Abstract
This study was intended to evaluate condyle position and the relationship of condyle position change and post surgical relapse following the sagittal split ramus osteotomy for mandible setback in 25 patients by paired t-test and multiple
regression
analysis. We used oblique transcranial and cephalometric radiographs taken before operation, immediate after operation, and at least 6 months post operatively.
1. In oblique transcranial view, posterior joint space was decreased immediate after operation and increased 6 months after operation. To compare the measurement before and 6 months after operation, there was no statistically significant change
in
over
all joint spaces(P>0.05).
2. The joint spaces changed under the 0.2mm were 30%, 0.2mm to 1.0 mm were 60.7%, above 1.0mm were 9.3%, This result reveals that condyle position was relatively reproduced to pre-operative state.
3. Statistically, the amount of mandible set back didn't influence the post operative relapse(p>0.05).
4. Statistically, the amount of mandible set back didn't influence the condylar displacement(p>0.05), and the amount of joint space change didn't influence the post operative relapse. (p>0.05) The changes in joint space is in the standard
tracing
error
or within the adaptive capacity of the individual, it was too small to influence the stability of surgery.
