Sialendoscopy (say "sy-uh-len-DAW-skuh-pee") is a procedure to diagnose and treat problems inside the salivary gland ducts. These are the tiny tubes that carry saliva into your mouth. Instead of making cuts on the outside of your face or neck, a doctor uses a very thin, flexible tube with a camera on the end. The tube is placed in the duct opening inside your mouth. Small tools can be placed in the ducts.
In many cases, your doctor can find the problem and treat it in the same visit.
