“…We recommend the patient undergo a computed tomography (CT) scan because this is the most efficient exam for the preoperative diagnosis of sialolithasis (100% sensitivity, 75% specificity, 99% positive predictive value, and 100% negative predictive value [10]). CBCT, which is interesting in terms of X-ray dose reduction and reduced metallic artefacts, can also be done, even if it provides less information regarding the soft tissues 10 . Multi-planar reconstructions allow the precise assessment of the topography of the lithiasis (extra-glandular, which is frequent, or intra-glandular, which is much rarer).…”
