Two impressions can be seen on the ventral aspect of the hypopharynx and upper oesophagus; on static images it is difficult to differentiate these from small tumours. In order to evaluate this region more accurately, we have examined 150 patients by means of rapid rate cinematography. In 52.6% we found a constant irregular or convex impression formed by the cricoid; in the other cases this was not seen or was quite minimal. In 93% a sub-cricoid impression could be demonstrated which was due to lax mucosa. Characteristically, this showed a variable appearance during the passage of a bolus. Only the cricoid impression was associated with dysphagia.
下咽和上食管腹侧可见两种压迹；在静态图像上，很难将这些压迹与小肿瘤区分开来。为了更准确地评估该区域，我们通过快速摄影术对150例患者进行了检查。在52.6%的患者中，我们发现环状软骨形成了持续的不规则或凸起压迹；在其他病例中，未观察到这种压迹或其非常轻微。在93%的患者中，可以证实存在环状软骨下压迹，这是由于黏膜松弛所致。其特征是，在食团通过期间，这种压迹表现出可变的外观。只有环状软骨压迹与吞咽困难有关。
