Buccal bifurcation cyst (BBC) is an uncommon inflammatory odontogenic cyst that generally occurs at the buccal region of the permanent mandibular first molars in children aged 6-8 years. The diagnosis of BBC cannot be made from the histopathologic features; therefore, diagnosis is primarily based on specific clinical and radiographic findings. In this case report, we present the clinical and radiological findings, including ultrasonography (USG) and cone-beam computed tomography (CBCT) images, of a 10-year-old boy who was referred with a complaint of swelling on the lower right jaw. According to the radiographic and clinical findings, the differential diagnosis of this lesion included lateral radicular cyst, lateral periodontal cyst, dentigerous cyst, eruption cyst, and others. Recently, in addition to classical radiographies and CBCT, USG has been considered important for diagnosis. In particular, if a cyst produces a perforation in the cortical bone, it is helpful to make a pre-diagnosis with USG.
颊部分叉囊肿（BBC）是一种不常见的炎症性牙源性囊肿，通常发生在 6-8 岁儿童的下颌恒磨牙颊侧。BBC 的诊断不能仅依据组织病理学特征，因此主要基于特定的临床和影像学表现。本病例报告介绍了一名 10 岁男孩的临床和影像学表现，包括超声（USG）和锥形束计算机断层扫描（CBCT）图像，该男孩因右下颚肿胀就诊。根据影像学和临床发现，该病变的鉴别诊断包括侧方根囊肿、侧方牙周囊肿、含牙囊肿、萌出囊肿等。最近，除了经典的射线摄影和 CBCT 外，USG 也被认为对诊断很重要。特别是如果囊肿在皮质骨上产生穿孔，USG 有助于进行初步诊断。
