A total of 100 tantalum cine laryngotracheograms were performed in adults with documented or suspected upper airway obstruction. With appropriate precautions, tantalum powder proved to be a safe material for delineating tracheal and laryngeal abnormalities. A cine recording to document tracheomalacia as well as a careful evaluation of the larynx are useful extensions of examination of patients with suspected upper airway obstruction. Tracheomalacia was found in 35% of our series; 29% showed laryngeal abnormalities. With modifications to correct for magnification, the tantalum tracheogram gives the surgeon the exact length of trachea to be resected. When tantalum becomes approved by the Food and Drug Administration, we expect that tantalum cine laryngotracheography will be the preferred means for study of upper airway obstruction.
对有记录或疑似上气道梗阻的成人共进行了100次钽剂动态喉气管造影。采取适当的预防措施后，钽粉被证明是一种用于描绘气管和喉部异常的安全材料。记录气管软化的动态记录以及对喉部的仔细评估是对疑似上气道梗阻患者检查的有用扩展。在我们的系列研究中，35%发现有气管软化；29%显示有喉部异常。通过修正放大率，钽剂气管造影能为外科医生提供待切除气管的确切长度。当钽剂获得美国食品药品监督管理局批准后，我们预计钽剂动态喉气管造影将成为研究上气道梗阻的首选方法。
