Sialography

Sialography is a well established procedure for examination of the salivary glands and was introduced in the middle 1920's independently by BARSONY ( 1925 ), U SLENGHI, and CARLSTEN (1926). All used oily contrast media. As early as 1913, however, ARCELIN had injected bismuth emulsion into Wharton's duct prior to radiography for a calculus. Previous reports concerning the technique of sialography mainly dealt with the choice between different kinds of contrast media and the technique of filling the ductal systems. Only a few considerations of the proper projections appear in the literature (ROSE 1950, HETTLER & LAUTH 1961, GARUSI 1964, OLLERENSHAW & Ross 1950, 1956). The contrast medium used in sialography nowadays is almost always watersoluble, the oily suspensions previously used having been abandoned. This has led to a modification of the technique in so far as the injection can be performed through thin tubing introduced into the main duct of the gland to be examined (GULLMO & BOOK-HEDERSTROM 1958, LrvERuD 1959, DREVATTNE & STIRIS 1964, GARUSI 1964, HETTLER & LAUTH 1961, RUBIN et coll. 1955).
