Giant submandibular sialolith of remarkable size in the comma area of Wharton's duct: a case report.

s U d s l T ialolithiasis accounts for more than 50% of the saliary gland diseases, with an estimated 12 of 1,000 ersons in the adult population being affected every ear. Most salivary calculi (80%-95%) occur in the ubmandibular gland, whereas 5% to 20% are found in he parotid gland. The sublingual gland and minor alivary glands are rarely (1%-2%) affected. Male paients are affected twice as much as female patients. Multiple calculi in the submandibular gland are are, as is simultaneous lithiasis in more than 1 alivary system. Radiopacity is not a feature in 40% of arotid and 20% of submandibular stones; therefore ialography or other imaging techniques (computed omography scan, ultrasound) may be required to ocate them. Clinically, the stones are round or void, rough or smooth, and of a yellowish color. hey consist of mainly calcium phosphate with small mounts of carbonates in the form of hydroxyapatite, s well as smaller amounts of magnesium, potassium, nd ammonia. Submandibular stones are composed f 82% inorganic and 18% organic material, whereas arotid stones are composed of 49% inorganic and 1% organic material. Sialoliths commonly measure between 5 and 10 m in size, and all stones over 10 mm can be reorted as sialoliths of unusual size. Giant sialoliths easuring more than 35 mm are rare, with only round 16 cases published in the literature. Ninety-
