Microanatomic features of unilateral condylar hyperplasia

Abstract

Microanatomic features of unilateral condylar hyperplasia (UCH) are described. The articular surface exhibited clefts with surrounding elevations, and globules varying 0.5-2 µm in diameter. The articular zone presented giant coiled fibers, and the proliferative zone was composed of small round cells. The findings suggest that degenerative changes occur in UCH, both in adult and juvenile forms.
