sialography
Pronunciation: sigh-ah-LOG-rah-fee
A radiographic imaging technique using contrast material to visualize the ductal system of salivary glands.
Full Definition
A specialized diagnostic imaging procedure used in oral and maxillofacial surgery to evaluate salivary gland disorders. Contrast material is injected through the natural ductal opening (Stensen's or Wharton's duct) to outline the ductal anatomy. This technique is particularly valuable for diagnosing ductal strictures, sialolithiasis, Sjögren's syndrome, and chronic inflammatory conditions. Modern variations include CT sialography and MR sialography, which provide cross-sectional imaging. The procedure helps guide treatment decisions between conservative management and surgical intervention for salivary gland pathology.
Usage
Usage note: Specify the imaging modality (conventional, CT, or MR sialography) in reports.
