We assessed whether ultrasonography (US) can be used in combination with cone beam computed tomography (CBCT) to image intraosseous jaw lesions.
Using CBCT and US, we evaluated 123 lytic intraosseous jaw lesions diagnosed in 121 patients with guidance from the CBCT findings. The lesions were classified into two groups based on histopathological evaluation: (1) cysts and (2) tumors and tumor-like lesions. US and histopathological findings on the lesions of the two groups and their relationships with each other were also assessed. Results are reported as means ± standard errors, and p < 0.001 was accepted as indicating statistical significance.
In total, 123 lesions were evaluated; 74 (60.2%) were cysts and 49 (39.8%) were tumors or tumor-like lesions. The CBCT and US findings were compatible as far as dimensional measurements of the lesions in the three planes (p < 0.001). The US and histopathological findings on the content of the lesions correlated (p < 0.001).
CBCT provides useful information for diagnosing intraosseous jaw lesions. Because it offers no valid Hounsfield unit (HU) value, it does not differentiate between solid and cystic masses. Thus, US can be used with CBCT to image intraosseous jaw lesions caused by buccal cortical thinning or perforation.
US provides useful information about intraosseous jaw lesions and can be used with CBCT to image such lesions caused by buccal cortical thinning or perforation. Clinicians can take this information into consideration when evaluating intraosseous jaw pathology.
评估超声（US）是否可与锥形束 CT（CBCT）联合用于成像颌骨内骨病变。
我们使用 CBCT 和 US 评估了 121 例患者的 123 个溶骨性颌骨病变，这些病变的诊断依据是 CBCT 结果。根据组织病理学评估，将病变分为两组：（1）囊肿和（2）肿瘤和瘤样病变。还评估了两组病变的 US 和组织病理学发现及其相互关系。结果以平均值 ± 标准误差表示，p<0.001 表示具有统计学意义。
共评估了 123 个病变；74 个（60.2%）为囊肿，49 个（39.8%）为肿瘤或瘤样病变。CBCT 和 US 的发现与病变在三个平面上的尺寸测量结果一致（p<0.001）。病变内容物的 US 和组织病理学发现相关（p<0.001）。
CBCT 为诊断颌骨内病变提供了有用的信息。由于它不能提供有效的亨氏单位（HU）值，因此不能区分实性和囊性肿块。因此，US 可与 CBCT 联合用于成像因颊侧皮质变薄或穿孔引起的颌骨内病变。
US 提供了颌骨内病变的有用信息，并可与 CBCT 联合用于成像因颊侧皮质变薄或穿孔引起的此类病变。临床医生在评估颌骨内病理学时可以考虑这些信息。
