AN IMPROVED technique of submandibular sialoangiography is presented. This method gives a more complete visualization of the submandibular gland duct system, allowing better evaluation of pathologic conditions of the gland. Although parotid sialoangiography is widely used, and results are commonly reported, survey of the literature reveals a paucity of reports describing results or methods of submandibular sialoangiography. True lateral, oblique, and postero-anterior views give excellent visualization of the duct system of the parotid gland. The only widely used views suitable for submandibular gland visualization1 include true lateral (Fig 1), oblique, and occlusal views, which give only partial visualization of the submandibular gland.
An axial projection utilizing the Hirtz2 and Bowen-Hirtz2,3 views (Fig 2), produces a unique view of the entire area of the submandibular gland and duct system free from superposition of osseous structure.4 Use of this view, prior to injection of contrast media, allows visualization of
