Parotid stones are very rare in clinical practice because the parotid gland itself is a mostly plasma gland, which means that the saliva secreted by the parotid gland is relatively thin and has a relatively low chance of producing stones. If a parotid stone is found, the first thing to do is to look at the establishment of the hospital you are seeing. However, if the hospital has a separate department of stomatology, you can usually register with the Department of Oral and Maxillofacial Surgery for examination. If you are in a large comprehensive tertiary dental hospital, you can consider the Department of Imaging to perform parotid imaging to check the specific location of parotid stones, and then the Department of Imaging or the Department of Oral and Maxillofacial Surgery to remove the stones from the parotid gland.
