探讨Stafne骨腔（SBC）的疾病来源、临床特点、影像学诊断方式及治疗方案，以减少临床中对SBC的漏诊和误诊。

回顾性分析2018年2月至2022年10月青岛大学附属医院口腔颌面外科就诊的10例SBC病例的临床表现、影像学特点及治疗方案，采用随机数字表法选取同期拍摄CBCT的年龄相仿、位置相近、形态相似，并经病理确诊为下颌骨根尖囊肿的患者10例，采用SPSS 22.0统计软件进行统计分析，对SBC与下颌根尖囊肿在锥形束计算机体层摄影术（CBCT）中灰度值（HU值）的大小进行比较，结合文献分析、总结其可能的病因及临床诊疗思路。

根据临床表现及影像学检查结果，10例确诊为SBC的患者中，9例位于下颌骨体后部、1例位于下颌升支。10例患者均无疼痛、肿胀和生理功能异常等表现，遂未行治疗，密切随访。SBC与下颌根尖囊肿的HU值之间差异具有统计学意义[HU_SBC = -86（-113，-78），HU_根尖囊肿 = 19（-12，37），Z = -3.311，P<0.001]。

SBC是一种相对罕见的发生于下颌骨的骨腔，因其位置和影像学的特殊性，临床上应高度重视，并结合相应检查方式来减少误诊和漏诊的发生，其中CBCT中的HU值大小可作为一种辅助判别SBC的手段。

To investigate the origin, clinical characteristics, imaging diagnosis and treatment of Stafne bone cavity (SBC) in order to reduce the misdiagnosis and missed diagnosis of the SBC.

Retrospective analysis was made on the clinical manifestations, imaging characteristics and treatment plans of 10 cases of SBC treated in Oral and maxillofacial surgery of the Affiliated Hospital of Qingdao University from February 2018 to October 2022. A total of 10 patients with similar age, location and shape of SBC who had taken CBCT in the same period in the hospital and were confirmed as mandibular apical cysts by pathology were selected with the random number table method. Statistical analysis was done with SPSS 22.0 The HU values of SBC and mandibular apical cysts in cone-beam computed tomography (CBCT) were compared at a significance level of 0.05. Finally, combined with a literature search, we summarized the possible causes, clinical diagnosis and treatment plans.

According to the clinical manifestations and imaging results, nine of the 10 patients with Stafne bone cavity were located in the posterior part of the mandibular body, and one was located in the mandibular ramus. None of the 10 patients had pain, swelling, abnormal physiological function and other symptoms, so they did not receive treatment and were closely followed up. The difference of HU value between Stafne bone cavity and mandibular apical cyst was statistically significant [ (HU_SBC = -86 (-113, -78) , HU_{apical cyst} = 19 (-12, 37) , Z = -3.311, P<0.001].

Stafne bone cavity is a relatively rare bone cavity occurring in the mandible. Due to its location and imaging particularity, clinical attention should be paid to it, and the corresponding examination methods should be combined to reduce the occurrence of misdiagnosis and missed diagnosis. The HU value of CBCT can be used as an auxiliary means to identify Stafne bone cavity, which is worthy of clinical promotion.
