Absolute indications for salivary gland scintigraphy with 99mTc-pertechnetate
Abstract:
In recent years salivary gland scintigraphy has gained widespread acceptance as a useful means for evaluating salivary gland disorders. An absolute indication for this procedure exists when the ductal orifice of one or several major salivary glands cannot be found or cannot be cannulated. Clinical conditions in which this problem occurs include technical failure to probe and cannulate the duct, developmental anomalies, obstructive disorders, traumatic lesions and fistulae and the need of postsurgical information after glandular excision or after ligation or repositioning of a major excretory duct. The clinical value of scintigraphy in these conditions is demonstrated by means of case presentations.
