Summary
Static bone cavities (SBCs) are not submandibular gland aberrations. Imaging reveals SBCs contain fatty tissue and blood vessels, not gland tissue, challenging previous assumptions.
Area of Science:
- Radiology
- Anatomy
- Oral Surgery
Background:
- Static bone cavities (SBCs) are anatomical findings often incidentally discovered on dental radiographs.
- Previous hypotheses suggested SBCs result from aberrations of the submandibular gland.
Purpose of the Study:
- To investigate the true contents of static bone cavities (SBCs) using advanced imaging techniques.
- To determine if SBCs are indeed related to submandibular gland aberrations.
Main Methods:
- Computed tomography (CT) and magnetic resonance imaging (MRI) were utilized to examine 12 subjects with SBCs.
- Both non-contrast-enhanced and contrast-enhanced CT scans were performed, with MRI on a subset of patients.
Main Results:
- No submandibular gland tissue was identified within the SBCs in any subject.
- Fatty tissue was consistently observed in all SBCs via CT.
- Blood vessels were detected in most SBCs (10/12), with some showing dilatation and tortuosity.
Conclusions:
- The study concludes that SBCs are not formed by submandibular gland aberrations.
- Imaging findings indicate SBCs primarily consist of fatty tissue and vascular structures.
- This redefines the understanding of SBCs, differentiating them from glandular anomalies.
