近年来,由于显微外科的发展,使下颌骨肿瘤切除术后,即刻用带血管蒂的自体游离肋骨、髂骨等移植修复下颌骨缺损,使下颌骨外科向前跨进一步。 79年以来我们曾成功的用带血管神经的自体游离肋骨移植修复下颌骨缺损。但技术条件要求较高,适应症需严格选择,且手术时间较长,不易普及。为了简化手术程序,又不影响植骨的成活率及骨痂形成,我们将Siems方法进行改进,用带胸锁乳突肌
In recent years, due to the development of microsurgery, the mandibular defect is repaired immediately after the resection of the mandibular tumor by means of the autologous free rib-bearing pedicle graft and the iliac bone graft, so that the mandibular surgery advances further. For 79 years, we have succeeded in repairing mandibular defects with autologous free rib grafts with vascular nerves. However, high technical requirements, indications need to be strictly selected, and the longer operative time, not easy to popularize. In order to simplify the surgical procedure, without affecting the survival rate of bone graft and callus formation, we improved the Siems method with sternocleidomastoid muscle
