Sialendoscopy (SE) represents nowadays one of the standard diagnostic and therapeutic procedures in the treatment of major salivary glands lithiasis. We know from experience that it is successful only in small percentage of patients, when used in monotherapy. However, it represents an indispensable part of all of the combined minimally invasive gland-preserving treatment techniques, the success rate of which is around 90%. In this work, we focused on the role of sialendoscopy in the treatment of patients with larger inflamed fixed stones in glandula parotis. We conducted a total of 364 sialendoscopy procedures in 332 patients on our site. We have confirmed lithiasis as a cause of salivary gland obstruction in 246 (74%) patients. In 9 patients there was larger, single, or multiple inflamed fixed lithiasis of glandula parotis. In this subgroup of patients endoscopically assisted sialolithectomy from external mini-incision has become the method of choice. In 9 of the 9 (100%) cases we have achieved complete elimination of stones, and in 8 of the 9 (89%) cases we have achieved complete elimination of complaints. Sialoendoscopically assisted sialolithectomy of glandula parotis from external mini-incision has proved to be highly effective technique to eliminate stones with minimal complications.
