Autologous transplant of submandibular gland as a source of tears: Demonstration of function on Tc-99m pertechnetate scintigraphy

Abstract

Severe damage to the cornea occurs if it dries. Autologous transplant of the submandibular salivary gland to supply conjunctival moisture is a therapeutic option, although saliva itself may be incompatible with a long-term healthy cornea. A 65-year-old man with previous denervation of his left lacrimal gland resulting from neurosurgical complications presented with chronic keratitis 13 years after an autologous vascularized transplant of his right submandibular gland into the temporal fossa. Its secretory duct was implanted into the conjunctival fornix. The scan was performed to determine the location and extent of functioning graft tissue before possible removal.
