In a clinical case we report on the primary application of modern methods of visualization using augmented reality in the treatment of patients with sialolithiasis for the localization of salivary stone in the parenchyma of the parotid salivary gland. Impression was taken and individual splint with radiopaque marker and a cutout for a probe was made. The splint was used for spiral CT of the head and neck. In surgical intervention under endotracheal anesthesia with intubation through the nose, the splint was placed in the mouth with a tap and a surgeon visualized the projection of the stone on the skin using glasses. The method allows to visualize salivary stone at all stages of surgery, regardless of the type of access or hydrotreatment. However, this technique does not make it possible to estimate the depth of the stone, as well as if the salivary stone is not fixed in the duct there is a risk of changing its position. In this regard, the use of augmented reality has a promising direction and requires further research.
