The parotid glands, the largest pair of salivary glands, are located behind the jaw angle directly below the ears and in front of them.
Sublingual glands and submandibular glands, two smaller pairs, are located deep into the mouth.
In addition to these major glands, many small salivary glands are distributed throughout the mouth. All glands produce saliva, which helps break down the food as part of the digestion process.

Several types of disorders affect salivary glands:
Salivary gland dysfunction
Grains of the salivary gland
Salivary gland infection
Salivary gland swelling
Ultrasound imaging is useful for the diagnosis of salivary gland diseases … for example, ultrasound images of Sjögren syndrome include heterogeneous areas with small or oval areas within the gland or less echo or no reflections, and there is usually an increase in flow the blood …
Sjogren syndrome is a long-term autoimmune disease that affects the salivary glands in the body, and the initial symptoms are dry mouth and eye
The dimensions can be measured and then ultrasonic ultrasound volumes accurately, front to rear, extension to gland depth, front scan.
Salivary stones can be diagnosed within salivary ducts and are the most common causes of salivary glands. These stones are the accumulation of crystalline saliva deposits. Sometimes salivary stones can prevent saliva flow. When saliva can not exit the ducts, it returns to the gland causing pain and swelling. .
The lymph nodes that are swollen in the neck are the most common, which is the lymph node and there is a large number of lymph nodes inside the parotid glands, the most common benign tumors in children is a tumor produced by the blood vessels / tumor Haemangioma, which is among the tumors of epithelial benign, (Pleomorohic adenoma) is the most common and arises from epithelial cells.
The first thing you should know about salivary glands is the difference between serous cells and mucous cells. … Each of the three glands has different proportions of these two types of cells. The parotid glands contain only the serous cells, the submandibular gland contains both mucous and serous cells.
The parotid gland is supplied with sensory nerves by the atrial nerve, and the large nerve nerve is supplied by the auriculotemporal and the great auricular nerve, the parasympathetic innervation to the parotid gland has a complex path, it begins with the glossopharyngeal nerve (cranial nerve IX)
Parasympathetic nerves of the parotid gland have a complex pathway, beginning with the pharyngeal nerve, the ninth nerve.
The treatment of salivary gland cancer depends on whether the cancer is low-grade (slow-growing) or high-grade (fast-growing). … Treatment is done by radiotherapy, rapid neutron radiotherapy for lymph nodes with cancer or chemotherapy according to degree of infection.
Symptoms of salivary gland tumor may include:
Swelling or swelling in or near the jaw or in your neck or mouth.
Numbness in the part of your face.
Weak muscles on one side of your face.
Persistent pain in the salivary gland area.
Problem opening your mouth on a large scale.
Parotidectomy is the surgical option (removal) of tumors, … Parotidomectomy is mostly performed by oral and maxillofacial surgeons and ENT specialists.
The benign lymphoma can become malignant in a few cases.
But nearly 75-85% of benign salivary gland tumors, there is no consistent correlation between the growth rate of the tumor and whether the tumor is benign or malignant …. Most benign parotid tumors appear as slow growth and often painless lumps in the tail of the gland Paraffin.
Cancer of the salivary gland is not fatal. If cancer is detected before it is spread, there is a 96% chance of living for many years to come.
Cancer of the salivary gland may be painful
Swollen mouth, cheek, jaw or neck. Pain in your mouth, cheek, jaw, or ear or neck does not disappear.
Case Report: This condition was suffering from tumors in the parotid gland, bilateral presence, and was removed from both sides, by detecting sonic waves on the neck and areas of the salivary glands, showing the presence of new tumors in the places of the parotid gland on both sides, and shows the presence of uterine on the right side 2×1 And 1.6×0.8×0.8cm. On the left side, 1.6×1.3×1.3cm, the tumor was spread on the right side of the ear and below the ear, and the tumor spread on the north side behind the ear and below the left jaw. The tumors were irregular in the tissue, It has been established that the tumors removed were benign of a multivariate type Forms can also be called mixed benign tumor pleomorphic adenoma,
This is the most common non-cancerous tumor in the salivary glands, often found in the tail of the parotid gland. The patient has removed this tumor because there is very little risk that it can develop into a cancerous tumor called multi-
Ex-pleomorphic adenocarcinoma) and the risk of transition over time, bilateral parotid gland tumors, ie on a few levels and occur between 1.3 and 3.5% …
Parasitic parathyroid or benign parotid gland tumors are very rare. Multiple polymorphism is the most common tumor in the parotid gland. Enucleation is associated with an endothelial discharge alone (8% -45%) due to pathological anatomical characteristics, Total parotidectomy is associated with a frequency of less than 0.4%.
Although it is classified as a benign tumor, multiple polyps have the potential to grow to high levels and may undergo malignancy, a risk that increases over time (9.5% chance of becoming malignant tumor in 15 years)
