The treatment of sialolithiasis by sialolithotripsy

Aim. To study the effectiveness of treatment of sialolithiasis by sialolithotripsy. Methods. Between 2015 and 2018, extracorporeal shockwave lithotripsy of salivary stones of 39 patients was performed in the Nasreddin Tusi Memorial Clinic. The stone was located in the submandibular gland and its duct for 33 patients and the parotid salivary glands and its duct for 6 patients. The average age of patients was 50±3.38 (between 22 and 77). Results. Stone fragmentation as a result of sialolithotripsy was achieved in 36 (92.7%) of 39 examined patients (p=0.031). In 3 patients the stone was completely fragmented, but due to the narrow lumen of the main duct, it did not move away. In 3 patients with calculus size more than 2 cm, the stone was not fragmented. According to our results, the necessary effect was achieved in 85% of cases and was unachieved in only 15% of cases. Conclusion. Given the complexity of the surgical treatment in patients with salivary stone and potential postoperative complications, especially with the stone localization within the parotid gland, we concluded that extracorporeal shockwave lithotripsy is a promising alternative treatment for patients with salivary stone.
