口腔恶性肿瘤联合根治后,常有下颌骨缺损,导致病人面部畸形,功能障碍,绐病人精神上带来很大痛苦。虽然用自体骨和其它移植物重建下颌骨取得了很多成功的经验,但目前还存在着植入物为非生物性联接,自体骨需要增加供骨的手术区及外形不够理想等问题。近年来国外文献相继报道了有关冷冻自体下颌骨作为头颈部肿瘤根治术后下颌骨再造的移植物,并取得较好效果。证明它具有自体骨移植的愈合方式,不增加新的手术创伤,重建下颌骨在形态、功能方面更优接近未切除术前的状态,移植物无抗原性等点。
Oral malignant tumor combined with radical mastectomy, often mandibular defects, leading to facial deformity, dysfunction, 绐 patients mental pain. Although many successful experiences have been gained in reconstructing the mandible with autologous bone and other implants, there are still some problems such as the non-biological implants, the need to increase the surgical area for the autologous bone and the unsatisfactory appearance. In recent years, foreign literature have reported on the frozen mandibular autologous mandibular reconstruction as the head and neck cancer after radical graft, and achieved good results. Proved that it has the way of autologous bone graft healing, no additional new surgical trauma, reconstruction of the mandible in morphology and function better close to the state before the resection, the graft without antigenic point.
