The subjects of this study consisted of 75 patients with 83 condylar fractures, who
were admitted to Chonbuk National University Hospital from Jan. 1988, to Oct. 1995.
The purpose of this study was to compare the imagings of conventional radiograms
with those of computed tomograms and to aid in the diagnosis of condylar fractures.
Also the author evaluated the usefulness of 3-dimensional reconstructive imaging in
condylar fractures.
The obtained results were as follows :
1. The condylar fractures were observed mainly between 2nd and 4th decades, but
there was no significant difference of incidence between decades. The incidence of
condylar fractures by fracture site was subcondylar(44.6%), condlylar head(36.1%),
condylar neck(19.3%) In orders. 12 of 30 condylar head fractures were sagittal ,splitting
fractures.
2. According to the relationship of condylar head to articular fossa, the incidence of
condylar fractures was higher in Type ¥± and Type ¥². And the Incidence of
subcondylar fractures was higher in Type ¥° classified by McLennan. But there was no
significant difference of incidence between Types.
3. The more the fracture fragments were displaced, the easier the fracture patterns
were detected in conventional radiogram. The computed tomograms were also useful in
the diagnosis of sagittal splitting factures which were displaced mesially.
4. The 3-dimensional reconstructive imaging were useful in the evaluation of the
fracture patterns, but they were not useful when the size of fragment and the degree of
displacement were small.
