Cone beam CT sialography of Stafne bone cavity

B Li et al. Dentomaxillofac Radiol. 2011 Dec.

Abstract

Stafne bone cavity (SBC) was mostly described as a small oval radiolucency in the posterior mandibular region. To the best of our knowledge, the literature does not contain any report of the use of cone beam CT (CBCT) sialography for the diagnosis of this entity. The aim of this paper is to present a large, irregular and expanded atypical SBC, which made diagnosis difficult. A CBCT sialography was performed to get a definite diagnosis of this rare entity.

Axial (a), coronal (b) and sagittal (c) sections of cone beam CT (CBCT) showing a large bone cavity with an irregular border. The inner tissue seemed to be continuous with the submandibular gland. The buccal cortex was expanded and perforated in three-dimensional volume rendering processing (d)

Conventional sialogram showing that some branch ducts arising superiorly from the hilum of the submandibular gland seemed to distribute in the cavity area
Figure 4
Figure 4
The cavity area was mostly occupied by contrast-filled submandibular gland tissue, and soft tissue of low attenuation was also clearly demonstrated between the cavity wall and gland (a–c). The three-dimensional processing of the cone beam CT (CBCT) sialography shows the spatial relationship of submandibular gland and the bone cavity (d)
