Pronounced cy-al-endoscopy, sialendoscopy is a new technique available for the minimally invasive treatment of diseases of the salivary gland. This technology is relatively new to the United States.

It is is a great tool to treat problems of the salivary glands and helps to avoid many open salivary gland operations.

Briefly, the technique involves the use of a small, very thin, semi-rigid scope, pictured below.

The scope is then placed into one of the major salivary gland ducts, located either under the tongue (submandibular gland) or in the cheek, next to the upper teeth (parotid gland).

Special instruments can then be inserted into the ducts, in order to either dilate areas of narrowing (stenosis) or to break up and remove stones (sialoliths).
