title: Submandibular sialogram performed through a Wharton's duct fistula: technical adaptation of conventional technique.
abstract: We report a case of submandibular duct fistula in which a sialogram was performed through the fistulous opening after attempt of sialography through the Wharton's duct had failed. To our knowledge, this technical modification in obtaining a sialogram has not been described previously in scientific literature. Blunt-tipped needles and polythene catheters are commonly used for cannulation of the submandibular duct orifice for obtaining a sialogram. However, in this case, a larger gauge metallic cannula was employed to opacify the ductal system through the fistula.
