Stafne's Bone Defect Correlated with Submandibular Glands: A Case Report and CBCT and MRI Analysis

Area of Science:

• Dentistry
• Oral and Maxillofacial Radiology
• Anatomic Pathology

Background:

• Stafne bone defect is a rare, benign developmental anomaly affecting the mandible's lingual aspect.
• Its exact etiology remains unclear, with theories suggesting glandular or ischemic origins.
• Typically discovered incidentally via panoramic radiography during routine dental examinations.

Observation:

• A case report details a Stafne bone defect in a 60-year-old male.
• Radiographic findings included a well-defined radiolucency below the mandibular canal.
• Cone beam computed tomography and MRI provided detailed localization and soft tissue identification.

Findings:

• The lesion was characterized as a depression of the lingual cortical plate.
• Histological analysis confirmed the defect was filled with submandibular gland tissue.
• Differential diagnosis considered various cystic and bone lesions.

Implications:

• Highlights the importance of advanced imaging (CBCT, MRI) for accurate diagnosis of Stafne bone defects.
• Contributes to understanding the potential involvement of salivary gland tissue in mandibular bone anomalies.
• Emphasizes the benign nature and incidental discovery of this condition in dental practice.
