Abstract

Stafne mandibular bone cavity (SMBC) is an asymptomatic radiolucent lesion observed in the mandible on X-ray images, with well-defined borders. This lesion does not require treatment, and size changes are very rare. The purpose of this article is to summarize the radiological and clinical features of SMBC, aiming to prevent misinterpretation of this benign lesion as other pathologies and aid in differential diagnosis within the field of dental practice. A total of 32 patients who visited our hospital and were radiologically diagnosed with SMBC based on cone-beam computed tomography (CBCT) and panoramic images between 2005 and 2021 were included in this study. Among them, surgical intervention was performed in one case. Gender and age distribution of the patients, radiographic location and size of the lesion, relationship with the mandibular canal in CBCT, presence of cortical bone erosion in the mandibular lingual area in panoramic images, and the amount of residual cortical bone on the affected side in CBCT were investigated. Patients were 26 men (81.3%) and 6 women, with a mean age of 54.3 years. The average horizontal and vertical length was 16.6 mm and 10.6 mm. Out of a total of 32 cases, 29 cases were found in the posterior region of the mandibular body, while 3 cases were in the angle of the mandible. Lesions located below the mandibular canal were observed in 29 cases, while lesions involving the mandibular canal were present in 3 cases. Erosion of the mandibular lingual cortical bone was observed in 11 cases (34.4%), while 21 cases (65.6%) showed no erosion on panoramic images. Among the total of 14 cases (43.8%) where the cortical bone on the affected side was invaded, the average residual cortical bone thickness was 1.1 mm. SMBC is a benign lesion primarily found in the mandibular angle and posterior body of the mandible. In most cases, treatment is not necessary, and differentiation from other lesions can be achieved by understanding its clinical characteristics and features on panoramic radiographs and CBCT.

全景图像和锥形束计算机断层扫描中斯塔夫内下颌骨骨腔的放射学特征
下颌骨骨腔(Stafne mandibular bone cavity,SMBC)是一种在 X 射线图像上观察到的无症状放射状病变,边界清晰。这种病变不需要治疗,其大小变化也非常罕见。本文旨在总结 SMBC 的放射学和临床特征,以防止将这种良性病变误诊为其他病变,并帮助牙科临床进行鉴别诊断。本研究共纳入了 2005 年至 2021 年期间到我院就诊并根据锥束计算机断层扫描(CBCT)和全景图像被放射学诊断为 SMBC 的 32 例患者。其中一例患者接受了手术治疗。研究调查了患者的性别和年龄分布、病变的影像学位置和大小、CBCT 与下颌管的关系、全景图像中下颌舌侧皮质骨侵蚀的情况以及 CBCT 中患侧皮质骨的残留量。患者中有 26 名男性(81.3%)和 6 名女性,平均年龄为 54.3 岁。横向和纵向平均长度分别为 16.6 毫米和 10.6 毫米。在32例病例中,29例位于下颌骨体后部,3例位于下颌角。29例病变位于下颌骨管下方,3例病变涉及下颌骨管。11 例(34.4%)观察到下颌骨舌侧皮质骨侵蚀,21 例(65.6%)在全景图像上未显示侵蚀。在总共 14 例(43.8%)患侧皮质骨被侵蚀的病例中,平均残余皮质骨厚度为 1.1 毫米。SMBC是一种良性病变,主要发生在下颌角和下颌体后部。在大多数情况下,无需进行治疗,只要了解其临床特点以及全景X光片和CBCT的特征,就可以将其与其他病变区分开来。
