Severe and mild complications could only be detected in damaged transplant bed (radical operation and radiation exposure, traumatic lesions) in osteoplastic reconstruction of the mandible with avascular cancellous bone transfer using a titanium carrier. Altogether, we rate this method as more favorable compared to an avascular block transplant because of advantages in handling the system in the surgical technique, contouring of the problem zones in the chin and mandibular angle region, more simple transplant extraction and greater resistance to infections. Owing to the high osteogenic potency of the cancellous bone, a relatively slight tendency to secondary absorption was found. We hence still value avascular cancellous bone transfer as a method which can be recommended for reconstruction of small and medium-size mandibular defects (up to about 6 cm) in good to moderate transplant bed. At present, we restrict vascularized transfer of the cortico-cancellous block transplant to larger mandibular defects and transplant beds which are not ideal for substitution after radical operation and radiation exposure.
在使用钛载体进行无血管松质骨移植的下颌骨骨成形重建中,严重和轻度并发症仅在受损的移植床(根治性手术和放疗、创伤性病变)中被检测到。总体而言,与无血管块状移植相比,我们认为这种方法更具优势,因为在手术技术中处理该系统、修整下巴和下颌角区域的问题区域、更简单的移植取出以及更强的抗感染能力方面具有优势。由于松质骨的高成骨能力,发现继发性吸收的倾向相对较小。因此,我们仍然重视无血管松质骨移植,认为它是一种可推荐用于在良好至中等移植床中重建中小尺寸下颌骨缺损(达约6厘米)的方法。目前,我们将皮质-松质骨块状移植的血管化移植限制用于较大的下颌骨缺损以及在根治性手术和放疗后不适合替代的不理想移植床。
