BACKGROUND
The purpose of this study is to evaluate the outcomes of four patients receiving stock Biomet TMJ prosthesis for reconstruction of the TMJs.
METHODS
TMJ reconstruction with stock Biomet TMJ prosthesis was performed in four patients who had joint damages by trauma, tumor, resorption, and ankylosis, which represent the indications of alloplastic prosthesis.
RESULTS
Loss of condyle from trauma and resorption of joint are good indications for prosthesis, but the patients should be informed about limitation of jaw movement. In case of structural damage of TMJ by tumor, tumor recurrence should be considered before planning TMJ reconstruction. Considering heterotopic bone formation in case of ankylosis, periodic follow-up and special surgical technique are required.
CONCLUSIONS
Given careful treatment planning and understanding the functional limitation of TMJ prosthesis, alloplastic prosthesis is a safe and effective management option for the reconstruction of TMJs.
背景
本研究的目的是评估四名接受Biomet库存颞下颌关节假体进行颞下颌关节重建患者的治疗结果。
方法
对四名因创伤、肿瘤、吸收和关节强直导致关节损伤的患者进行了Biomet库存颞下颌关节假体的颞下颌关节重建，这些情况代表了异体假体的适应证。
结果
创伤导致的髁突缺失和关节吸收是假体植入的良好适应证，但应告知患者下颌运动受限情况。对于肿瘤导致颞下颌关节结构破坏的情况，在计划颞下颌关节重建之前应考虑肿瘤复发问题。对于关节强直的情况，考虑到异位骨形成，需要定期随访并采用特殊手术技术。
结论
经过仔细的治疗规划并了解颞下颌关节假体的功能限制，异体假体是颞下颌关节重建的一种安全有效的治疗选择。
