This study aimed to assess the value of cone beam computed tomography (CBCT) in the detection of salivary stones in patients with signs and symptoms of salivary gland obstruction. A total of 142 major salivary glands were analysed in a cohort of 127 patients with signs and symptoms of salivary gland obstruction. CBCT scans were performed in order to determine the presence of one or more salivary stones. All glands were also investigated by sialendoscopy. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated for the submandibular gland, the parotid gland, and the whole group, based on the observers' abilities to diagnose the presence or absence of calculi in the CBCT scan using the sialendoscopy data as the gold standard. Fifty salivary stones were detected in the CBCT scans of the 142 glands analysed: 34 in the submandibular gland and 16 in the parotid gland. The sensitivity (94%), specificity (90%), positive predictive value (84%), and negative predictive value (97%) for the whole group were good to excellent, with an overall accuracy of 92%. CBCT appears to be an ideal first-line imaging modality for patients with signs and symptoms of obstructed major salivary glands.
本研究旨在评估锥形束计算机断层扫描（CBCT）在检测有唾液腺梗阻体征和症状患者唾液腺结石中的价值。在一组127例有唾液腺梗阻体征和症状的患者中，共分析了142个主要唾液腺。进行CBCT扫描以确定是否存在一个或多个唾液腺结石。所有腺体还通过唾液腺内镜检查进行了研究。以唾液腺内镜检查数据作为金标准，根据观察者在CBCT扫描中诊断结石存在与否的能力，计算了下颌下腺、腮腺及整个组的敏感性、特异性、阳性预测值、阴性预测值和准确性。在分析的142个腺体的CBCT扫描中检测到50个唾液腺结石：34个在下颌下腺，16个在腮腺。整个组的敏感性（94%）、特异性（90%）、阳性预测值（84%）和阴性预测值（97%）均良好至优秀，总体准确率为92%。对于有主要唾液腺梗阻体征和症状的患者，CBCT似乎是一种理想的一线成像方式。
