目的探讨口内开窗术治疗下颌骨大型囊性肿瘤的临床意义。方法对32例患者行口内磨牙后区开窗术,开窗口约2 cm×1 cm大小,术后并佩戴阻塞器,防止开窗口闭合,术后定期摄片观察病变范围缩小情况,追踪观察1~1.5 a后行二期手术。结果本组32例患者行开窗术后1~1.5 a囊腔明显缩小,经二期手术后痊愈。结论开窗术可以使大型囊肿范围缩小,局部新骨形成,囊壁改变,为二期手术创造条件,保存了下颌骨外形及功能,是治疗下颌骨大型囊性肿瘤的有效方法,临床上值得推广。
Objective To investigate the clinical significance of intra-oral fenestration in the treatment of large-scale mandibular cystic neoplasm. Methods Thirty-two patients underwent posterior fenestration. The size of the fenestration was about 2 cm × 1 cm. Postoperative occluders were worn to prevent the fenestration from closing. Postoperative radiographs were taken to observe the reduction of the lesion extent. Follow-up observation 1 ~ 1.5 a after the second operation. Results The 32 patients in this group underwent 1 ~ 1.5 months after opening the capsule cavity was significantly reduced, after two surgery cured. Conclusion Window opening can narrow the scope of large cysts, local new bone formation, changes in the wall, to create the conditions for the two surgery to preserve the shape and function of the mandible, is an effective treatment of large mandibular cystic tumor, clinically worth Promotion.
