Generally, the treatment of sialolithiasis aims at removal of the salivary stone, either intraorally and extraorally. It is thought that many cases of sialolithiasis can be cured by removing the salivary stone, except for some cases in which it is necessary to remove the salivary gland. The authors therefore devised a nonsurgical method by which a salivary stone could be removed safely and with certainty using endoscopy, and applied it clinically. So far 39 cases have been treated by this method and in 33 (84.6%) only the salivary stone has been successfully removed. With regard to extirpation of the salivary stone, this method could be emoloyed regardless of the location of the stone and was effective with stones up to 5mm diameter. The success of this method was affected by the degree of adhesion between the salivary duct and the stone, occlusion of the salivary duct or severe damage to the submandibular gland. It was confirmed that this method is a safe nonsurgical method with a high extirpation rate and should be considered before attempting the usual surgical procedure.
