Sialolithiasis is the most frequent cause of chronic obstruction of salivary glands and is responsible, according to various authors, for 60 – 80 % of all benign obstruction pathologies. Until very recently the resection intervention was the standard therapeutic procedure in cases of non palpable concrements. A technical progress in the nineties of the last century enabled endoscopy to be incorporated into these problems and made also dynamic development of mini invasive functional therapy possible. At the present time sialolithiasis, mini invasive surgery and ultrasonography navigated lithotripsy (ESWL) are the most frequently used methods in mini invasive therapy of sialolithiasis. Indications of the individual techniques are governed by a specific finding, but they partly overlap and can be combined.

In the present cohort the authors summarized their first experience with sialoendoscopy. The attention was particularly devoted to its role in diagnostics and therapy of sialolithiasis. In 160 patients with clinical manifestations of chronic obstruction disease of salivary gland in authors performed 1833 sialoendoscopy interventions from the half of 2009 to the half of the 2013 year. The study was retrospectively prospective. Sialolithiasis was established in 72% of the cases. The concrements found by endoscopy were removed by sialoendoscopy or mini invasive interventions or their combination. The cohort of specified by local anesthesiology only. In the concrements found distally of the gland hilus the size and distance from the orifice of the influenced only the type and complexity of the subsequently selected technique for removal, but it did not influence success of the elimination. In sizable concrements found in the hilus of submandibular salivary gland, where the size did not enable intraductal endoscopic manipulation, local anesthesia proved to limiting factor of successful intraoral sialectomy in our view and experience. In the proximal ramification of the gland parenchyma only the concrements smaller than 3 mm had real expectation of the intraductal removal. Sialoendoscopy as a monotherapy was successfully used only in a small number of patients. However, when combined with techniques of mini invasive therapy, the elimination of concrements proved to be complete in 61% of patients. In conditions of general anesthesia in the group of patients with sizable submandibular lithiasis of submandibular salivary gland the potential for mini invasive therapy in our group theoretically increased to 82%. In the case of ESWL availability a further increase in percentual success rate may be expected to occur in mini invasive therapy. The diagnostic contribution of sialoendoscopy became obvious is 21% of falsely negative ultrasonographic examinations. In our experience sialoendoscopy univocally confirmed its principal importance in mini invasive therapy of sialolithiasis. In order to reach a high success rate in the therapy of sialolithiasis, sialoendoscopy should be combined with other techniques and, is indicated cases, with general anesthesia.
