开窗术治疗下颌骨成釉细胞瘤术后骨密度分析

Fenestration in the Treatment of Mandibular Ameloblastoma of Bone Mineral Density Changes after Analysis

目的探讨彻底切除术后联合开窗术治疗下颌骨成釉细胞瘤的效果。方法选取2013年6月~2015年1月我院收治的下颌骨成釉细胞瘤患者30例,对肿瘤进行彻底切除后并将内层骨质0.2cm给予磨除,术后给予术区开窗,术后1个月、2个月、3个月、5个月、8个月、1年时定期复查,给予拍摄曲面断层片观察术区恢复情况并观察面部外形恢复情况,测量术区内的相对骨密度,评价其治疗效果。结果术后1个月时术区内相对骨密度较之前平均增加了4.09%,术后2个月时较术前平均增加了7.12%,术后3个月时较术前平均增加了12.25%,5个月时较术前平均增加了22.07%,8个月时较术前平均增加了27.15%,1年时复查较术前平均增加了49.06%.结论彻底切除术联合开窗术治疗下颌骨成釉细胞瘤能有效消除肿瘤,缩小术腔,促进新生骨质形成,避免肿瘤复发,促进面部外形恢复。

Objective To investigate the joint after radical resection of fenestration for the treatment of mandibular ameloblastoma. Methods From June 2013 to January 2015,30 patients with mandibular ameloblastoma in our hospital were selected. After radical resection of the tumor,the internal bone 0. 2cm was performed and postoperative fenestration was performed,after 1 month,2 months,3 months,five months,eight months,1 year,periodic review by shooting the area of surface fault observation recovery and observed facial shape recovery,relative measurement technique in bone mineral density,evaluated its therapeutic effect. Results Postoperative 1 month when the surgery was relatively reduced bone mineral density in the area before the average increased by 4. 09%,after two months grew by an average of 7. 12%compared with preoperative,postoperative 3 months grew by an average of 12. 25%,compared with preoperative 5 months grew by an average of 22. 07%,compared with preoperative at 8 months grew by an average of 27. 15%,compared with preoperative 1 in a review of the preoperative increased 49. 06% on average. Conclusions Radical resection combined fenestration in the treatment of mandibular ameloblastoma can effectively eliminate the tumor,narrow cavity,promote new bone formation,prevent tumor recurrence,promote facial appearance.
