摘要
总结了26例真性颞下颌关节强直,用以钛合金及碳/碳复合非生物材料制成的半关节行颞下颌关节半置换术,取得了较好效果。手术的成功不仅在于选择最佳术式还在于关节材料的选择。手术要点为:切除骨性融合区后的间隙应达2.5～3.0cm,否则易复发。要求依据张闭口及咬合关系维持置换侧下颌支的高度,并达到关节的点面接触,以防止术后错咬合且有利于咀嚼功能的恢复。同期行颏部水平截骨颏成形术,以取得美容效果。
The goal of treating true ankylosis of TMJ was to reconstruct the function of the joint and to prevent relapse.The authors have operated on 26 patients with true ankylosis of TMJ using semi- joint replacement of compound non-biological materials.Functionally and cosmetically good results were demonstrated after two to thirteen months' follow-up.
