OBJECTIVE
The aim of the study was to determine the clinical efficacy of maxillofacial cone-beam computed tomography (CBCT) for the diagnosis of suspected mandibular fractures and to evaluate whether findings would lead to a change in treatment.
STUDY DESIGN
CBCT imaging was performed for 164 patients with suspected mandibular fractures (231 sites) but equivocal clinical and radiological findings (conventional radiography). Images were interpreted by oral and maxillofacial surgeons and treatment decisions based on pre and postimaging were compared. Linear regression analyses were performed.
RESULTS
For 63.2% of sites (n = 146) the suspected diagnosis was confirmed by CBCT (P < .0001; R(2) = 0.93). For 4.33% of sites (n = 10) no fracture was identified. Additional fractures were identified in 17.75% (n = 41) and additional infractures in 14.72% (n = 34). The treatment plan was altered for 9.52% of sites (n = 22).
CONCLUSIONS
CBCT imaging of suspected mandibular fractures resulted in a change in the treatment plan in 9.52%.
目的
本研究旨在确定颌面锥形束 CT（CBCT）在诊断疑似下颌骨骨折中的临床疗效，并评估其检查结果是否会改变治疗方案。
研究设计
对 164 例疑似下颌骨骨折（231 处）但临床和影像学表现不明确（常规 X 线检查）的患者行 CBCT 成像。由口腔颌面外科医生对图像进行解读，并对比基于成像前后的治疗决策。进行线性回归分析。
结果
63.2%（n = 146）的疑似诊断得到 CBCT 证实（P <.0001；R² = 0.93）。4.33%（n = 10）的部位未发现骨折。17.75%（n = 41）的部位发现了额外骨折，14.72%（n = 34）的部位发现了额外的骨裂。9.52%（n = 22）的部位改变了治疗方案。
结论
疑似下颌骨骨折的 CBCT 成像导致 9.52%的部位改变了治疗方案。
