摘　　要：目的评估钛制关节头置换髁状突治疗颞下颌关节骨性强直的疗效。方法颞下颌关节骨性强直71例(75侧),经截骨和强直组织松解后,用纯钛制关节头置换髁状突。结果术后随访时间为6个月～13年,所有患者开口度均在3.0 cm以上,平均开口度为3.2 cm。2例复发,复发率2.8%;63例基本维持术前的咬合关系,占88.7%;8例咬合关系出现一定程度的错位,占11.4%;26例术后患侧咬合乏力伴术区不适,占36.6%。2例发生感染,占2.8%。结论钛制关节头置换髁状突是治疗成人颞下颌关节骨性强直较为理想的方法。Objective To evaluate the effect of titanium condyle prosthesis for the treatment of temporomandibular joint ankylosis.Methods The condylar prosthesis was made of 99.9% titanium and similar to the native condyle in shape.71 patients with bony ankylosis(75 joints) were treated.There were 41 males and 37 females.The age ranged from 17～62 years.After the resection of the ankylosis,the titanium prosthesis was implanted to replace the condyle.The follow-up period ranged from six monthes to 13 years.Results All of the patients achieved a postoperative interinsicial opening value of above 0.3 cm with the average value of 3.2 cm.Recurrence was seen in two cases(2.8%) during the follow-up period.Occlusive relationship was maintained in 63 cases,and was changed in 8 cases(11.4%).26 patients(36.6%) felt weak and uncomfortable in occlusion on the operated side postoperatively,only 2 cases suffered from infection and one of the prosthesis had to be removed.Conclusion Ideal outcome can be expected for patients with temporomandibular joint ankylosis by using the titanium condyle prosthesis.
