ABSTRACT

Our aim was to investigate the role of retention of the condylar cartilage in open reduction and internal fixation (ORIF) of intracapsular condylar fractures (ICFs) in growing goat’s by histopathological observation. Twelve goats 6 months old were randomly divided into three groups. ICFs were created bilaterally in mandibular condyles and treated with ORIF. On the one side (n=4) the condylar cartilage was removed, and on the other side (n=4) it was retained. Condyles in the control group (n=4) were untouched. Experimental animals were sacrificed at the following intervals, 3 months and 6 months postoperatively. Specimens were harvested for tissue slice observation. Tissue slices of the condyles with the articular cartilage retained showed a normal TMJ structure and no differences with the normal condylar tissue structures. The basic structures of cartilage layer of the condyle with articular cartilage removed disappeared. The surface of mature bone tissue of the condyle directly connected with fibrous tissue of the articular disc. The results of this study suggest that retaining condylar cartilage in the ORIF for ICF of growing goats has no harmful effect on condylar growth, but removal can lead to the articular disc adhesion and limit growth.
