Three sets of salivary glands exist in the head and neck region:

• in front of the ears (parotid)
• below the jaw (submandibular)
• underneath the tongue (sublingual)

Additionally, there are numerous very small salivary glands throughout the mouth and throat. Although tumors can arise in these areas, they are rare. Thus, any child with a growth in these areas should be seen by a head and neck surgeon.
