The principle of salivary gland stone treatment is to remove the stone, eliminate the blocking factors and try to preserve the gland, which can be treated by conservative or surgical way: 1. Conservative treatment: for patients with small salivary stones, oral cotton balls dipped in citric acid or vitamin C tablets, or eating acidic fruits to promote salivary secretion, the stones may be discharged by themselves. 2. Surgical treatment: without recurrent infection, the gland is not fibrosis can be used for stone extraction, including incision lithotripsy, salivary gland endoscopy lithotripsy and salivary gland endoscopy-assisted incision lithotripsy. Salivary gland endoscopy is a minimally invasive surgical procedure. Large stones that cannot be removed by salivary gland endoscopy can be removed by lithotripsy, such as salivary gland endoscopic intraductal laser lithotripsy, electric lithotripsy, and pneumatic lithotripsy. When none of the above methods can remove salivary gland stones, recurrent infections occur, the gland atrophies and has lost its ingestive and secretory functions, then the lesion should be removed and glandular resection can be performed.
