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.
