Sialography has gained in importance as a method of diagnosis of the diseases of the salivary glands of late years. In the basic studies of sialography, one of the most important problems involves the amount of contrast medium (moljodol) to be injected. The amount to be injected is determined based on several criteria that have been established for the purpose of.obtaining unvarying sialograms for each case at all times.
Reviewing the criteria established for injection of moljodol, the author evolved the method of determining the amount based on intraductal pressure. A device for measuring intraductal pressure was perfected, and experiments were carried out in animals and humans to study the intraductal pressure with varying amounts of moljodol in the ductal system. In animals, injections were done by three different methods, with intraductal pressure being measured in each case. The relation between intraductal pressure and the amount of moljodol injected was clarified and the validity of the criteria based on intraductal pressure was proved by comparing the results with cinesialographic and sialographic findings, as well as with the specimens of the salivary glands injected with acrylic resin and histologic specimens of the glands stained with Sudan III. After injection of moljodol, patients were followed with X-rays to see how long it will take for injected moljodol to be withdrawn entirely.
