During this study, 38 patients (all females under 20 years old) with TMJ arthrosis who visited the Department of Oral Surgery at Nagoya University Hospital, the Department of Dent-Oral Surgery at Nagoya University Branch Hospital and Lion Foundation for Dental Health were studied.
A comparison was done on 28 females under 20 years who did not have TMJ arthrosis. The following results were obtained.
1. There were no significance differences between normal and TMJ patients in the mean value of condyle and glenoid fossa.
2. But we observed that cases had definite symptoms of smaller condyle and glenoid fossa in the troubled side.
3. In the ratio between condyle and glenoid fossa, there was no significance difference between T and N groups.
