It occurred to us that it might be of value in determining the anatomic status of the ducts, both large and small, of the parotid gland. In the case reported here treatment was at that time being carried out in this clinic, and iodized oil was injected. Later, a patient who was under study for another condition was given an injection of iodized oil in the right parotid duct.
Some time afterward, it was brought to our attention that in 1926 Carlsten2 in Germany had described a case of bilateral dilatation of Stenson's ducts in which he used iodized oil as an opaque medium. He injected the oil by means of a ureteral catheter and
