Q38: Other congenital malformations of tongue, mouth and pharynx

Q38.4: Congenital malformations of salivary glands and ducts

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. The salivary glands guide the saliva to the mouth via certain ducts.

While developing in the womb, many different types of tissue develop in the body. The organs and body parts develop out of the various types of tissue. If tissue fails to develop properly, defects can occur. One or more salivary glands or salivary gland ducts can be affected by this type of defect.
