Sialendoscopic Pneumatic Lithotripsy for Salivary Calculi: A New Technique and a Long-term Clinical Experience

We report our results comprising a series of 34 cases of sialolithiasis that were approached sialendoscopically with conventional instruments (ie, basket and/or forceps) and for which stone removal was unsuccessful and so were thereafter treated with pneumatic lithotripsy. Intraductal pneumatic lithotripsy was able to fragment 30 of 34 (88%) salivary calculi in total. No major complications occurred. All 30 treated glands returned to normal function without any symptoms. We believe that the success of sialendoscopy is closely related to the success of salivary stone fragmentability.
