc.), severe heart failure and endocrine pathology.

Important! The cryosurgical method is used in a series of procedures lasting up to 1.5 months. During this time, a relapse of the disease is possible if not all of the tonsil tissue has been destroyed. Cryosurgery is used when classical surgery is not possible.

Ultrasonic destruction

High-frequency sound vibrations warm up the tissues to prevent bleeding. Unlike exposure to liquid nitrogen or electricity, surrounding tissue is almost not damaged. Ultrasound method is one of the least traumatic.

Radio wave destruction

A probe is installed inside the tonsils, which generates radio waves. They evaporate the water from here and cause scarring. Ablation can be repeated several times. Anesthesia is not needed here - only local anesthesia or light sedation. Recovery is quick, but radical tonsil removal is almost impossible. Therefore, radio wave therapy is used for their hypertrophy, but not for chronic tonsillitis, when radical intervention is required.

Cold plasma destruction

A relatively new method of removing tonsils. It is based on the property of cold plasma (radio frequency energy converted into ionic dissociation) to separate molecular bonds in tissues without releasing thermal energy. Plasma is called cold because it causes minimal heating of the tissue, which means that pain after surgery will be insignificant, recovery will be easy and quick. The method is low-traumatic and can be used for partial or complete removal of tonsils.

Laser removal

Laser tonsillectomy can be complete or partial (with cutting of the upper layers of the tonsils). Different types of laser are used - carbon, infrared, etc. Only pathological tissues are removed, and healthy ones are not affected. Other advantages include immediate separation of the tonsil from the underlying tissues with coagulation of blood vessels, which reduces the risk of bleeding and infection.

Physiology

Having a common structure with other lymphatic organs (see Lymphoid tissue), M. perform similar functions—hematopoietic (lymphocytopoiesis) and protective (barrier). The follicular apparatus, embedded in the mucous membranes, is a lymphoid barrier, biol, whose role is the neutralization of toxic substances and inf. agents that enter mucous membranes from the environment. In human M. there are both thymus-dependent and thymus-independent populations of lymphocytes (see), which carry out reactions of both cellular and humoral immunity (see). M. are a peripheral organ of immunity that has a certain uniqueness. Firstly, they have a lymphoepithelial structure, secondly, they are the entrance gates for microbial antigens and, thirdly, they lack lymphatic vessels. It is known that M. contain cells that produce antibodies of the IgE class, which are believed to perform a protective function. It has been shown that lymphocytes of M.'s lymphoid tissue produce interferon (see), which is a nonspecific factor of antiviral immunity.

Research methods

Rice.
5. Examination of the tonsils by rotating them with a spatula: 1 - left palatine tonsil (the right one is symmetrical to it in the figure) with the open mouths of the lacunae from where their contents emerge; 2 - palatoglossal arches; 3 - spatulas. The tonsils can be examined during posterior rhinoscopy (see) - pharyngeal and tubal, during pharyngoscopy (see) - palatine, lingual, lateral ridges and lymphoid follicles (granules) of the posterior pharyngeal wall. The method of palpation and probing of lacunae is used. The palatal m. are examined by rotating or dislocating them using two spatulas, and the contents of the lacunae and its nature are determined. There is usually no content in the M. lacunae of a healthy person. The M.'s rotation is performed with a tonsillorotator or a wire spatula, which is pressed on the palatoglossus (anterior palatine) arch, which entails the rotation of the M. with the free surface forward. In this case, the mouths of the lacunae open and their contents are squeezed out - plugs, pus (Fig. 5).

Pathology

Developmental anomalies

. Developmental anomalies include the palatine lobule and the accessory palatine M. Sometimes, instead of one palatine M, two M develop on each side. Additional lobules hanging on the stem have been described. As a rule, these anomalies do not require treatment.

Damage

— burns, wounds of M. — are rare in isolation; more often they are combined with internal and external injuries of the pharynx (see).

Foreign bodies

- most often fish bones, which can penetrate into the muscle tissue, causing pain when swallowing. Remove them with tweezers or special forceps. After removal, a disinfectant rinse and a gentle diet are recommended for one to two days (see Foreign bodies, pharynx).

