Abstract

Six cases of bilateral coronoid hyperplasia resulting in limitation of mandibular movement were presented. The positional interrelation between the coronoid process and the zygomatic bone and arch were examined on lateral and posterior-anterior cephalograms.
The result was that in these cases the tip of the coronoid process was situated higher above the keyridge, closer to the posterior aspect of the zygomatic bone and horizontally nearer to the inner aspect of the zygomatic arch than in the controls.
Cephalograms were very helpful in examining the anatomic position of the coronoid process.
