Bilateral giant submandibular sialoliths and the role for salivary endoscopy.

Salivary stones larger than 15 mm are classified as giant sialoliths. They are uncommon in the practice of otolaryngology, and their management has always been a therapeutic challenge. Traditionally, when they cannot be retrieved by marsupialization, removal of the salivary gland has been advocated. Sialendoscopy and the recent development of combined endoscopic and external approaches for extraction of large stones with preservation of the major salivary glands are promising. We present the first case of simultaneous bilateral giant sialoliths, and the first report that associates giant sialoliths and the use of salivary endoscopy. In this case, both giant stones were removed with the assistance of a salivary endoscope and without removing the submandibular glands.
