The parotid gland is the largest of the salivary glands, located on each side of the face just in front of and below the ears. It produces saliva, which aids in digestion, lubricates the mouth, and helps protect against infection. The gland drains saliva into the mouth through the parotid (Stensen’s) duct. Conditions affecting the parotid gland may include infections such as mumps or bacterial parotitis, salivary stones that block the duct, inflammatory disorders, or tumors that can be benign or malignant. Symptoms of parotid gland problems may include facial swelling near the jaw or ear, pain while chewing, dry mouth, or fever if infection is present. Because the facial nerve runs through the parotid gland, certain conditions may also affect facial movement.
