Sialolithiasis
Pronunciation: sigh-al-oh-lith-EYE-ah-sis
Formation of calcified deposits (stones) within salivary gland ducts, commonly affecting submandibular glands and requiring surgical removal.
Full Definition
Sialolithiasis refers to the formation of calcium phosphate or calcium carbonate stones within the ductal system of major salivary glands. The submandibular gland is most commonly affected due to its alkaline secretions and longer, more tortuous duct (Wharton's duct). Patients typically present with postprandial pain and swelling as salivary flow increases but becomes obstructed by the stone. Diagnosis involves clinical examination, palpation, and imaging studies including ultrasound, CT, or sialography. Treatment ranges from conservative management with hydration and massage to surgical intervention including ductal dilation, lithotripsy, or gland excision depending on stone size and location.
Usage
Usage note: Specify affected gland and duct when documenting cases.
