[Giant sialolithiasis: Diagnosis and management. Case reports].

Sialolithiasis is one of the most frequent form of calcifications in the maxillofacial area. 0.45% of the population is affected by symptoms caused by salivary calculi, though the estimated frequency including asymptomatic form may exceed 1% in adult population. Radiographs presenting a large portion of the maxillofacial region (panoramic radiography, computed tomography) could detect salivary calculi with high accuracy. The size of the sialoliths is usually less than 10 mm in diameter. Salivary calculi larger than 15 mm (considering the largest diameter) are classified as giant sialoliths and most of them are located in the submandibular gland or in its duct. Two unusually large submandibular salivary calculi cases are represented (diameters of 27 and 34 mm), whereas in one of the cases development and dimensional changes of the calculus are described via a seven years period. This case report represents diagnostic and therapeutic consequences in giant sialolithiasis and demonstrates possible differential diagnostic difficulties. Orv. Hetil., 2016, 157(49), 1967-1972.
