Summary
Stafne bone defects (SBD) are uncommon mandibular anomalies. Cone beam CT (CBCT) and multislice CT (MSCT) effectively detect SBDs, with CBCT offering lower radiation exposure.
Area of Science:
- Dentistry
- Oral and Maxillofacial Radiology
- Anatomic Pathology
Background:
- Stafne bone defect (SBD) is a rare developmental anomaly of the mandible.
- Its etiology is often attributed to pressure from adjacent soft tissues, commonly the submandibular gland.
Purpose of the Study:
- To determine the frequency of Stafne bone defects (SBD) in a Turkish population.
- To describe the clinical and radiological features of diagnosed SBD cases.
Main Methods:
- A retrospective analysis of 34,221 panoramic radiographs was conducted.
- Multislice CT (MSCT) and cone beam CT (CBCT) were used for diagnostic confirmation in select cases.
Main Results:
- Stafne bone defects (SBD) were identified in 29 out of 34,221 patients (0.08%).
- The majority of affected individuals were male (86.2%), with a mean age of 49.6 years.
- SBDs were predominantly located in the posterior mandible, with MSCT revealing glandular tissue within the defects.
Conclusions:
- Stafne bone defects (SBD) are infrequent mandibular anomalies.
- Findings support the theory of submandibular gland herniation causing SBD.
- Both CBCT and MSCT are suitable for SBD detection, with CBCT recommended for its lower radiation dose.
