Definition and Overview of Stafne Defect
- Stafne Defect is a bone cavity near the angle of the mandible
- It is also known as Stafne Bone Cavity or Static Bone Cyst
- The defect is usually asymptomatic and doesn't require treatment
- The condition is more common in males than females
- Stafne Defect is often discovered incidentally during dental imaging

Etiology and Pathogenesis of Stafne Defect
- Stafne Defect is believed to be a developmental anomaly
- It occurs due to a lingual cortical bone concavity near the mandibular angle
- The defect is caused by the displacement of the submandibular salivary gland
- Heterotopic salivary gland tissue can be found within the defect
- Stafne Defect is not associated with trauma or infection

Diagnosis and Imaging of Stafne Defect
- Diagnosis is typically made through radiographic imaging
- Panoramic radiographs are commonly used to identify the bone cavity
- Computed tomography (CT) scans can provide detailed information about the defect
- Magnetic resonance imaging (MRI) may be used to assess the soft tissue components
- Differential diagnosis includes other radiolucent lesions of the mandible

Clinical Significance and Management of Stafne Defect
- Stafne Defect is usually asymptomatic and doesn't require treatment
- Surgical intervention is not necessary unless there are complications
- Monitoring the defect through regular imaging is recommended
- If the defect causes aesthetic concerns or functional issues, surgical repair may be considered
- The risk of pathological fractures associated with Stafne Defect is extremely low

Research and Literature on Stafne Defect
- Stafne Defect was first described by Edward C. Stafne in 1942
- Several studies have reported cases of Stafne Defect with different variations
- The prevalence of Stafne Defect ranges from 0.08% to 0.26% in various populations
- Research has explored the radiographic characteristics and variations of the defect
- The etiology and pathogenesis of Stafne Defect are still not fully understood
