Purpose of the study. To study the accuracy of intraoperative visualization and salivary calculus localization using augmented reality technology in comparison with ultrasound examination.
Material and methods. The retrospective data of eight patients who underwent surgical intervention in the volume of removal of a calculus from the parotid salivary gland via external access under general anesthesia with the visualization technique of ultrasound examination only were taken. Prospectively, 9 patients diagnosed with parotid salivary gland sialolithiasis were operated on by applying augmented reality technology. Results. In the main group of patients, the range of hologram misalignment varied from 570.00 to 1220.00 μm, the median misalignment was 1000.00 μm [595.00–1140.00], which was significantly less than that in the control group of patients who had ultrasound imaging only (p=0.0216). When analyzing the timing of surgery, we found that when augmented reality was used, the duration of surgical intervention ranged from 32.00 to 60.00 minutes, the mean duration being 44.11+8.30 minutes (95% CI: 37.73–50.49), which was significantly shorter than that with ultrasound imaging alone (p=0.0014).
Conclusion. This study of the augmented reality technology application during calculus removal provides a promising direction for clinical investigation and implementation of this technique in practice.
