[Sialendoscopy: endoscopic approach to obstructive salivary gland disease]

Sialendoscopy: endoscopic approach to obstructive salivary gland defects Obstructive defects of the parotid and the submandibular gland often present themselves clinically by mealtime-related swelling of the affected salivary gland, the so-called 'mealtime syndrome'. Salivary ductal obstruction of the parotid and submandibular gland is predominantly caused by the presence of a salivary stone, a mucous plug, or by ductal stenosis. Until recently, diagnostic and treatment options for these obstructive salivary gland defects were restricted. Surgical removal of the affected salivary gland was often the treatment of choice. By applying sialendoscopy, a minimally invasive, semi rigid optical technique, it is possible to diagnose and treat obstructions which are found in the salivary ductal system. In many cases, therefore, the surgical removal of the salivary gland becomes unnecessary.
