The procedures of sialendoscopic sialolithectomy have been progressively developing for more than the last ten years. However, any procedures reported previously in the world, needed an incision of the papilla or duct wall of the salivary gland to insert the sialendoscope. Therefore, I developed three types of fine sialendoscope, which could be inserted into the duct without incision of the papilla or duct wall of the salivary gland. One is a sialendoscope of 1.1-mm outer-diameter(POLYDIAGNOST GmbH, Germany) with 6000-pixels optic fibers, and it has a working channel to insert an ultra fine basket forceps of 0.38-mm outer-diameter and an irrigation channel. Two is a sialendoscope of 1.2-mm outerdiameter(FiberTech Co., Ltd., Japan) with 1600-pixels optic fibers and a working channel. Three is a sialendoscope of 1.40-mm outer妖iameter (POLYDIAGNOST GmbH, Germany) with 3000-pixels optic fibers, and it has a working channel to insert a 1.9 Fr basket forceps (Boston Scientific Corporation, USA) or a 1.9 Fr probe of an electrohydraulic lithotripter AUTOLITH^[○!R] (Northgate Technologies Inc., Elgin, U.S.A.). Using these newly developed sialendoscope, I established a non-surgical endoscopic sialolithectomy system, and succeeded to remove the sialoliths of the submandibular gland safely and surely under the sialendoscopic observations with a minimal invasion.
