OBJECTIVE
To preliminarily evaluate the method of using titanium condylar protheses in management of traumatic temporomandibular joint ankylosis.
METHODS
Between August 2006 and April 2008, titanium condylar replacement was performed in 5 male patients. Preoperative CT datum of patient was obtained and a resin model was then produced and used as a reference to select a suitable titanium condyle for reconstruction of the joint. In the operation, the bony ankylosis was removed. According to the preoperation planning, the selected prosthesis was inserted and fixed to the distal mandibular segment. The results were assessed by means of examinations and measurements postoperatively and during follow-up.
RESULTS
The 5 patients received alloplastic replacement of 6 condyles. Three patients were under follow-up and follow-up time ranged from 8 months to 2 years and 6 months. The mean mouth opening was 30 mm. Two patients had good occlusion and one patient developed a slight open bite.
CONCLUSIONS
Prosthetic condylar replacement can provide a choice for management of traumatic temporomandibular joint ankylosis.
目的
初步评估采用钛髁突假体治疗创伤性颞下颌关节强直的方法。
方法
2006年8月至2008年4月，对5例男性患者行钛髁突置换术。获取患者术前CT数据，制作树脂模型，以此为参考选择合适的钛髁突用于关节重建。手术中，去除骨性强直。根据术前规划，将选定的假体植入并固定于下颌骨远心段。术后及随访期间通过检查和测量对结果进行评估。
结果
5例患者共行6个髁突的异体置换。3例患者获得随访，随访时间为8个月至2年6个月。平均开口度为30毫米。2例患者咬合良好，1例患者出现轻度开牙合。
结论
髁突假体置换可为创伤性颞下颌关节强直的治疗提供一种选择。
