2. Diseases and conditions in which disrupted air pneumatic holding Waterways (anatomical changes):

1. The main functions of the eustachian tube. 2. Mechanism (pathogen (Greek pathos - suffering + genes - produce) - any microorganism or any other environmental factor capable of causing damage or disease (pathological condition) of another organism. Ithout) evstahiita development. 3. Causes evstahiita. 4. Factors contributing to the development of evstahiita. 5. Symptoms of acute evstahiita. 6. Symptoms of chronic evstahiita. 7. On what basis are diagnosed "evstahiit"?
Eustachian (aka auditory) tube connects the nasopharynx and tympanic cavity of the middle ear. It has a length of about 3-4 cm, and the diameter of its lumen is only 1-2 mm. Eustachian tube: Vent or barofunction provides sound conduction. It consists in maintaining equal pressure on both sides of the tympanic membrane, i.e. balancing the pressure in the tympanic cavity with air pressure. shingles pictures This is necessary for the proper sound conduction. For example, if the atmospheric pressure increases, the air flows through the auditory tube of the nasal cavity in the drum, and if reduced - in the opposite direction - from the tympanic cavity in the nasopharynx. When swallowing the auditory tube lumen expands and air from the nasopharynx misses the tympanic cavity. If the ventilation function of the auditory tube is broken, there is a change in pressure inside the tympanic cavity. shingles pictures At the same time suffers sound conduction and therefore sounds distorted and reduced hearing. The drainage function. It consists in the removal of secretions from the tympanic cavity mucosa. shingles pictures The protective function. This function is provided shingles pictures by the fact that the mucus that stands mucous glands of the auditory tube, has antibacterial properties, and contains local protection factor - Ig is special protective proteins produced by B lymphocytes circulating in body fluids and possess the ability to recognize antigens, contact them and neutralize them. Provide specific humoral immunity. A.
2. Mechanism (pathogen (Greek pathos - suffering shingles pictures + genes - produce) - any microorganism or any other environmental factor capable shingles pictures of causing damage or disease (pathological condition) of another organism. Ithout) evstahiita development.
Because ET is very narrow, it is at its inflammation, swelling, or minor anatomical changes patency pipe is broken. Admission of air into the tympanic cavity decreases shingles pictures due to compression of the pipe mouth and the air remaining therein shingles pictures before gradually absorbed, and accordingly the pressure shingles pictures in the cavity is reduced. In this retracted eardrum, a sensation of noise, nasal ear, hearing impairment. Moreover, in low-pressure air and pressure decrease edematous fluid exudate in the tympanic cavity, which promotes inflammation top. With long-term shingles pictures abuse of the tympanic cavity ventilation inflammation can purchase purulent with the development of adhesions in the middle ear. Thus, the process is almost shingles pictures the same as in the inflammation of the middle ear, but with advantage the changes shingles pictures in the auditory tube.
1. Infection when the inflammatory process proceeds from the cavity of the nasopharynx to the mucosa of the auditory tube: Infectious Diseases: SARS, measles, infectious mononucleosis, diphtheria, scarlet fever, etc. Acute and chronic inflammation of upper respiratory tract: rhinitis, sinusitis, pharyngitis, tonsillitis.
2. Diseases and conditions in which disrupted air pneumatic holding Waterways (anatomical changes): adenoids in children. Polypoid rhinosinusitis. Deviated septum. Deformation shingles pictures of inferior turbinates. Benign tumors of the nasopharynx.
4. Factors contributing to the development of evstahiita: Reduced body resistance caused by, for example, vitamin deficiency, or concomitant diseases (diabetes mellitus). Coughing and sneezing, which contribute to an increase in pressure in the nasopharynx and get infected mucus in the Eustachian tube. Incorrect otsmarkivanie (once both halves of the nose). Children's age. Children often suffer greatly evstahiitom. This is due to the fact that in childhood auditory tube is shorter and wider than the adult, therefore the inflammatory process becomes easier since it nasopharynx.
5. Symptoms of acute evstahiita. The main complaint - that feeling of fullness, pressure and noise in the ear. Feeling as if the liquid is poured in your ear, especially when changes in head position. Syringmus - increased shingles pictures perception of their own voice in the affected ear, the sound resonates like. Ear pain of varying severity. Heaviness in the head. Perhaps a slight hearing loss, which improves when yawning or swallowing shingles pictures saliva. This is due to the fact that when such action opens the lumen of the auditory tube. That's why airplanes shingles pictures recommend sucking lollipops. May be a small rise in body temperature. General state of the organism when Eustace is not affected much.
All these unpleasant shingles pictures sensations h
