3. Overview The salivary glands are exocrine glands that make, modify and secrete saliva into the oral cavity. They are divided into two main types: the major salivary glands, which include the parotid, submandibular and sublingual glands, and the minor salivary glands, which line the mucosa of the upper digestive tract and the overwhelming entirety of the mouth 

4. Frey's syndrome happens when you experience facial sweating and flushing when you eat. It's often a side effect of parotid gland surgery and happens due to nerve damage and abnormal nerve regrowth. Botox ® injections can help manage the sweating.

5. v A parotidectomy , also called parotid gland surgery, removes masses (benign or cancerous) in the parotid gland.

6. A mucocele is a benign, mucus-containing cystic lesion of the minor salivary gland. This type of lesion is most commonly referred to as mucocele . The more common is a mucus extravasation cyst; the other is a mucus retention cyst.

7. Sialadenitis Sialadenitis is inflammation of salivary glands, usually the major ones, the most common being the parotid gland, followed by submandibular and sublingual glands. It should not be confused with sialadenosis which is a non-inflammatory enlargement of the major salivary glands .

8. Sialolithiasis Salivary Stones ( Sialolithiasis ) “ Sialolithiasis ” is the medical term for salivary gland stones (calculi). These stones can cause pain and swelling of your salivary gland. Causes include dehydration, smoking and certain autoimmune diseases.

9. Sjogren syndrome is  a systemic autoimmune disorder commonly presenting with dryness involving the eyes and mouth due to inflammation and resultant pathology of the lacrimal and salivary glands . Dry mouth, also called xerostomia is  when the salivary glands in the mouth don't make enough saliva to keep the mouth wet. Dry mouth often is due to aging , systemic diseases (DM) the side effects of certain medicines or radiation therapy for cancer.
