我们采用局部搔刮后液氮灌注深低温冷冻治疗颌骨造釉胞瘤获得明显近期效果,介绍如下。 方法 在局麻下拔除患区松动牙,经牙槽嵴对造釉细胞瘤进行彻底搔刮,然后将液氮灌注于骨腔内,反复冻融三次,注意控制体位使液氮能与骨腔之各面接触,冻后骨腔用碘仿纱条填塞,定期随防。 注意事项: 1.选择健康情况较好的青年患者,骨再生能力较强者。 2.术前加病理确诊,并照片确定手术范围。 3.既要彻底刮除肿瘤又要尽可能防止病理性骨折。 4.灌注时注意保护软组织。
We use local scraping liquid nitrogen perfusion deep cryogenic cryogenic treatment of maxillary alveolar neoplasms obtained significant short-term effect, described below. Methods To remove the loose tooth under local anesthesia and completely scratch the ameloblastoma by alveolar crest. Then, liquid nitrogen was perfused into the bone cavity and repeatedly frozen and thawed three times. Attention should be paid to control the position so that liquid nitrogen and bone cavity All aspects of contact, frozen bone cavity filled with iodoform gauze, regularly with the anti. Matters needing attention: 1 select the young patients with better health, stronger bone regeneration ability. Preoperative plus pathological diagnosis, and photos to determine the scope of the operation. 3. It is necessary to completely remove the tumor but also to prevent pathological fractures as much as possible. 4. Note the protection of soft tissue perfusion.
