Frey's syndrome (also known as Baillarger's syndrome, Dupuy's syndrome, auriculotemporal syndrome, [1] or Frey-Baillarger syndrome) is a rare neurological disorder resulting from damage to or near the parotid glands responsible for making saliva, and from damage to the auriculotemporal nerve often from surgery.
The most common salivary gland infection is mumps. It is characterised by bilateral swelling of the parotid glands; however, other major salivary glands may also be affected in around 10% of cases. The swelling persists for about a week, along with low-grade fever and general malaise.
Mucous extravasation phenomenon is a swelling of connective tissue consisting of a collection of fluid called mucus. This occurs because of a ruptured salivary gland duct usually caused by local trauma (damage) in the case of mucous extravasation phenomenon and an obstructed or ruptured salivary duct in the case of a mucus retention cyst. The ...
Sialolithiasis refers to the formation of calculi within a salivary gland. If a calculus forms in the duct that drains the saliva from a salivary gland into the mouth, then saliva will be trapped in the gland. This may cause painful swelling and inflammation of the gland. Inflammation of a salivary gland is termed sialadenitis. Inflammation ...
Parotitis presents as swelling at the angle of the jaw. Bacterial parotitis presents as a unilateral swelling, where the gland is swollen and tender and usually produces pus at the Stensen's duct. This pus is usually sampled and the bacteria within are identified. Common causative bacteria are Staphylococcus aureus, Streptococcus pyogenes and E ...
Then, when salivary secretion is stimulated, the mucus plug becomes stuck in the stricture. [1] The backlog of saliva behind the blockage causes the swelling, and the increased pressure inside the gland causes the pain. When the mucus plug is dislodged, the built up saliva is released and the swelling subsides.
Salivary-gland dysfunction occurs when salivary rates are reduced; this can cause xerostomia (dry mouth). [4] Some disorders affecting the salivary glands are listed below. Some are more common than others, and they are considered according to a surgical sieve; but this list is not exhaustive.
Conditions that can cause saliva overproduction include: [4] Rabies; Pellagra (niacin or vitamin B 3 deficiency) [6]; Gastroesophageal reflux disease, in such cases specifically called a water brash (a loosely defined lay term), and is characterized by a sour fluid or almost tasteless saliva in the mouth [7]
