【摘要】 目的:介绍髁状突游离再植行颞下颌关节重建术治疗髁突颈骨折的方法与疗效。方法:对12例伤员16侧髁突颈骨折行髁状突游离再植克氏针内固定术,术后定期行X线片及CT检查。结果:全部伤口一期愈合,追踪1～4年无关节疼痛、弹响及明显功能障碍,有3例面神经颞支损伤,2例轻度错畸形,影像学示髁状突形态多稍小且不规则。结论:本方法操作简便、损伤较轻、复位准确、固定可靠,并发症较少且轻微,适用于有严重移位的髁突颈骨折,髁状突的形态改变与长期影响需继续观察更多还原

【Abstract】 Objective: To report the method and effects of the TMJ reconstructions with condylar free implant for mandibular condylar neck fracture.Methods: TMJ reconstructions with condylar free implant were accomplished by anterior auricular approach in 16 joints of 12 cases, the condyles fixed with kirschner’s pin by submandibular approach. Results:Following up 1~4 years, all cases didn’t have any pain, click and remarkable limited movement in the reconstructed TMJS. 3 of 12 cases had temple branch of facial nerve injuried and 2 slight mal occlusion. The X ray and CT films showed the implanted condyle smallar and more irregular in contour.Conclusions: this operation for condylar neck fracture is simple to manipulate, resulting in a satisfactory clinical effects and less complications. The change of condylar contour and its long term influence to TMJ function needs to be studied further.更多还原
