Swollen salivary glandSalivary gland is one of the glands in the mouth that release saliva. There are about three major salivary glands, i.e. the parotid, submandibular, and sublingual glands. Each of these glands is balanced; there is one parotid gland on each side of the head, etc. The parotid glands are situated in front of the ears; the submandibular glands are under the mandible i.e. the lower jaw; and the sublingual glands are under the tongue. Most of the mucosal surfaces
within the mouth also hold many minor mucus-secreting salivary glands. Abnormal sublingual and submandibular glands can be felt when the floor of the mouth is palpated bimanually i.e. with two hands. Enlargement of the parotid gland can take place in front of the ear or overlying the mandible.
More of the swelling of salivary gland
The salivary glands can be exaggerated in various diseases. For example, in Sjogrens syndrome the salivary glands are infiltrated with lymphocytes and the salivary gland ducts are spoiled. The glands atrophy so there is less saliva, ensuing in extreme dryness of the mouth and lips that inhibits chewing and swallowing and promotes tooth decay and formation of the calculi in the salivary ducts. In mumps, there is characteristically painful swelling of the salivary glands, most commonly the parotid glands. The mumps virus enters by the mouth and may be found in saliva for days before the salivary glands swell and for the duration of glandular enlargement. Pain on chewing or swallowing, particularly acidic liquids such as lemon juice, is the earliest symptom of parotid gland involvement.
Conclusion
The parotid and any other swollen salivary glands are typically very tender. There is generally marked swelling over both parotid glands giving the well-known chipmunk appearance. Tumors can arise in the salivary glands; most normally occur in the parotid glands followed by the submandibular and minor glands and, least frequently, sublingual glands. About three-quarters of salivary tumors are benign slow-growing tumors. They are naturally painless nodules beneath normal skin or the mucosal lining of the mouth. The most familiar is the mixed salivary gland tumor. It occurs predominantly in women over 40. Malignancies can happen within such tumors, resulting in carcinoma.
