The value of cone beam computed tomography in the detection of salivary stones prior to sialendoscopy

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.
