Ultrasound of the salivary glands: normal, holding


The salivary glands of the person represented by the parotid, submandibular and sublingual glandular formations located symmetrically on both sides of the head. From the outside through the sensor are investigated submandibular the parotid gland, and lymph nodes, and oral cavity inspected submandibular, and sublingual glandular formation.

What is an ultrasound of the salivary glands? It is a diagnostic method that allows using ultrasound to determine the condition of the body and its surrounding tissue. Unlike palpation, that is, using probing, research, in which you can only determine the growth of an organ, ultrasound gives the opportunity to differentiate or distinguish tumor formation and inflammation in the body.

  • determination of the presence of obstruction in the ducts or the lack of it;
  • neoplastic diseases both benign and malignant. It is known that most tumors located in this area are benign, a smaller proportion of the malignancy. The minimum proportion in the metastases from other organs. To determine the nature of the tumor in the body it is necessary to conduct this method of research;
  • congenital anatomical anomalies;
  • degenerative tissue damage, such as sialadenosis and silozi.

Principles of the procedure

The advantage of this method is the lack of special requirements for starting the procedure. This means that before the examination the patient should not receive special training.

The only thing he needs to do is worry about the cleanliness of the oral cavity. This is necessary for proper operation of the sensor, which during the test is in the external environment, and in the oral cavity.

During the ultrasound examination, attention is paid to several parameters, each of which has its own value. Of greatest importance are:

  • dimensions;
  • location;
  • the contours;
  • echogenicity or metric that determines the density of the fabric.

To make conclusions about the results of the study, it is necessary to know what is the normal ultrasound pattern of the glandular organs. In a healthy person, they have a smooth, clearly visualized by the contours, the structure is homogeneous. The salivary ducts to determine not always possible.

The dimensions of each gland is different. So, the parotid has a length of from 40 to 50 mm and a width of from 32 to 42 mm. While the submandibular gland has other parameters: its length from 29 to 38 mm, thickness from 11 to 17 mm, and the anteroposterior size of 30 to 40 mm.

After receiving the Protocol of the study, the experts draw their own conclusions. From estimated size. The increase in cancer may indicate an inflammatory process or tumor formation. To tumor characteristic is the change in the structure of the body, it becomes heterogeneous.

Quite often you can identify hotspots of vascularization germination or the formation of blood vessels. When cysts form in this region during the ultrasound are determined by the cavity formation, filled with fluid. Their sizes may be different.

On the development of the obstructive process, says the expansion of the salivary ducts, as well as the definition of hyperechoic inclusions. So, for the diagnosis of the pathological process in the salivary glands is often necessary to conduct an ultrasound, the results of which should be evaluated by an expert.
