Minimally invasive techniques for the treatment of benign salivary gland obstruction.

This paper reviews the literature published on minimally invasive techniques developed to treat benign salivary gland obstruction. Techniques reported include extracorporeal and intracorporeal salivary gland lithotripsy, endoscopy and radiologically guided techniques for the extraction of calculi and dilatation of duct strictures. These techniques are described, their advantages and disadvantages discussed and their success rates compared. Recommendations are made on the most appropriate application of each technique.
