title: [Lithotripsy in the conservative treatment of salivary stones].
abstract: Otolaryngologists and generalists as well are commonly involved in the evaluation and management of salivary gland stones. Most patients present with a history of recurrent swelling and pain in the gland, associated with eating. Up to date conservative therapy was limited to the treatment of the acute sialadenitis, which may develop as a consequence of the obstruction and often recurs until the function of the salivary gland ceases. Surgical treatment depends on the location of the calculus. Distal stones can be removed trans-orally by dilatation or incision of the duct, whereas those near the hilus and intraglandular stones required excision of the gland, including the disadvantage of a scar and the risk of injury to cranial nerves. Extracorporal shock wave lithotripsy is a new noninvasive method, which allows to destroy intra- and extraglandular salivary stones, mostly without the need of local or general anesthesia. Reported disintegration rates vary from 14% to 85%, depending on site and size of the calculus. About 80% of the patients remain symptomless Lithotripsy of salivary stones is a cost-effective, additional treatment modality to surgery and may be employed on an outpatient basis.
