作者对14例下颌骨肿瘤患者进行下颌骨切除,冰冻再植术(良性10例,恶性4例)。经临床检查、X线照片、99mTC—MDP骨扫描评价,随访时间长达二年半以上,成功11例,感染2例,死亡1例。发现自体肿瘤下颌骨冰冻后再植既能杀灭全部肿瘤细胞,又能诱导新骨生长。并对冰冻治疗下颌骨肿瘤机制、手术成败关键进行了讨论。认为该方法简单、经济,既能恢复下颌骨复杂的功能,又能维持面部外形,是理想的下颌骨缺损修复方法。
The authors performed mandibular resection and frozen replantation in 14 patients with mandibular tumor (benign and malignant in 4 cases). Clinical examination, X-ray, 99mTC-MDP bone scan evaluation, follow-up time of more than two years and a half, successful in 11 cases, 2 cases of infection, 1 case of death. Found that autologous tumor mandibular frozen replantation can kill all tumor cells, but also induce new bone growth. The key to the success of cryotherapy in the treatment of mandibular tumor is discussed. Considering that this method is simple and economical, it not only restores the complex function of the mandible but also maintains the appearance of the face. It is an ideal method for repairing mandibular defects.
