Results

Sialoliths predominated among patients aged 30 and 70 years, with no male/female predilection. A total of 78.9% of all calculi were detected in the submandibular ducts and 21.1% in the ducts of the parotid glands. The sublingual gland and the smaller salivary glands were not affected. A simultaneous stone disease of the urinary tract or the bile duct system occurred by chance (4.3%). Even regular medication in cases of other systemic diseases cannot be considered cofactors in pathogenesis.

Conclusion

Diagnosis of sialolithiasis is the result of careful consideration of patient histories demonstrating typical symptoms and clinical examination. Sonography is the first choice of imaging. Pathogenesis of sialolithiasis seems to be based on local factors within the salivary ducts and glands.
