Abstract.

The aim of the study was to determine whether salivary gland scintigraphy using technetium-99m pertechnetate is suitable for checking the vitality and function after autotransplantation of the submandibular salivary gland in patients with dry eye syndrome. To this end, 56 scintigraphic studies in 20 patients have so far been performed. In addition, these scans were evaluated by a region of interest (ROI) technique in order to examine tracer uptake in the early and late stages after surgery. We have been able to prove that in this special respect, too, the salivary gland scintigraphy is suitable for assessing reliably the vitality and function of the transplanted gland. The secretion into the eye and thus the patency of the efferent duct can also be displayed. This proved to be particularly valuable in those cases in which at first no secretion could be seen in the clinical examination. In patients with uncertain excretory function, we were able to distinguish between non-vitality and lack of patency of the secretory duct. Using ROI evaluation, no significant decrease in the salivary function has been detected in long-term follow-up, now extending to 1 year after surgery.
