Summary
Bifid mandibular condyles (BMCs) are rare. This study reports a rare bilateral BMC case, confirmed with 3D CT, supporting the theory of secondary condyle origin from the mandibular neck.
Area of Science:
- Dentistry
- Radiology
- Anatomy
Background:
- Bifid mandibular condyles (BMCs) are uncommon developmental anomalies of the temporomandibular joint.
- Previous literature predominantly reports unilateral BMCs, typically diagnosed via panoramic radiography.
Observation:
- This case details a rare instance of bilateral BMCs.
- Initial diagnosis was made using panoramic radiography.
- Confirmation and detailed visualization were achieved with colour-enhanced three-dimensional computed tomography (3D CT).
Findings:
- The advanced imaging (3D CT) provided clear evidence of bilateral BMCs.
- The findings support the hypothesis that secondary condyles originate from the mandibular neck.
Implications:
- This case expands the understanding of BMC presentation, highlighting the possibility of bilateral occurrence.
- Advanced imaging techniques like 3D CT are crucial for accurate diagnosis and characterization of rare mandibular anomalies.
- Further research into the etiology and clinical significance of bilateral BMCs is warranted.
