Jaw cysts - these are the most common lesions of the jawbones.Cysts of the jaw called a cavity whose walls are composed of fibrous tissue, and the inner surface - from the epithelium.In such a cyst cavity contains either opalescent or clear liquid.


Today there are many types of jaw cysts, which now will be discussed.

primordial cyst (keratokista) is a common tumor, which occurs in the third molar, or the angle of the mandible.Sometimes this cyst occurs in the place where there is no tooth.Such mandible cyst has thin fibrous walls, as well as squamous epithelium, which lines the inner surface thereof.The content of this formation resembles cholesteatoma.Keratokisty there are also single-chamber and multi-chamber.Very often they are combined with many other malformations that leads (after removal of cysts of the jaw) to periodic relapses.

radicular cysts of the jaws up 80% from all cystoid abnormalities of the jaw.These cysts are found in the upper jaw in two times more often than on the bottom.Preceded by the formation of a chronic radicular periodonit.Typically, the diameter of the upper jaw cysts is 0.5-2 cm, but there are also cases when the cyst reaches three centimeters or more.In the period of acute inflamed tumor, and its cells giperplaziruyutsya that can cause reticulation processes.This symptom is jaw cysts characteristic only for cystoid formations radicular type.

impacted tooth cyst (follicular cyst) is localized in the alveolar region of the jaws.In the cavity of such tumors are one or more teeth in its infancy.There are situations when the cyst cavity contains the teeth and form.

retromolar jaw cyst refers to a variety of eruption cysts.It occurs due to chronic inflammation in periodontal tissues that are caused by difficult dentition, particularly wisdom tooth.Diagnosis of the formation confirmed by using X-ray examination.Treatment of jaw cysts of this nature - only surgical.

cyst incisive opening (incisive canal) is an epithelial neoplasm neodnogennym, which is formed from the remnants of epithelial tissue nasopalatine duct.Such localized cyst usually over maxillary incisors (in alveolar arcing).Quite often such maxillary cyst mistaken for radicular cyst.Treatment of this education is to remove the jaw cysts by cystectomy.

Cholesteatoma is a jaw tumor cystoid formation, the shell is sent to the epidermis.As for content, it has a kind of pasty mass.This mass consists of cholesterol crystals and horny masses.The symptoms of cysts of the jaws of this nature are almost identical with the clinical manifestations of all other types of cystiform formations.

aneurysmal bone cysts are rare.The etiology and pathogenesis of these tumors has not been studied.They usually occur in the intact (healthy) teeth on the lower jaw in pubertal and prepubertal.Such lower jaw cysts contain hemorrhagic fluid or blood.In the early stages of development of cysts, patients do not show any complaints, which can not be said about running formations.The main symptom of aneurysmal cyst of the jaw type (in the later stages) is a deformity of the lower jaw ( "inflation").

nasoalveolar and globular-maxillary cysts are formed from epithelium at the junction of the upper jaw, and the intermaxillary bone.These tumors contain a yellowish liquid that has no cholesterol.

Traumatic cysts of the jaws are very rare.They are non-epithelial cysts.These structures most often occur in the lower jaw.The initial stages occur without any symptoms, and are diagnosed by chance.The pathogenesis of traumatic mandibular cysts is unknown.These tumors may not have liquid contents, or be filled with hemorrhagic fluid.Removing jaw cysts of this type carried out by cystotomy or husking.

Clinical manifestations and common symptoms of jaw cysts

In the early stages of development of jaw cysts subjective clinical manifestations are absent.With the growth of tumors appears painful rounded protrusion.With ortopantomogrammu can well see the spherical cavity of the cyst and its each circuit.As soon as there are complications purulent character, the symptoms of jaw cysts are attached signs of osteomyelitis.

Treatment of jaw cysts

In general, treatment of jaw cysts is surgery.Through cystotomy cystectomy and, at times, the root cyst can be treated without surgery.But festering formations, as well as their complications require immediate incision and drainage cavity.

main objective of surgical treatment is to keep the teeth are cysts in the area, and the restoration of the disturbed functions.Cystectomy (complete removal of the cyst of the jaw with sewing the wound) makes it possible to simultaneously perform a resection of the tooth root.This procedure is carried out, if the root of the tooth more than 1/3 immersed in a cavity tumors.If the dive quite deep, the teeth (in terms of functionality) become unusable, and early fall.

cystotomy - a common method of treatment of jaw cysts, which are removed only when the front wall of Education, and the latest report from the oral cavity.

Plastic cystectomy - surgery method, which is carried out at the complete removal of the cyst shell without sewing wounds.Apply this method rarely - in the treatment of festering zubosoderzhaschey keratokisty or cysts.

Two-stage operation - a combination of two types of surgery: cystotomy and cystectomy.Such an operation is non-traumatic and conservation.It can be performed on an outpatient basis.It allows you to save the dimensions and contours of the jaw, in spite of the size of the defeat.Two-stage operation ensures complete recovery of the patient.
