Summary
Lingular mandibular bony defects (LMBD) were identified on CT scans. Buccolingual CT views clearly show the characteristic lingual opening of these incidental defects.
Area of Science:
- Dentistry
- Radiology
- Anatomy
Background:
- Lingular mandibular bony defects (LMBD) are rare anatomical variations.
- Their appearance on CT imaging, particularly in the buccolingual plane, requires detailed characterization.
Purpose of the Study:
- To document the CT imaging appearance of lingular mandibular bony defects (LMBD).
- To specifically assess the utility of the buccolingual plane in visualizing LMBD.
Main Methods:
- Retrospective review of five patients with incidentally discovered LMBD during dental implant planning CT scans.
- Utilized specific software to reformat axial CT data into panoramic and cross-sectional (buccolingual) views of the mandible.
Main Results:
- Five cases of LMBD were identified, with one patient presenting with both anterior and posterior defects.
- LMBD were asymptomatic incidental findings.
- The characteristic lingual opening of the defect was clearly visualized on axial and buccolingual CT reformations, but not on panoramic views.
Conclusions:
- The buccolingual CT plane provides valuable visualization of LMBD.
- This study adds to the radiologic description of LMBD, emphasizing the importance of specific imaging planes.
