Cone beam computed sialography of sialoliths.

Cone beam CT is an emerging imaging modality used in maxillofacial imaging. This paper describes the use of cone beam sialography in two patients with salivary gland obstruction. In both cases, the obstruction was identified. The dose is comparable with conventional fluoroscopic techniques and has the advantage that the data may be viewed in a series of fine slices and in three dimensions, which may help in diagnosis and further management of the patient.
