Abstract

|
|
authors made a radiographic study with computed tomograms(CT) after 11.8 months on the average of trauma for the 7 adult mandibular condyle fractures, which were dislocated from the fossa at the head or neck. All cases showed good treatment
results
clinically, with more than 50 mm of maximal interincisal opening and 7-12 mm(average 10.8 & 9.1 mm) of lateral movements.
@ES The results of CT radiographic examinations were as follows :
@EN 1. The fractured condylar fragments were all in bony union with distal ramal stump of the mandible and there was no evidence of fibrous nor bony ankylosis between fractured condyles and skull bases or zygomas.
2. The newly formed condyles were bigger than the original ones and projected medially, with flat articular surface of condylar heads. But they approximated the original condyiar shapes.
3. New articular or glenoid surfaces articulating with condylar heads were situated more antero-medially at the skull bases and previous glenoid fossas were shallowed by some sclerosis.
4. The ramal heights were obsreved to be shorter, even though no even though no evidence of facial asymmetry clinically. And there were 3 cases in which bony spicules were showed at the medial cortices of rami at the insertion of medial
pterygoid
muscles.
5. The lateral pterygoid muscles appeared to be shorter and plumper and their attachments were relatively good enough.
