Summary
Periosteal reaction (PR) patterns on CT scans are valuable for diagnosing jaw diseases. Combining PR patterns with cortical bone destruction aids in differentiating osteomyelitis from malignant tumors.
Area of Science:
- Radiology
- Oncology
- Oral and Maxillofacial Surgery
Background:
- Periosteal reaction (PR) is a radiographic sign observed in various jaw pathologies.
- Understanding the diagnostic significance of PR patterns is crucial for accurate disease classification.
Purpose of the Study:
- To investigate the diagnostic significance of periosteal reaction (PR) in diseases of the jaws.
- To correlate PR patterns with specific jaw pathologies including osteomyelitis, trauma, cysts, benign, and malignant tumors.
Main Methods:
- Computed tomography (CT) scans of 1142 patients with maxilla or mandible disease were analyzed.
- Periosteal reaction patterns (parallel, irregular, spicule, Codman's triangle) were categorized and correlated with disease types.
Main Results:
- Periosteal reaction was present in 70 patients, notably in 40% of osteomyelitis and 15% of malignant tumor cases.
- Osteomyelitis predominantly showed parallel PR (91%), while malignant tumors exhibited a spicule pattern (61%).
- Combining PR patterns with cortical bone destruction achieved 90% accuracy in classifying diseases into four categories.
Conclusions:
- The pattern of periosteal reaction on CT, when analyzed alongside cortical bone destruction, is a useful tool.
- This combined approach aids in differentiating between osteomyelitis and malignant tumors of the jaw.
