An unusual case of acquired unilateral condylar hypoplasia.

A case is described of acquired unilateral condylar hypoplasia, in which the right condyle seemed to have been fractured at an early age. There is evidence to suggest that the unresorbed condylar remnant persisted in the glenoid fossa and that a new condylar head had developed anterior to the articular emminence. This 'new head' showed a carrot-shaped radiolucent wedge suggestive of the condylar growth cartilage and, clinically, exhibited some growth potential. A complex composite odontome present in place of the mandibular right third molar may also have been caused by this early trauma.

Some missile injuries due to civil unrest in Northern Ireland.

Some missile injuries are reviewed after nearly 8 years of continuous warfare. A feature of many of these injuries is the early admission to hospital which has had a profound effect on the survival rate and the recovery period. Some examples are given of injuries inflicted by rubber bullets. The effects of wounding by low and high velocity missiles are described and examples given. An injury caused by a missile incorporated in a bomb is also shown.

Osteochondroma of the mandibular condyle. Case report and its management.

1. A case of osteochondroma of the temporomandibular joint simulating a unilateral condylar hyperplasia is presented. 2. The need to divide the zygomatic arch to facilitate removal of large tumors is noted. 3. The removal of the growth resulted in normal functioning of the jaws with the disappearance of the features of unilateral hyperplasia. 4. Occlusal grinding is often necessary to correct the compensatory occlusal adjustment that occurs with the rotation of the mandible in these lesions. 5. The possibility of the presence of a tumor must be kept in mind when patients present with symptoms of unilateral condylar hyperplasia.

An unusual case of 'haemorrhagic' bone cyst.

An unusual case of hemorrhagic bone cyst observed over a period of 12 years is presented. The diagnosis was confirmed by surgical exploration and histological examination of the tissue. The lesion continued to expand in spite of repeated surgical mandible. Finally, bone formation obliterated the cavity completely at the age of 19, when the facial deformity was corrected. It is suggested that this hemorrhagic bone cyst is of developmental origin. Since intramedullary haemorrhage and proliferation of giant cells are both responsible for the cavity formation and expansion, it is possible that aberrant formation of giant cells by fusion of endothelial cells of abnormal blood vessels may be an important factor in the pathogenesis of this condition.
