Salivary stones

Salivary stones in the ducts from the parotid and submandibular glands can cause recurring symptoms such as swelling, pain, and infections.

Patients with recurring symptoms are suitable for endoscopic treatment.

Endoscopic technique (sialoscopy) is a good alternative to open surgery

Work-up consists of a CAT scan examination, possibly ultrasound, and in difficult cases MR sialography.

After dilatation of the duct, a sialoscope is used to inspect the duct and stones with a diameter up to about 3 mm can be extracted via a wire basket. If the stones are between 3 and 8 mm, they can be fragmented with a holmium-YAG laser.

Stenosis of the ducts sometimes needs to be dilated before the stone becomes accessible.

Sialoscopy can be carried out under local anesthesia, but if a laser is used the treatment must be carried out under general anesthesia due to pain.
