The aim of this study was to evaluate the clinical and radiologic results of Zimmer Biomet stock prostheses (Jacksonville, FL) in temporomandibular joint replacement after surgical modifications during at least 1 year of follow-up.
We recruited patients treated by Zimmer Biomet stock prostheses after technical modifications, including digital templates, autogenous ipsilateral bone grafting from the mandible to the fossa, salvaging of the disc remnant and suturing it to the medial aspect of the prosthesis, and fat grafts from a retromandibular incision, between 2010 and 2016. Clinical examination findings including maximal incisal opening; visual analog scale scores for pain, diet, and mandibular movement; and quality of life were compared before the operation and at least 1 year postoperatively. The status of the fossa bone graft was evaluated by computed tomography examination.
The study comprised 38 joints in 33 patients with diagnoses including osteoarthritis, ankylosis, and neoplasm. Compared with before the operation, maximal incisal opening and visual analog scale scores for diet, function, and pain level, as well as the quality-of-life survey score, were considerably improved during the last follow-up. Computed tomography scans showed all bone grafts were completely healed within the fossa 1 year after surgery. There was no ectopic bone formation, screw loosening, or component displacement or breakage.
Our surgical modifications of Zimmer Biomet stock prostheses showed good results for at least 1 year of follow-up.
本研究旨在评估捷迈邦美库存假体（佛罗里达州杰克逊维尔）在颞下颌关节置换手术改良后至少1年随访期内的临床和影像学结果。
我们招募了在2010年至2016年间接受捷迈邦美库存假体治疗的患者，这些治疗包括技术改良，如数字模板、从下颌骨至关节窝的自体同侧骨移植、保留盘状残余物并将其缝合至假体内侧、以及从下颌后切口进行脂肪移植。比较手术前和术后至少1年的临床检查结果，包括最大切牙开口度；疼痛、饮食和下颌运动的视觉模拟量表评分；以及生活质量。通过计算机断层扫描检查评估关节窝骨移植的状况。
该研究纳入了33例患者的38个关节，诊断包括骨关节炎、关节强直和肿瘤。与手术前相比，在末次随访时，最大切牙开口度、饮食、功能和疼痛程度的视觉模拟量表评分以及生活质量调查评分均有显著改善。计算机断层扫描显示，术后1年所有骨移植在关节窝内均完全愈合。没有异位骨形成、螺钉松动或部件移位或断裂。
我们对捷迈邦美库存假体的手术改良在至少1年的随访期内显示出良好的效果。
