Abstract
In the precious report*, the authors described how the stenotic larynx was visualized on X-ray films with powdered tantalum. Further studies were performed in patients with laryngeal stenosis and the precious report was confirmed in the facts that many cases of stenotic larynx were only visualized with powdered contrast medium such as tantalum.
The hypopharynx and the cephalic part of the stenotic larynx could be easily visualized wih Dionosil, but the stenotic part and its caudal part could be visualized much successfully with Powdered Tantalum. The cephalic part with Dionosil and the caudal part with Tantalum were contrasted simultaneously.
In most of laryngeal stenosis, tracheotomy was already performed because of difficulty breathing, and the powdered tantalum was sprayed into the trachea through the tracheotomy stoma.
Tantalum laryngography was also useful in follow-up of the patients because of a lach of complication of difficulty breathing.
