title: [Ventral impressions of the hypopharynx. A differential diagnostic problem].
abstract: 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.
