Obstructive parotitis is mostly caused by local factors, and the main focus is on removing the cause of the disease, removing stones if there are any, injecting medication into the catheter, and also adopting surgical treatment. If there are salivary gland stones in obstructive parotitis, it is necessary to remove the salivary gland stones. If the catheter opening is narrow, a blunt probe can be inserted into the catheter to gradually expand the catheter opening, or the doctor can inject iodized oil, antibiotics and other medicines into the catheter to inhibit bacteria and antimicrobial. The parotid gland can also be massaged from back to front to promote the secretion of saliva. For severe lesions that do not respond to conventional treatment, surgical removal by lobectomy of the parotid gland needs to be considered, but is generally less commonly used in clinical practice. Obstructive parotitis should be treated as prescribed by the doctor.
