Our study aimed to determine the prevalence and volumetric estimates of Stafne bone cavities (SBC) on cone beam computed tomography (CBCT) images.
This retrospective study, which involved the CBCT images of 1141 men and 1260 women with an age range of 10-90 years, aimed to determine the prevalence of SBCs and to calculate their volumes using the semi-automatic segmentation method.
A total of 15 SBCs were diagnosed in 14 patients. Among the detected SBCs, 7.14% were found in a female patient and 92.86% were found in 13 male patients. Of the total number of SBCs, 6.67% were anteriorly located and 93.33% were posteriorly located. Bilateral SBCs had a prevalence of 0.04%; unilateral posterior SBCs 0.54% and anterior SBCs 0.04%. The mean SBC volume was calculated as 338.05 mm.
The results of our study showed that SBC is a rare anomaly. In contrast to two-dimensional imaging techniques, CBCT allows a precise determination of SBCs' pattern of impact on adjacent bony structures, relationship with the mandibular canal and dimensions.
本研究旨在通过锥形束 CT（CBCT）图像确定 Stafne 骨腔（SBC）的发生率和容积估算。
这是一项回顾性研究，共纳入了 1141 名男性和 1260 名年龄在 10-90 岁之间的女性的 CBCT 图像，旨在确定 SBC 的发生率，并使用半自动分割方法计算其容积。
在 14 名患者中诊断出 15 个 SBC。在检测到的 SBC 中，7.14%位于女性患者，92.86%位于 13 名男性患者。在总共的 SBC 中，6.67%位于前侧，93.33%位于后侧。双侧 SBC 的发生率为 0.04%；单侧后侧 SBC 为 0.54%，前侧 SBC 为 0.04%。SBC 的平均体积计算为 338.05mm。
本研究结果表明 SBC 是一种罕见的异常。与二维成像技术相比，CBCT 可以精确确定 SBC 对相邻骨结构的影响模式、与下颌管的关系和尺寸。
