目的:观察应用带髁突假体的钛板即刻修复下颌骨造釉细胞瘤术后颌骨缺损的治疗效果。方法:12例下颌骨造釉细胞瘤患者,行髁突切除术后,即刻植入带髁突的假体。记录面部外形、开口度、创口愈合情况、咬合关系及钛板固位情况。结果:11例患者对面部外形恢复满意,1例对面型恢复不满意,术前术后开口度无显著差异(P>0.05),上下颌牙咬合关系恢复良好,1例钛板术后1年发生断裂。结论:钛髁突假体行造釉细胞瘤术后颌骨缺损的修复是一种安全有效的方法。
Objective: To observe the effect of using titanium plate with condylar prosthesis to repair mandibular defects of mandibular ameloblastoma immediately. Methods: Twelve patients with mandibular ameloblastoma were implanted with condylar prosthesis immediately after condylar resection. Record facial shape, opening degree, wound healing, occlusal relationship and titanium plate retention. Results: Eleven patients were satisfied with facial appearance recovery, one case was dissatisfied with facial restoration, there was no significant difference in preoperative and postoperative opening degree (P> 0.05), occlusion between mandibular teeth recovered well, and one case Fracture occurred. Conclusion: It is a safe and effective method to repair postoperative jaw defects in titanium condylar prosthesis.
