Additional considerations:

As per Barsky and Silberman (1932)

a. "Movements of the cheek affect the duct, straightening its course or making it more irregular"

b. "A colored solution of some kind, such as 3.5 per cent iodine, is applied to the papilla, and the opening of the duct is disclosed"

Historical Perspective - perhaps identifying why some still consider the process of sialography to be 'invasive' (we do not consider it 'invasive'):

a. Use of cut-down for submandibular duct with identification of lingual nerve and mobilization of the duct for cannulation (Friedlander 1976)

b. Use of a series of horse-hairs to place (~4) to dilate the duct (mention also made of 4-0 nylon)
