[Stenosis and other non-sialolithiasis-related obstructions of the major salivary gland ducts. Modern treatment concepts].

The treatment of stenoses and non-stone-related obstructive diseases of the major salivary glands has undergone significant changes due to the development of minimally invasive treatment modalities. Correct diagnosis can often not be established in detail with all diagnostic tools except sialendoscopy, which is necessary for gland-preserving therapy. Over the last 10 years a range of minimally invasive treatment approaches aimed at preserving gland function have been developed. In addition to sialography-controlled therapy, interventional sialendoscopy plays a central role, representing the treatment of first choice in all stenoses and non-stone-related obstructions of the salivary duct system and with a success rate of about 85%-90%. By combining sialendoscopy with other minimally invasive surgical procedures, the function of the gland can be preserved in more than 95%. Thus sialendoscopy plays a crucial role in the treatment of non-stone-related obstructive diseases of the major salivary glands. In stenoses of the salivary gland ducts extirpation of the gland should be considered only as a last step.
