Killian's dehiscence is a triangular area in the wall of the pharynx between the cricopharyngeus and thyropharyngeus which are the two parts of the inferior constrictors. It can be seen as a locus minoris resistentiae. A similar triangular area between circular fibres of the cricopharyngeus and longitudinal fibres of the esophagus is Lamier's triangle or Lamier-hackermann's area.
