Interventional Sialography and Minimally Invasive Techniques in Benign Salivary Gland Obstruction

Salivary gland obstruction is the commonest complaint affecting this organ and is usually due to the development of salivary calculi, ductal strictures, or both. Imaging has a role in the diagnosis of the cause, extent, and effects of obstruction. In recent years, the role of radiology has evolved; techniques, such as salivary stone lithotripsy, and salivary stone extraction and balloon ductoplasty are carried out under imaging guidance. This article reviews the current status of minimally invasive salivary interventions.
