Sialometry
Pronunciation: sy-uh-LOM-eh-tree
The clinical measurement of salivary flow rate, used to objectively assess salivary gland function.
Full Definition
Sialometry is the diagnostic procedure by which saliva volume over a timed period is collected and measured, either as unstimulated whole saliva (UWS) or stimulated whole saliva (SWS). It provides the objective data needed to confirm or exclude hyposalivation. Editors working on manuscripts in salivary gland disease, Sjögren's syndrome, or radiation oncology will frequently encounter this term. The procedure must be distinguished from sialography, which is an imaging technique. Editors should verify that authors specify whether measurements are unstimulated or stimulated, as normal values differ substantially between these two methods.
Usage
Usage note: Do not confuse with sialography (contrast imaging of salivary ducts) or sialendoscopy (endoscopic duct examination). Confirm whether measured flow is unstimulated or stimulated.
