Brief Answer:
Ranges from non-invasive to invasive

Detailed Answer:
Thanks for asking on HealthcareMagic.

I have gone through your query and understand your concerns. Submandibular salivary gland stones do not always need to be treated. The requirement of treatment depends on the complaints caused by it or the size of the stone (smaller stones tend to come out on their own). This calls for a clinical correlation. As such, shock wave therapy (Extracorporeal shock wave lithotripsy) is a good more of non-invasive treatment wherein the stone is crushed using shock waves and the smaller fragments come out normally. Laser fragmentation acts in the same way. There are other minimally invasive modalities like sialendoscopy wherein an endoscope is introduced, the stone localized, and then dissected and removed in an intraoral approach. The last option is an open surgery.

Let me know if you have further queries and I would be happy to assist.

Regards