Diseases

6. Schematic representation of the first stage of the tonsillotomy operation: the hyperplastic area of ​​the left palatine tonsil is captured by the tonsillotomy ring. Acute disease of palatine M.— acute

tonsillitis
, or tonsillitis
(see). Hron, inflammation of the palatine M.—tonsillitis (see). Hyperplasia of the palatine membranes occurs in children; there are no signs of inflammation. M. are only increased in size. If hyperplasia causes difficulty breathing or swallowing, children undergo surgery - tonsillotomy (Fig. 6), i.e. partial cutting off of the protruding part of the M. Before the operation, a full wedge examination is necessary.

The operation is low-painful, most often performed without anesthesia, on an outpatient basis, with a special instrument - a guillotine-shaped knife - tonsillotome, the size of which is selected according to the size of the removed muscle. Hyperplasia of the palatine muscles is in most cases accompanied by the proliferation of adenoid tissue of the nasopharynx, therefore tonsillotomy is often combined with adenotomy (see . Adenoids). Bleeding after tonsillotomy is usually minor and stops quickly. The child should remain under medical supervision for 2-3 hours. It is recommended to observe bed rest for 1-2 days, then semi-bed rest for 3-4 days. Food should be liquid and mushy, at room temperature.

Acute inflammation of the pharyngeal M., or acute adenoiditis

(see), observed mainly in children. In this case, the tubal M. may also be involved in the inflammatory process. Inflammation is catarrhal, follicular or fibrinous in nature. Due to the anatomical proximity of the mouth of the auditory tube, symptoms of tubo-otitis may occur (see).

Isolated disease of the lingual M. is much less common. It occurs in middle-aged and elderly people and may be accompanied by an abscess of the lingual M.; occurs with high fever, difficulty swallowing and speaking, and severe pain when protruding the tongue.

With angina of the lateral ridges of the pharynx, inflammation occurs in the lymphoid follicles scattered along the back wall and in the lateral lymphoid ridges (columns). Often a whitish dotted coating appears on individual follicles of the posterior pharyngeal wall.

A disease of the lymphoid tissue of the larynx is called laryngeal angina

; it is manifested by high fever, general malaise, sharp pain when swallowing food and palpating the larynx area. Plaques are often visible, and there may be swelling of the outer ring of the larynx (see Laryngitis).

In addition to the primary lesion of the tonsils, changes in the lymphoid tissue of the pharyngeal ring occur with blood diseases. With leukemia (see), infectious mononucleosis (see Infectious mononucleosis), lymphogranulomatosis (see), an increase in palatal M. can cause difficulty breathing and swallowing. Ulcerative changes in the palatine muscles, such as necrotizing tonsillitis, are also possible.

With syphilis, the palatine M. are affected in all stages of the disease. There are descriptions of hard chancroid M.: against a limited hyperemic background in the upper part of M. a hard infiltrate appears with painless erosion in the center, the edges soon turn into an ulcer with compacted edges and bottom; the lesion is unilateral, characterized by regional lymphadenitis (see). In stage II of syphilis, syphilitic tonsillitis occurs: round or oval plaques, separate and confluent, appear on the muscle, rising above the surface of the muscle, surrounded by a reddish rim, easily ulcerating; characterized by bilateral lesions; the entire M. is enlarged, dense, covered with plaque; Papules are found on the mucous membrane in the corners of the mouth, on the palatine arches, and along the edge of the tongue. In stage III, gumma can lead to the disintegration of M., which threatens bleeding from large vessels. Treatment - see Syphilis.

Primary M. tuberculosis is rare; its main symptom is difficulty swallowing and nasal breathing as a result of concomitant M. hyperplasia. Secondary M. damage can be observed in patients with pulmonary tuberculosis. Both forms can occur hidden, simulating a banal chronic condition, tonsillitis. Treatment - see Tuberculosis.

Features of the condition with enlarged tonsils without fever

Even at normal body temperature, but in the presence of pathological processes in the body, a person may feel completely unwell. Inflammation of the tonsils without fever, regardless of the cause, can interfere with a normal lifestyle and be accompanied by:

  • headache;
  • sore throat;
  • lack of appetite;
  • difficulty swallowing;
  • dryness and sore throat;
  • enlarged lymph nodes and pain on palpation;
  • fatigue, weakness, drowsiness, decreased performance, irritability.
