K11.6: Mucocele of salivary gland

Saliva or mucous has accumulated in one or more of your salivary glands.

The salivary glands produce saliva and transport it to the mouth. In all, there are 6 large salivary glands. The two parotid glands are located in front of the left and right ear. The two submandibular glands are located to the left and right at the back of the lower jaw. The two sublingual glands are located to the left and right beneath the tongue.

Saliva or mucous can accumulate in the salivary glands. If the saliva is unable to flow away properly, cavities with accumulated saliva can form. After an inflammation or injury, too, saliva may flow into the surrounding tissue. The accumulated saliva or mucous can cause a swelling to be noticed.
