目的：目的：探讨骨膜反应（PR）在颌骨疾病中的诊断意义。方法：对1142例上颌骨或下颌骨CT检查患者的PR发生率进行调查。PR的形态分为平行、不规则、毛刺或Codman三角形。我们研究了PR的模式的关系，骨髓炎，创伤，囊肿，良性肿瘤和恶性tumors.Results的特定疾病类别：70例患者被发现有PR。它被发现在40%的骨髓炎和15%的恶性肿瘤的情况下。唯一的良性病变是嗜酸性肉芽肿。没有囊肿。年轻患者、肉瘤或骨转移患者PR的发生率高于癌患者。91%的骨髓炎患者表现为平行于皮质骨的单层或多层PR，而61%的恶性肿瘤患者表现为骨针模式。除Codman三角外，PR模式均与任何一种疾病类别无关。PR型与皮质骨破坏型相结合，可将90%的PR患者正确地分为骨髓炎、创伤、良性病变和恶性肿瘤4种类型。结论：PR型与皮质骨破坏型相结合，对骨髓炎和恶性肿瘤的鉴别诊断有一定价值。
Objectives: To investigate the diagnostic significance of a periosteal reaction (PR) in diseases of the jaws.Methods: The frequency of PR was investigated in 1142 patients who had undergone CT of the maxilla or mandible. The pattern of PR was categorized as either parallel, irregular, spicule or Codman's triangle. We examined the relationship of the pattern of PR to the specific disease categories of osteomyelitis, trauma, cysts, benign tumours and malignant tumors.Results: Seventy patients were found to have PR. It was found in 40% of cases with osteomyelitis and 15% of malignant tumors. The only benign lesion was an eosinophilic granuloma. There were no cysts. The frequency of PR was higher in younger patient and in those with sarcomas or bone metastases compared with those with carcinomas. Ninety-one percent of the patients with osteomyelitis showed single or multi-layered PR parallel to the cortical bone, while 61% of those with malignant tumors had a spicule pattern. With the exception of Codman's triangle, none of the PR patterns were specifically associated with any one disease category. When the PR pattern was combined with the pattern of cortical bone destruction, 90% of the patients with PR could be correctly assigned to one or other of the four disease categories of osteomyelitis, trauma, benign lesion or malignant tumor.Conclusions: The pattern of PR on CT in combination with the pattern of the cortical destruction of the cortex is useful in differentiating osteomyelitis from malignant tumors.
