A member asked:

How accurate is a sialogram on finding a tumor in parotid gland .ent says no mass .he thinks just plugged duct.i am nervous about this test coming ?

A doctor has provided 1 answer

Not accurate: The presence of a mass in the parotid gland is suggestive of tumor. About 30% are malignant and on this basis the finding of a mass suggests need for parotidectomy. In actuality the operation is defining facial nerve and lifting gland off nerve so as not to damage it. Associated nodes frequently confirms Ca. A sialogram defines the presence of calculi in the duct system which may block drainage
