PATHOLOGY OF THE SALIVARY GLANDS - Obstructive Disorders

By Dr. Vishaal Bhat on Saturday 5 January 2008 with 0 comments



Mucocele

  • Most common of the obstructive disorders; results from trauma to minor salivary glands with extravasation and pooling of mucus in surrounding tissues

  • Seen mainly in young persons; the lips are the favoured site

  • Usually appear as small, fluctuant masses—large mucoceles of the floor of the mouth are known as ranulas; these may extend into the neck


Sialolithiasis

  • This is the formation of stones (calculi) in the ducts of salivary glands

  • The stones result from the calcification of an intraluminal nidus e.g. dried secretions or cellular debris—they are composed mainly of calcium phosphate

  • Inflammation of the salivary duct and stasis of saliva have been suggested as predisposing factors—the submandibular duct is the most common site

  • Peak incidence in the fourth and fifth decades

  • The stones vary in size, surface texture and colour

  • Recurrent infection of affected glands (secondary to obstruction) is common
