我们自1979年5月～1982年,对4例因造釉细胞瘤切除下颌骨的病人,应用显微外科的方法,用耳大神经移植修复下齿槽神经,全部获得成功,现报告于下。一、手术方法(一) 下颌骨切除步骤与一般颌骨切除基本相同,但在截骨范围上两端比正常需要切骨的少1cm,待肿瘤骨截出后,于骨断端用咬骨钳或骨凿去除约1cm长的骨质,以暴露出该段下齿槽神经作移植时吻合用。(二) 切取耳大神经:于原下颌骨切除的切口内向胸锁乳突肌方向加以分离即可取得所需长度的耳大神经。(三) 准备植骨床。植骨床的准备与一般下颌骨植骨同,但不要损伤准备用以吻合的下 We from 1979 May to 1982, 4 cases of ameloblastoma resection of the mandible patients, the use of microsurgical methods, with auricular nerve transplantation to repair the inferior alveolar nerve, all were successful, are reported in the next . First, the surgical methods (A) mandibular resection steps and the general jaw resection is basically the same, but in the range of osteotomy at both ends than the normal need to cut bone less 1cm, until the tumor bone cut, the end of the bone with bony Pliers or osteotome to remove about 1cm long bone to expose the lower alveolar nerve for transplantation coincidence. (B) cut the great auricular nerve: in the original mandibular incision incision to the sternocleidomastoid muscle to be separated to obtain the desired length of the great auricular nerve. (C) prepare bone graft bed. Bone bed preparation and general mandibular bone graft with the same, but do not damage to prepare to match the next
