The main features of the transition purulent inflammation of the middle ear in the chronic condition are in the presence of a hole in the eardrum, as well as prolonged suppuration, more than two months, and when a bloody granulation offices.Chronic inflammation of the middle ear can be both local and simple uncomplicated inflammation.
simple uncomplicated inflammation affects the mucous membranes and does not apply to the bone.When local complicated forms may be affected bone that leads to the formation holestiatomy.Changes that occur in the middle ear may be characterized by infiltration cell round and then begins ulceration of the mucosa, and are thus formed strands and adhesions.Most local blood circulation can lead to tooth decay and bone tissue decay, and tooth decay is accompanied by the growth of granulation and such complications can occur with local complications of the middle ear.
Chronic inflammation of the middle ear characterized by a significant decrease in hearing, and this depends on
In that case, when the pus is delayed, the temperature may rise, there is heaviness in the head and begin ear and headaches.When the pus was aspirated, the perforation can be seen, and they may be in different parts of the eardrum.There may be a perforation edge and central, and central talking about defeat middle floor of the tympanic cavity, the edge perforation of the disease indicates the upper part of the tympanic cavity.It is known that the dome of the tympanic cavity filled tendon muscles, ligaments and bones, and a variety of circulatory disorders are expressed more strongly than mezotimpanitah.When epitimpanitah, you can see the complications of the brain, there are ulcers on the part of the meninges, with meningitis.
Chronic inflammation of the middle ear can last for years, if you do not spend quality treatment and at the same time they can be complicated by caries bone holestatomoy and polyps.A polyp is a simple granulation, myxoma, fibroids and angiofibroma and such complications can be observed in caries or caries bones that become recurrent in nature.On examination, a polyp has the form of red or pale pink mass, and they resemble raspberries and bleed on probing.To make a diagnosis of the polyp, it should be around vatnichkom or probe, do it, making sure it's consistency which is soft or hard.In that case, when it starts polyp suppuration, and it is mixed with blood, it then begins headaches and wherein amplified deafness.To polyps not fester or detained pus, or prevents the penetration of dosage forms in the ear, they are removed by a special loop.Polyps can be removed only when they do not have symptoms of fistula or fistula, so their removal in this case, can open maze purulent infections and in this position is better to conduct obschepolostnuyu operation.In that case, when a polyp is removed not completely, it may occur polyp recurrence and residues may grow again.
may develop cholesteatoma, a benign entity which can turn into malignant.It can fill the entire cavity in which there is, and it still captures the extra space and at the same time begins to penetrate the maze and can then reach critical vital organs, such as the large venous vessels, brain and meninges.This will cause intracranial complications and will be expressed in brain abscess, sepsis and meningitis otogennyh.Cholesteatoma is a cluster epidermoidalnyh masses and they are arranged in concentric layers, and their degradation products contain cholesterol, so called because it is a disease.Cholesteatoma itself resembles a bulb type and has a whitish formed shrapnellevoy perforation in the membrane due to the fact that the epidermal skin grows into the external auditory canal and is located in the middle ear space, and eridermalnye cells are killed and then converted to pasty mass.
treatment can be carried out via the attic of alcohol and it must be put into nadbarabannoe space and this is done through the perforation, while washing liquid jet should fall into the cavity, and there wash holesteatomnuyu mass.In the case where the remains of cholesteatoma, then, despite the fact that conservative treatment is carried out, should make obschepolostnuyu operation.The main aim of the operation is to combine in one cavity tympanic cavity and antrum process and wherein the first part of the operation is to cut production periosteum and the bone exposed.In the second part reveal the antrum and knocked part of the back wall, but only the external auditory duct, but the operation should take place in compliance with great caution due to the fact that close to the facial nerve passes.Thus, it must be concluded that chronic inflammation of the middle ear can cause deafness and the development of more serious disease.
