  • Abstract
  • Look Inside

 There are many questionable points concerning the significance as well as the mechanism of the Passavant's ridge. The authors add their investigative results to these questions. Today, it is almost a common agreement among various authors that the ridge is composed of contracting muscles of the upper pharynx as its contex.

 On the other hand there was a time when the concept that the clinical significance attached to the ridge was more in favor of an idea of hindering the proper closure of the nasopharynx. However, this concept is declining from popular favor, recently. The authors are also in agreement with this latter concept. Therefore, in cases of operation on the cleft palate no particular attention should be paid to this structure.
