AIM
Fibular bone grafts are considered as one of the best choices for reconstruction of the condyle. However, little data are available on bone remodelling after such reconstruction. The purpose of this study was to evaluate the long-term radiological outcome.
PATIENTS AND METHODS
Eleven patients underwent condylar reconstruction with a free fibular transplant. In all cases the end of the fibular graft was placed into the glenoid fossa under the intact temporomandibular joint (TMJ) disc. Evaluation consisted of digital width and length measurement of the end of the fibula on panorex studies.
RESULTS
Remodelling of the end of the neocondyle was found and consisted of rounding off and narrowing of the end of the transplant.
CONCLUSION
The most likely explanation for these changes is the fact that the TMJ disc was preserved.
目的
腓骨移植被认为是髁突重建的最佳选择之一。然而，关于这种重建后骨重塑的数据很少。本研究的目的是评估长期影像学结果。
患者与方法
11例患者接受了游离腓骨移植髁突重建术。在所有病例中，腓骨移植的末端置于完整的颞下颌关节（TMJ）盘下方的关节盂窝内。评估包括在全景片上测量腓骨末端的宽度和长度。
结果
发现新髁末端有重塑，表现为移植末端变圆和变窄。
结论
这些变化最可能的解释是TMJ盘得以保留。
