Giant submandibular sialolith presenting with sialocutaneous and sialo-oral fistula: A case report and review of literature

Abstract

Sialolithiasis is a common disease of the salivary glands and a major cause of salivary gland dysfunction. It commonly affects middle-aged and has male predominance. Submandibular gland or its duct is most commonly affected. The size of salivary calculi may vary from less than 1 mm to a few cm in the largest diameter. Salivary stones that exceed 15 mm in any dimension are classified as giant. Association of sialocutaneous or Sialo-oral fistula with salivary stones is considered rare. Long-standing stones with chronic inflammatory process may lead to fistula formation.
