The value of tantalum powder as a contrast medium in laryngography.
Dionosil and powdered tantalum laryngograms are compared in 18 patients with known laryngeal cancer. Dionosil more reliably defined the epiglottis, valleculae, and pyriform fossae. The glottic and subglottic regions were more clearly visualized with the use of tantalum. Both agents were equally effective in the evaluation of the supraglottis.
