Salivary stones
How is it removed?
Your GPmay attempt to free up the stone by probing your salivary duct with a thin, blunt instrument.
If this doesn't work, you may need a procedure called a therapeutic sialendoscopy (mentioned above). A local anaesthetic is given to numb the mouth, and a very thin endoscope is pushed into the duct. If a stone is seen, a tiny instrument at the end of the tube is used to grab the stone and pull it out.
If the stone is large, it may need to be broken up first, using shock wave treatment (where ultrasound waves are directed at the stone to break it up). This is called extracorporeal shock wave lithotripsy.
In the past, doctors would remove salivary stones by making a small incision in the mouth, but such an operation is rarely necessary nowadays.
