钛重建板修复下颌骨缺损的临床应用

Clinical Application of Bridging Titanium Plate in Reconstruction of Mandibular Defect.

目的:研究钛重建板在修复下颌骨缺损,维持下颌骨连续性和面部形态的临床意义。方法:收集我科自 1999～2004年口腔颌面部肿瘤患者,在行根治合并下颌骨部分切除术后,用钛重建板即刻修复,对饮食功能、面部 形态恢复及并发症的发生进行回访评价。结果:回访中,对于功能和外形,有21例病人成功维持了下颌骨的连续 性,并有20例病人能饮食一般性食物,患者的开口度和开口型基本正常。对于并发症,有2例发生金属外露和1 例发生钛重建板折断,均发生在手术半年以后。结论:钛重建板即刻修复下颌骨缺损,在功能和外形方面,大多可 以获得良好效果,是一种切实可行的选择性方法。

Objective: To evaluate the clinical use of bridging titanium plate for restoration of mandibular continuity in patients who undergo bridging titanium plate reconstruction after partial mandibulectomy. Methods: From 1999 to 2004, 24 patients with oral and maxillofacial tumors were treated with radical composite partial mandibulectomy and mandibular reconstruction using a bridging plate. Complication rates and functional results were analyzed. Results: Complications included two hardware extrutions and one plate fracture, all instances of reconstruction failure were delayed for several months. 21 patients mandibular continuity was restored successfully for the duration of the follow-up period, 20 patients interviewed were able to eat a regular diet. Conclusions: Bridging titanium plate can be used as a reasonable alternative for mandibular reconstruction. The functional and cosmetic results were acceptable in many cases.
