Introduction: Benign obstructive disease of salivary gland (SG) ducts is the most common SG disorder. Its diagnostics is based on the patient history and the results of clinical examination, ultrasound and sialendoscopy. The x-ray sialography is currently less commonly used procedure. The aim of the present study was to compare usefulness of sialendoscopy and sialography in the detection of benign salivary obstruction.

Methods: Patients with recurrent SG swelling were included in our study. As a first step, sialography was performed and patients were sorted out into three groups (sialolithiasis, duct stenosis, no pathology). Subsequently, sialendoscopy was performed. The results of two methods were compared.

Results: Twenty-three patients with benign salivary obstruction were included in our study. Using sialography, stenosis, lithiasis and no pathology was detected in 4, 11 and 8 patients, respectively. Using sialendoscopy stenosis, sialolithiasis and no pathology was proved in 7, 11 and 5 patients, respectively. In 16 of 23 patients (70%) sialendoscopic finding was in accordance with sialography imaging. The main difference was found in stenosis of duct system – only 50% of stenoses were detected on conventional sialography. The imaging of salivary stones was more successful. The sialography showed sialolithiasis in 80% cases.

Conclusion: Sialendsocopy is more sensitive than sialography in the detection of the SG duct obstruction patologies. Especially in diagnostics of duct stenosis sialendoscopy is more effective method.
