Cysts of Salivary Glands

By Dr. Vishaal Bhat on Sunday 2 December 2007 with 0 comments



Retention cysts of salivary glands originate from widening of a duct either inside a gland or outside of it. The cause may be a post-inflammatory or after-injury stricture that gradually closes a gland’s duct. Saliva accumulates before a barrier and widens the duct by pressure (ductocele). Among retention cysts of the sublingual salivary gland, there is ranula, a cyst that appears on the floor of the mouth on the side of the tongue frenulum. It can grow into a size that obstructs the tongue’s movements. In some cases it may break open and get emptied spontaneously. This cyst often reappears if it was not removed surgically.

Retention cysts of small mucinous glands (mucocele) appear on the mucosa of the lower lip, cheeks, palate or tongue. These cysts on the lower lip of children can be traumatized by biting, causing them to break open. If even a small amount of mucinous saliva penetrates the lower lip tissue, a painful inflammation occurs - mucophagous granuloma.

Cystic widening of the parotid gland Stenon’s duct or Wharton’s duct of the submandibular gland appear scarcely, called ductocele and sialodochocele, respectively. It is presumed that these cysts are caused by an inborn atony of a salivary gland duct’s wall followed by dilatation. A causative factors include increased pressure inside the mouth of musicians playing brass instruments, or glass blowers.
