Two huge maxillofacial osteoma cases evaluated by computed tomography

Area of Science:

• Oral and Maxillofacial Surgery
• Otolaryngology
• Radiology

Background:

• Osteomas are benign osteogenic neoplasms or hamartomas.
• They are the most common mesenchymal neoplasms of the paranasal sinuses and frequently occur in the mandible.
• Osteomas typically affect individuals over 40 years old.

Observation:

• While often small, some osteomas can grow large, causing significant damage, particularly in the frontoethmoid region.
• Compact bone osteomas are uniformly radiopaque, while those with cancellous bone show internal trabecular structure.
• Computed tomography (CT) is superior to conventional radiography for assessing the extension and internal structure of osteomas.

Findings:

• This discussion covers clinical and imaging features of two osteomas: one in the ethmoid sinus and another in the mandible.
• Key differential diagnoses and pathological features are also addressed.
• The imaging characteristics of osteomas, including their composition and internal structure, are detailed.

Implications:

• Accurate imaging is crucial for understanding the full extent of osteomas.
• Distinguishing osteomas from other lesions is vital for appropriate patient management.
• This case series highlights the utility of CT in diagnosing and characterizing osteomas in the paranasal sinuses and jaws.
