Salivary Gland Abnormalities and Diagnostic Procedures

_________________________________________

Ptyalism (PTY):

Excessive flow of saliva; also called hypersalivation

Sublingual sialocele (SG/MUC/S):

Mucus extravasation phenomenon manifesting in the sublingual region; also called ranula

Pharyngeal sialocele (SG/MUC/P):

Mucus extravasation phenomenon manifesting in the pharyngeal region

Cervical sialocele (SG/MUC/C):

Mucus extravasation phenomenon manifesting in the intermandibular or cervical region

Mucus retention cyst (SG/RC):

Intraductal mucus accumulation with duct dilation resulting from obstruction of salivary flow (e.g., due to a sialolith)

Sialadenitis (SG/IN):

Inflammation of a salivary gland.

Sialadenosis (SG/ADS):

Non-inflammatory, non-neoplastic enlargement of a salivary gland; also called sialosis

Necrotizing sialometaplasia (SG/NEC):

Squamous metaplasia of the salivary gland ducts and lobules with ischemic necrosis of the salivary gland lobules; also called salivary gland infarction

Salivary gland adencarcinoma (SG/ADC):

Adenocarcinoma arising from salivary glandular or ductal tissue; use abbreviations under

OM

for other salivary gland tumors.

Sialocele (or salivary mucocele):

Clinical term indicating a swelling that contains saliva and including mucus extravasation phenomenon and mucus retention cyst

Mucus extravasation phenomenon:

Accumulation of saliva that leaked from a salivary duct into subcutaneous or submucosal tissue and consequent tissue reaction to saliva

Sialolithiasis (SG/SI):

Condition characterized by the presence of one or more sialoliths, a calcareous concretion or calculus (stone) in the salivary duct or gland

Sialography (RAD/SG):

Radiographic technique where a radiopaque contrast agent is infused into the ductal system of a salivary gland before imaging is performed.

Salivary gland resection (SG/X):

Surgical removal of a salivary gland

Marsupialization (MAR):

Exteriorization of an enclosed cavity by resecting a portion of the cutaneous or mucosal wall and suturing the cut edges of the remaining wall to adjacent edges of the skin or mucosa, thereby creating a pouch; use

SG/MAR

for marsupialization of a sublingual or pharyngeal sialocele.
